mHealth Interventions for Lifestyle and Risk Factor Modification in Coronary Heart Disease: Randomized Controlled Trial

Opportunities and challenges of lifestyle intervention-based digital therapeutics in LDL-C management: a scoping review

Background

In recent decades, the prevalence of dyslipidemia, especially high low-density lipoprotein cholesterol (LDL-C), has risen sharply in China. Although lifestyle interventions are important, traditional face-to-face approaches have limitations. Digital Therapeutics (DTx) can provide an effective solution by delivering remote medical interventions to patients via software and hardware, thereby optimizing existing clinical treatment methods with enhanced convenience and accessibility.

Objectives

This study aims to explore the current evidence on the effect of lifestyle intervention-based Digital Therapeutics (LI-DTx) on high LDL-C, and to analyze their advantages and disadvantages.

Eligibility criteria

This scoping review examines clinical studies assessing the effects of DTx on LDL-C levels. Papers were included in the final analysis if there was evidence that DTx had effects on lowering LDL-C levels.

Sources of evidence

Papers that were published between January 2014 and December 2023 were included in the PubMed database.

Charting methods

Data extracted from the publications included country, year, study type, study population, sample size, study duration, intervention, and changes in LDL-C level.

Results

A total of 23 target literature were identified. Twenty-one studies confirmed that LI-DTx could optimize the LDL-C level through remote lifestyle interventions such as diet, exercise, medication, and health education, of which 14 studies reported a significant reduction in LDL-C level (p < 0.05). In the future, the development and design of DTx will need to improve intelligence, personalization, applicability, real-time performance, and data security; integrate with traditional healthcare systems; facilitate multidisciplinary collaboration in dyslipidemia management; and enhance long-term patient engagement with DTx platforms.

Conclusion

LI-DTx may offer a more effective and sustainable solution for LDL-C management, although several challenges remain. Further randomized controlled clinical trials are needed to provide scientific support for its efficacy and safety.

The digital prescription: A systematic review and meta-analysis of smartphone apps for blood pressure control

OBJECTIVE

Assess the effectiveness of digital health interventions (DHIs) in reducing blood pressure (BP) among individuals with high blood pressure and identify the impact of age, sex, and phone-based delivery methods on BP.

METHODS

A systematic review and meta-analysis was undertaken according to the PRISMA and JBI. A comprehensive search was conducted across multiple databases. Randomised controlled trials (RCTs), mixed methods, descriptive, and experimental studies enrolling adult patients (≥18 years) with high BP and containing DHIs with blood pressure management aspect were included. We used a random-effects meta-analysis weighted mean difference (MD) between the comparison groups to pool data from the included studies. The outcome included the pooled MD reflecting systolic (SBP) or diastolic (DBP) change from baseline to 6-month period. Risk of bias was assessed using standardised tools.

RESULTS

Thirty-six studies with 33,826 participants were included in the systematic review. The pooled estimate (26 RCTs) showed a significant reduction in SBP (MD = -1.45 mmHg, 95 % CI: -2.18 to -0.71) but not in DBP (MD = -0.50 mmHg, 95 % CI: -1.03 to 0.03), with evidence of some heterogeneity. Subgroup analysis indicated that smartphone app interventions were more effective in lowering SBP than short message services (SMS) or mobile phone calls. Additionally, the interventions significantly reduced the SBP compared with the control, regardless of participant sex.

CONCLUSION

Our findings indicate that DHIs, particularly smartphone apps, can lower SBP after 6 months in individuals with hypertension or high-risk factors, although changes might not be clinically significant. Further research is needed to understand the long-term impact and optimal implementation of DHIs for BP management across diverse populations.

Effectiveness of digital health interventions for telemedicine/telehealth for managing blood pressure in adults: a systematic review and meta-analysis

This systematic review and meta-analysis included randomized controlled trials or observational studies that compare digital health interventions (DHIs) for telemedicine/telehealth versus usual care for managing blood pressure (BP) in adults. We searched PubMed, Cochrane CENTRAL, and IchuShi-Web, and used a random-effects meta-analysis of the weighted mean difference (MD) between the comparison groups to pool data from the included studies. The outcome included the pooled MD of office BP from baseline to each follow-up period. This meta-analysis considered 117 studies with 68677 participants as eligible. The 3-month intervention period reduced office systolic BP (SBP) compared with usual care in 38 studies (MD: -3.21 mmHg [95% confidence interval: -4.51 to -1.90]), with evidence of heterogeneity. Office SBP across intervention periods demonstrated comparable effects (3-, 6- [54 studies], 12- [43 studies], and >12-month periods [9 studies]). The benefits for office diastolic BP were similar to those for office SBP. Additionally, the interventions significantly reduced the office SBP compared with the control, regardless of the mode of intervention delivery (smartphone apps [38 studies], text messages [35 studies], and websites [34 studies]) or type of facility (medical [74 studies] vs. non-medical [33 studies]). The interventions were more effective in 41 hypertension cohorts compared with 66 non-hypertension cohorts (-4.81 mmHg [-6.33, -3.29] vs. -2.17 mmHg [-3.15, -1.19], P = 0.006 for heterogeneity). In conclusion, DHIs for telemedicine/telehealth improved BP management compared with usual care. The effectiveness with heterogeneity should be considered, as prudent for implementing evidence-based medicine. This meta-analysis considered 117 studies with 68677 participants eligible. The DHIs for telemedicine/telehealth reduced office BP compared with usual care, regardless of intervention duration, intervention delivery mode, facility type, and cohort type. Additionally, the DHIs reduced the risk of uncontrolled BP compared with usual care, regardless of intervention duration, intervention delivery mode, and facility type.

Perceptions of healthcare professionals and patients with cardiovascular diseases on mHealth lifestyle apps: A qualitative study

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death globally and is predominantly associated with a cluster of lifestyle risk factors. Mobile health (mHealth) apps offer the potential to overcome traditional barriers by supporting healthy lifestyle behaviours. However, knowledge about perceptions of mHealth lifestyle apps among healthcare professionals and people with CVD is sparse. This study examined barriers and facilitators of using the mHealth apps for healthy lifestyle support among healthcare professionals and CVD patients.

METHODS

We conducted an in-depth qualitative study employing individual semi-structured interviews with 8 CVD healthcare professionals and 4 patients with CVD in Australia. Participants were asked open-ended questions about their perceptions and experiences with mHealth lifestyle apps. A thematic analysis approach was used to establish perceived barriers and facilitators for mHealth lifestyle apps.

RESULTS

Most participants perceived mHealth lifestyle apps as useful. The key perceptions of facilitators included features for tailoring to personal needs, low costs and wide availability of the apps and addressing barriers to use like reminders. Both healthcare professionals and patients identified the strengths and weaknesses regarding the usefulness of mHealth lifestyle apps. Healthcare professionals and patients perceived several barriers to mHealth app use including trustworthiness, scientific validity, language barriers, the capability of using an app or digital literacy, costs for some commercial apps, and accessibility of an app for low-income groups.

CONCLUSION

Lifestyle apps provide an opportunity for better patient and healthcare professional communications, however, several barriers including improving digital health literacy and scientific validations of the apps are required before being recommended in clinical practice. Findings from this study can inform potential mHealth lifestyle app design to meet the demands of users. Addressing these barriers effectively can enhance the adoption and efficacy of mHealth apps, ultimately contributing to improved CVD management and healthier lifestyle behaviours.

Knowledge, attitude, and practice toward coronary heart disease secondary prevention among coronary heart disease patients in Shanghai, China

BACKGROUND

This study aimed to investigate knowledge, attitude, and practice (KAP) toward coronary heart disease (CHD) secondary prevention among CHD patients.

METHODS

This web-based cross-sectional study enrolled patients with CHD who visited the Yangpu District Central Hospital in Shanghai (China) between October 18, 2022, and March 25, 2023. The administered questionnaire assessed demographic information and KAP; factors associated with good practice were identified by multivariate logistic regression.

RESULTS

A total of 507 participants were included in the study, with 361 (71.2%) being male. In terms of education, 125 (24.7%) had a junior high school level or below. The mean scores for knowledge, attitudes, and practices were 31.28 ± 7.30 (possible range: 0-42), 54.09 ± 3.33 (possible range: 12-60), and 35.48 ± 3.36 (possible range: 11-55), respectively. For specific knowledge items on CHD, 57.6% of participants correctly identified that women are more susceptible to CHD. Physical labor and emotional excitement as triggers for CHD were correctly recognized by 94.1%. The need for long-term medication and follow-up after a CHD diagnosis had the highest correctness rate at 98.8%. Additionally, 84.6% correctly understood that recurrence of CHD is possible after PCI surgery. Multivariate analysis indicated that smoking and diabetes status were significantly associated with Practice scores. Current smokers reported lower practice levels than never smokers (OR = 2.858, 95% CI: 1.442-5.662, P = 0.003). Participants with diabetes reported higher practice levels than those without diabetes (OR = 4.169, 95% CI: 2.329-7.463, P < 0.001).

CONCLUSIONS

Patients with CHD in Shanghai, China, demonstrated good knowledge and positive attitudes toward CHD secondary prevention, although there were some gaps in actual practice behaviors. Enhancing targeted educational interventions and support systems in clinical settings may help bridge these gaps and improve adherence to recommended preventive practices.

Strategies to Improve Health Care Provider Prescription of and Patient Adherence to Guideline-Recommended Cardiovascular Medications for Atherosclerotic Occlusive Disease: Protocol for Two Systematic Reviews and Meta-Analyses of Randomized Controlled Trials

BACKGROUND

In patients with atherosclerotic occlusive diseases, systematic reviews and meta-analyses of randomized controlled trials (RCTs) report that antiplatelets, statins, and antihypertensives reduce the risk of major adverse cardiac events, need for revascularization procedures, mortality, and health care resource use. However, evidence suggests that these patients are not prescribed these medications adequately or do not adhere to them once prescribed.

OBJECTIVE

We aim to systematically review and meta-analyze RCTs examining the effectiveness of implementation or adherence-supporting strategies for improving health care provider prescription of, or patient adherence to, guideline-recommended cardiovascular medications in patients with atherosclerotic occlusive disease.

METHODS

We designed and reported the protocol according to the PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis-Protocols) statement. We will search MEDLINE, Embase, The Cochrane Central Register of Controlled Trials, PsycINFO, and CINAHL from their inception. RCTs examining implementation or adherence-supporting strategies for improving prescription of, or adherence to, guideline-recommended cardiovascular medications in adults with cerebrovascular disease, coronary artery disease, peripheral artery disease, or polyvascular disease (>1 of these diseases) will be included. Two investigators will independently review identified titles/abstracts and full-text studies, extract data, assess the risk of bias (using the Cochrane tool), and classify implementation or adherence-supporting strategies using the refined Cochrane Effective Practice and Organization of Care (EPOC) taxonomy (for strategies aimed at improving prescription) and Behavior Change Wheel (BCW; for adherence-supporting strategies). We will narratively synthesize data describing which implementation or adherence-supporting strategies have been evaluated across RCTs, and their reported effectiveness at improving prescription of, or adherence to, guideline-recommended cardiovascular medications (primary outcomes) and patient-important outcomes and health care resource use (secondary outcomes) within refined EPOC taxonomy levels and BCW interventions and policies. Where limited clinical heterogeneity exists between RCTs, estimates describing the effectiveness of implementation or adherence-supporting strategies within different refined EPOC taxonomy levels and BCW interventions and policies will be pooled using random-effects models. Stratified meta-analyses and meta-regressions will assess if strategy effectiveness varies by recruited patient populations, prescriber types, clinical practice settings, and study design characteristics. GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) will be used to communicate evidence certainty.

RESULTS

The search was completed on June 6, 2023. Database searches and the PubMed "related articles" feature identified 4319 unique citations for title/abstract screening. We are currently screening titles/abstracts.

CONCLUSIONS

These studies will identify which implementation and adherence-supporting strategies are being used (and in which combinations) across RCTs for improving the prescription of, or adherence to, guideline-recommended cardiovascular medications in adults with atherosclerotic occlusive diseases. They will also determine the effectiveness of currently trialed implementation and adherence-supporting strategies, and whether effectiveness varies by patient, prescriber, or clinical practice setting traits.

Mitochondria dysfunction: A trigger for cardiovascular diseases in systemic lupus erythematosus

Cardiovascular disease (CVD), including pericarditis, myocarditis, sudden cardiac death, coronary heart disease, and stroke, are leading contributors to morbidity and mortality in systemic lupus erythematosus (SLE) patients. Emerging evidence highlights mitochondrial dysfunction as a key driver of cardiovascular pathology in SLE, with impaired oxidative phosphorylation, altered membrane potential, and disrupted metabolic processes promoting oxidative stress, inflammatory activation, and endothelial dysfunction. This review critically examines mitochondrial contributions to CVD in SLE, comparing these mechanisms with those in non-SLE CVD to highlight SLE-specific mitochondrial vulnerabilities. Furthermore, we discuss preclinical and clinical findings supporting mitochondrial pathways as potential therapeutic targets, aiming to bridge gaps in current understanding and outline future research directions. By synthesizing current knowledge of mitochondrial dysregulation, this review proposes therapeutic strategies to improve cardiovascular outcomes and advance patient care in SLE.

Patient-Centric Approach to Personalized Electronic Medical Records via QR Code in Japan

Government policies in the United States and the European Union promote standardization and value creation in the use of FAIR (findability, accessibility, interoperability, and reusability) data, which can enhance trust in digital health systems and is crucial for their success. Trust is built through elements such as FAIR data access, interoperability, and improved communication, which are essential for fostering innovation in digital health technologies. This Viewpoint aims to report on exploratory research demonstrating the feasibility of testing a patient-centric data flow model facilitating semantic interoperability on precision medical information. In this global trend, the interoperable interface called Sync for Science-J (S4S-J) for linking electronic medical records (EMRs) and personal health records was launched as part of the Basic Policy for Economic and Fiscal Management and Reform in Japan. S4S-J controls data distribution consisting of EMR and patient-generated health data and converts this information into QR codes that can be scanned by mobile apps. This system facilitates data sharing based on personal information beliefs and unlocks siloed Internet of Things systems with a privacy preference manager. In line with Japanese information handling practices, the development of a mobile cloud network will lower barriers to entry and enable accelerated data sharing. To ensure cross-compatibility and compliance with future international data standardization, S4S-J conforms to the Health Level 7 Fast Health Care Interoperability Resources standard and uses the international standardized logical observation identifiers names and codes (LOINC) to redefine medical terms used in different terminology standards in different medical fields. It is developed as an applied standard in medical information intended for industry, health care services, and research through secondary use of data. A multicenter collaborative study was initiated to investigate the effectiveness of this system; this was a registered, multicenter, randomized controlled clinical trial, the EMBRACE study of the mobile health app M♡Link for hyperglycemic disorders in pregnancy, which implements an EMR-personal health record interoperable interface via S4S-J. Nevertheless, the aforementioned new challenges, the pivotal Health Level 7 Fast Health Care Interoperability Resources system, and LOINC data mapping were successfully implemented. Moreover, the preliminary input of EMR-integrated patient-generated health data was successfully shared between authorized medical facilities and health care providers in accordance with the patients' preferences. The patient-centric data flow of the S4S-J in Japan is expected to guarantee the right to data portability, which promotes the maximum benefit of use by patients themselves, which in turn contributes to the promotion of open science.

Comparative effectiveness of different interventions on adherence to exercise-based CR among patients after percutaneous coronary intervention: a network meta-analysis of randomized controlled trials

BACKGROUND

Exercise-based phase II cardiac rehabilitation is critical for post-PCI patients, but adherence to exercise-based phase II cardiac rehabilitation remains low. Many studies aimed at improving adherence have been conducted in recent years, but the most effective interventions remain unclear. Hence, the objective of this study was to evaluate the effectiveness and ranks of various interventions in enhancing adherence to exercise-based phase II cardiac rehabilitation for post-PCI patients.

METHODS

A network meta-analysis employing random effects was utilized to evaluate the effectiveness of different interventions. Bias evaluation was performed via the revised Cochrane risk of bias tool, with data analysis performed using STATA v15.0. The surface under the cumulative ranking was used to estimate the rankings among different interventions.

RESULTS

In the final analysis, 30 RCTs with 4267 patients across 17 different interventions were included. The results showed that patients who received home-based cardiac rehabilitation combined with mobile health intervention had the best adherence to exercise-based phase II cardiac rehabilitation (83.8%), followed by hospital-based cardiac rehabilitation combined with mobile health intervention (79.9%).

CONCLUSIONS

This network meta-analysis identified home-based CR + mobile health intervention and hospital-based CR + mobile health intervention as the top two ranked interventions for improving adherence to exercise-based phase II CR in post-PCI patients. Healthcare providers may consider prioritizing the use of home-based cardiac rehabilitation combined with mobile health intervention in clinical practice, but still need to evaluate factors such as patient preference and Medicare reimbursement availability to develop customized interventions that are not only safe and effective but also satisfying to the patient.

Strategies for Effective Communication in Hypertension Management: Validation of Messages from a Mobile Application to Assist Hypertensive Older Adults in Adherence to Treatment, Nutrition and Physical Activity

BACKGROUND

Poor adherence to antihypertensive treatment is a common problem among elderly hypertensive patients and one of the leading causes of inadequate blood pressure control. In this sense, it is essential to improve strategies for effective communication in managing hypertension treatment for this group.

OBJECTIVE

This study aimed to validate the text messages of a mobile application to aid adherence to antihypertensive treatment, nutrition, and physical activity among older adults with hypertension treated in Brazilian public primary health care.

METHODS

This descriptive, methodological development study with a quantitative approach was carried out between March and August 2024.

RESULTS

A total of 27 messages were constructed and validated by 13 experts, and this stage was divided into two rounds. The Content Validity index and percentage of agreement were used in the validation process. The messages were developed using theory, national guidelines, validation, and expert review.

CONCLUSIONS

Text messages for adherence to antihypertensive treatment involving medication, nutrition, and physical activity have enormous potential with the target audience studied.

Prescriptive Appropriateness and Efficacy of Cholesterol-Lowering Drugs in a Secondary Prevention Setting-A Retrospective Analysis from Two Italian Cardiac Rehabilitation Centers

Background: Treatment of CV risk factors, such as cholesterol level, represents one of the main goals to reduce atherosclerotic burden. The aim of this study was to investigate the prescriptive appropriateness of cholesterol-lowering drugs among patients who experienced an atherosclerotic CV disease (ASCVD). Methods: We investigated 155 patients who underwent cardiac rehabilitation in 2020. The European Society of Cardiology (ESC) 2021 guidelines on CV disease prevention and 2019 ESC Guidelines on dyslipidemias were followed to detect the appropriateness of prescription. SCORE2 and SCORE2-OP risk estimations were used to detect patients' CV risk profiles. Patients were divided into three groups: 1 (n = 118) patients admitted for their first CV event, 2A (n = 18) patients who experienced a previous CV event years before, and 2B (n = 19) patients admitted for a new event with a previous CV event 2 years before. Low-density lipoprotein (LDL) cholesterol level was detected at the time of admission to the hospital, during cardiac rehabilitation, and at the first visit after rehabilitation. Results: The statistics for our study participants, with a mean age of 66.1 years, were: 72.4% overweight/obese, 63.9% diabetic, 72.5% smokers, 93.0% hypertensives, and 91.7% had dyslipidemias. In group 1, only 5.1% had a low/moderate risk, 44.1% presented a high risk, and 50.8% a very high risk according to calculators. The average LDL levels were 115.8 mg/dL (2.99 mol/L) upon admission to the hospital, 66.4 mg/dL (1.72 mmol/L) at the time of cardiac rehabilitation, and 64.8 mg/dL (1.67 mmol/L) at the subsequent medical visit. In the overall group, only 36.0% had LDL < 55 mg/dL (1.42 mmol/L). In group 1, 79.4% were treated with high-intensity statin alone or plus ezetimibe; in group 2A, the percentage increased up to 87.5%, while group 2B 33.4% was treated with high-intensity statin plus ezetimibe and 33.3% were treated with PCSK9 inhibitors. Conclusions: This retrospective study confirms the importance of properly calculating CV risk profiles. The main limitations for the efficacy of lipid-lowering drugs were: patient's compliance, drugs side effects, lifestyle habits, and collaboration with a general practitioner.

Comparative efficacy and adherence of telehealth cardiac rehabilitation interventions for patients with cardiovascular disease: A systematic review and network meta-analysis

BACKGROUND

Traditional center-based cardiac rehabilitation had low adherence rates. With the increasing utilization of digital technology in healthcare services, telehealth can overcome common barriers to improve adherence, and some telehealth interventions have been proven safe and effective. However, it remains unclear which telehealth intervention types can maximize the efficacy and adherence for cardiac rehabilitation.

OBJECTIVE

To compare the effect of different types of telehealth interventions on the efficacy and adherence of patients with cardiovascular disease in cardiac rehabilitation.

DESIGN

Systematic review and network meta-analysis.

METHODS

We systematically searched PubMed, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, ProQuest, Scopus, and Embase databases for randomized controlled trials of telehealth cardiac rehabilitation for cardiovascular disease patients from January 2013 to March 2024. The primary outcomes were peak oxygen uptake (VO2 peak) and adherence. Secondary outcomes included 6-minute walking distance, moderate-to-vigorous intensity physical activity, depression, self-reported quality of life, and patient satisfaction. The study protocol has been registered on PROSPERO (ID: CRD42023459643).

RESULTS

This network meta-analysis included 46 randomized controlled trials. The results indicated that telehealth cardiac rehabilitation improved VO2 peak, 6-minute walking distance, moderate-to-vigorous intensity physical activity, and adherence. The surface under the cumulative ranking curve (SUCRA) results showed that the Wearable Devices + Smartphone Applications (SUCRA = 86.8 %, mean rank = 1.7) was the most effective telehealth intervention for improving VO2 peak. The Smartphone Applications + Instant Communication Tools (SUCRA = 74.2 %, mean rank = 2.6) was the most effective telehealth intervention for promoting adherence.

CONCLUSIONS

Combining two or more types of telehealth interventions was found to be effective. Future efforts should prioritize conducting high-quality randomized controlled trials to identify more effective combinations with traditional cardiac rehabilitation.

A Cross-Sectional Study of Risk Factors for Coronary Heart Disease in Secondary Prevention for Patients With the Disease in China

AIMS

To explore risk factors for Coronary Heart Disease (CHD) in secondary prevention for patients with the disease in China.

DESIGN

Cross-sectional study.

METHODS

A two-stage sampling method was used (stratified sampling and systematic sampling). Patients who met WHO diagnostic criteria for CHD, had the capacity to give informed consent and volunteered to participate were recruited from five districts in Hengyang city, Hunan province, China. Six instruments were used: A general socio-demographic questionnaire, Coronary Heart Disease Self-Management Scale, International Physical Activity Questionnaires, Chinese Eight-Item Morisky Medication Adherence Scale, Zung's Self-Rating Anxiety Scale and Sexual Health Questionnaires. Participants completed the questionnaires in person or via telephone. Single-factor correlation analysis, Pearson correlation analysis and multiple linear regression analysis were carried out.

RESULTS

A total of 373 patients were recruited with a mean age of 66.25 years (standard deviation = 9.98). The mean score was 57.00 (14.23) for self-management, 5.41 (1.82) for medication adherence, 53.61 (9.26) for anxiety, 8.66 (3.18) for sexual knowledge and 22.20 (9.68) for the need for sexual health education. The median was 1563.90 MET-min/day for total energy consumption of physical activity. Self-management, physical activity, medication adherence, anxiety and sexual health were significantly correlated with a range of demographic variables (age, gender, marital status, occupation, education levels, types of medical insurance, personal monthly income, living arrangements) and illness-related variables (illness duration, number of hospital admissions, type of therapy, number of other chronic diseases, cardiac function grading and BMI).

CONCLUSION

This research has showed the risk factors related to self-management skills, medication adherence, anxiety, physical activity, sexual knowledge and the need for sexual health education in secondary prevention for patients with CHD. Health professionals play an important role in helping patients reduce risk factors for CHD to minimise its reoccurrence and mortality.

RELEVANCE TO CLINICAL PRACTICE

Both hospital-based and community-based health professionals, especially nurses, have an important role to play in developing and implementing health promotion interventions to help patients with CHD reduce risk factors for the disease and thus reduce mortality.

PATIENT OR PUBLIC CONTRIBUTION

No patient contribution. Community nursing staff contributed to the design of the general socio-demographic questionnaire for this study.

REPORTING METHOD

The STROBE checklist was used to ensure comprehensive reporting (Appendix S1).

Assessing the Effectiveness of eHealth Interventions to Manage Multiple Lifestyle Risk Behaviors Among Older Adults: Systematic Review and Meta-Analysis

BACKGROUND

Developing adverse lifestyle behaviors increases the risk of a variety of chronic age-related diseases, including cardiovascular disease, obesity, and Alzheimer disease. There is limited evidence regarding the effectiveness of eHealth-based multiple health behavior change (MHBC) interventions to manage lifestyle risk behaviors.

OBJECTIVE

The purpose of this systematic evaluation was to assess the effectiveness of eHealth MHBC interventions in changing ≥2 major lifestyle risk behaviors in people aged ≥50 years.

METHODS

The literature search was conducted in 6 electronic databases-PubMed, Embase, Web of Science, Scopus, Cochrane Library, and SPORTDiscus-from inception to May 1, 2024. Eligible studies were randomized controlled trials of eHealth interventions targeting ≥2 of 6 behaviors of interest: alcohol use, smoking, diet, physical activity (PA), sedentary behavior, and sleep.

RESULTS

A total of 34 articles with 35 studies were included. eHealth-based MHBC interventions significantly increased smoking cessation rates (odds ratio 2.09, 95% CI 1.62-2.70; P<.001), fruit intake (standardized mean difference [SMD] 0.18, 95% CI 0.04-0.32; P=.01), vegetable intake (SMD 0.17, 95% CI 0.05-0.28; P=.003), self-reported total PA (SMD 0.22, 95% CI 0.02-0.43; P=.03), and objectively measured moderate to vigorous PA (SMD 0.25, 95% CI 0.09-0.41; P=.002); in addition, the interventions decreased fat intake (SMD -0.23, 95% CI -0.33 to -0.13; P<.001). No effects were observed for alcohol use, sedentary behavior, or sleep. A sensitivity analysis was conducted to test the robustness of the pooled results. Moreover, the certainty of evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework.

CONCLUSIONS

eHealth-based MHBC interventions may be a promising strategy to increase PA, improve diet, and reduce smoking among older adults. However, the effect sizes were small. Further high-quality, older adult-oriented research is needed to develop eHealth interventions that can change multiple behaviors.

Efficacy of a Mobile Health App (eMOTIVA) Regarding Compliance With Cardiac Rehabilitation Guidelines in Patients With Coronary Artery Disease: Randomized Controlled Clinical Trial

BACKGROUND

Cardiac rehabilitation is fundamental among patients recovering from a coronary event, and mHealth technology may constitute a useful tool that provides guidelines based on scientific evidence in an entertaining, attractive, and user-friendly format.

OBJECTIVE

This study aimed to compare the efficacy of an mHealth intervention involving the eMOTIVA app and that of usual care regarding compliance with cardiac rehabilitation guidelines in terms of lifestyle, cardiovascular risk factors, and satisfaction among patients with acute coronary syndrome.

METHODS

A randomized controlled clinical trial with a parallel group design was conducted. It included 300 patients (mHealth group, 150; control group, 150) who underwent percutaneous coronary intervention for acute coronary syndrome. Both groups underwent evaluations initially (during hospitalization) and after 3 and 6 months (face-to-face consultations). The eMOTIVA app incorporates a virtual classroom providing audio and video information about a healthy lifestyle, a section for self-recording cardiovascular risk factors, and a section for feedback messages and gamification. The primary outcome variables were (1) adherence to the Mediterranean diet and the frequency of consumption of food; (2) physical activity level, sedentary time, and exercise capacity; (3) smoking cessation and nicotine dependence; (4) level of knowledge about cardiovascular risk factors; and (5) app satisfaction and usability.

RESULTS

The study analyzed 287 patients (mHealth group, 145; control group, 142). Most participants were male (207/300, 69.0%), and the mean age was 62.53 (SD 8.65) years. Significant improvements were observed in the mHealth group compared with the control group at 6 months in terms of (1) adherence to the Mediterranean diet (mean 11.92, SD 1.70 vs 8.92, SD 2.66 points; P<.001) and frequency of eating foods (red meat [≤1/week]: 141/143, 97.9% vs 96/141, 68.1%; industrial pastries [<2/week]: 129/143, 89.6% vs 80/141, 56.8%; oily fish [≥2/week]: 124/143, 86.1% vs 64/141, 41.4%; vegetables [≥2/day]: 130/143, 90.3% vs 78/141, 55.3%; fruit [≥2/day]: 128/143, 88.9% vs 85/141, 60.2%; all P<.001); (2) physical activity (mean 2112.66, SD 1196.67 vs 1372.60, SD 944.62 metabolic equivalents/week; P<.001) and sedentary time (mean 8.38, SD 1.88 vs 9.59, SD 2.09 hours; P<.001); (3) exercise capacity (distance: mean 473.49, SD 102.28 vs 447.25, SD 93.68 meters; P=.04); and (4) level of knowledge (mean 117.85, SD 3.83 vs 111.00, SD 7.11 points; P<.001). App satisfaction was high (mean 42.53, SD 6.38 points), and its usability was excellent (mean 95.60, SD 4.03 points).

CONCLUSIONS

With the eMOTIVA app, favorable results were obtained in the intervention group in terms of adherence to the Mediterranean diet, frequency of eating certain foods, physical activity, sedentary time, exercise capacity, knowledge level, systolic blood pressure, heart rate, and blood sugar level. Furthermore, participants reported high app satisfaction and rated its usability as excellent. Thus, this innovative tool is very promising.

Health-promotion interventions targeting multiple behaviors: A meta-analytic review of general and behavior-specific processes of change

Although health-promotion interventions that recommend changes across multiple behavioral domains are a newer alternative to single-behavior interventions, their general efficacy and their mechanisms of change have not been fully ascertained. This comprehensive meta-analysis (6,878 effect sizes from 803 independent samples from 364 research reports, N = 186,729 participants) examined the association between the number of behavioral recommendations in multiple-behavior interventions and behavioral and clinical change across eight domains (i.e., diet, smoking, exercise, HIV [Human Immunodeficiency Virus] prevention, HIV testing, HIV treatment, alcohol use, and substance use). Results showed a positive, linear effect of the number of behavioral recommendations associated with behavioral and clinical change across all domains, although approximately 87% of the samples included between 0 and 4 behavioral recommendations. This linear relation was mediated by improvements in the psychological well-being of intervention recipients and, in several domains (i.e., HIV, alcohol use, and drug use), suggested behavioral cuing. However, changes in information, motivation, and behavioral skills did not mediate the impact of the number of recommendations on behavioral and clinical change. The implications of these findings for theory and future intervention design are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Persuasive Systems Design Trends in Coronary Heart Disease Management: Scoping Review of Randomized Controlled Trials

BACKGROUND

Behavior change support systems (BCSSs) have the potential to help people maintain healthy lifestyles and aid in the self-management of coronary heart disease (CHD). The Persuasive Systems Design (PSD) model is a framework for designing and evaluating systems designed to support lifestyle modifications and health behavior change using information and communication technology. However, evidence for the underlying design principles behind BCSSs for CHD has not been extensively reported in the literature.

OBJECTIVE

This scoping review aims to identify existing health BCSSs for CHD, report the characteristics of these systems, and describe the persuasion context and persuasive design principles of these systems based on the PSD framework.

METHODS

Using the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines, 3 digital databases (Scopus, Web of Science, and MEDLINE) were searched between 2010 to 2022. The major inclusion criteria for studies were in accordance with the PICO (Population, Intervention, Comparison, and Outcome) approach.

RESULTS

Searches conducted in the databases identified 1195 papers, among which 30 were identified as eligible for the review. The most interesting characteristics of the BCSSs were the predominant use of primary task support principles, followed by dialogue support and credibility support and the sparing use of social support principles. Theories of behavior change such as the Social Cognitive Theory and Self-Efficacy Theory were used often to underpin these systems. However, significant trends in the use of persuasive system features on par with behavior change theories could not be established from the reviewed studies. This points to the fact that there is still no theoretical consensus on how best to design interventions to promote behavior change in patients with CHD.

CONCLUSIONS

Our results highlight key software features for designing BCSSs for the prevention and management of CHD. We encourage designers of behavior change interventions to evaluate the techniques that contributed to the success of the intervention. Future research should focus on evaluating the effectiveness of the interventions, persuasive design principles, and behavior change theories using research methodologies such as meta-analysis.

An App-Based Physical Activity Intervention in Community-Dwelling Chinese-, Tagalog-, and Vietnamese-Speaking Americans: Single-Arm Intervention Study

BACKGROUND

Physical inactivity is associated with adverse health outcomes among Asian Americans, who exhibit the least adherence to physical activity guidelines compared with other racial and ethnic groups. Mobile app-based interventions are a promising approach to promote healthy behaviors. However, there is a lack of app-based interventions focused on improving physical activity among Asian Americans whose primary language is not English.

OBJECTIVE

This pilot study aimed to assess the feasibility and acceptability of a 5-week intervention using a culturally and linguistically adapted, evidence-based mobile phone app with an accelerometer program, to promote physical activity among Chinese-, Tagalog-, or Vietnamese-speaking Americans.

METHODS

Participants were recruited through collaborations with community-based organizations. The intervention was adapted from a 12-month physical activity randomized controlled trial involving the app and accelerometer for English-speaking adults. Sociodemographic characteristics, lifestyle factors, and physical measurements were collected at the baseline visit. A 7-day run-in period was conducted to screen for the participants who could wear a Fitbit One (Fitbit LLC) accelerometer and complete the app's daily step diary. During the 4-week intervention period, participants wore the accelerometer and reported their daily steps in the app. Participants also received daily messages to reinforce key contents taught during an in-person educational session, remind them to input steps, and provide tailored feedback. Feasibility measures were the percentage of eligible participants completing the run-in period and the percentage of participants who used the app diary for at least 5 out of 7 days during the intervention period. We conducted poststudy participant interviews to explore overall intervention acceptability.

RESULTS

A total of 19 participants were enrolled at the beginning of the study with a mean age of 47 (SD 13.3; range 29-70) years, and 58% (n=11) of them were female. Of the participants, 26% (n=5) were Chinese, 32% (n=6) were Vietnamese, and 42% (n=8) were Filipino. All participants met the run-in criteria to proceed with the intervention. Adherence to the app diary ranged from 74% (n=14) in week 2 to 95% (n=18) in week 4. The daily average steps per week from accelerometers increased each week from 8451 (SD 3378) steps during the run-in period to 10,930 (SD 4213) steps in week 4. Participants reported positive experiences including an increased motivation to walk and the enjoyment of being able to monitor their physical activity.

CONCLUSIONS

This is the first pilot study of a multicomponent intervention and evidence-based mobile phone app to promote physical activity among Asian Americans who use apps in traditional Chinese, Tagalog, or Vietnamese, which demonstrated high feasibility and acceptability. Future work focused on multilingual mobile apps to address disparities in physical inactivity among Asian Americans should be considered.

Effectiveness of the Green Heart Smartphone Application as a Self-Management Intervention for Hypertension and Dyslipidemia: A Randomized Clinical Trial

BACKGROUND

Cardiovascular disease (CVD) is a major global health concern, the leading cause of death and disability. Thus, preventive interventions targeting modifiable risk factors are essential. Mobile-health technologies have emerged as promising tools for improving prevention by modifying risk factors. We created the "Green Heart" mobile app to help coronary artery disease (CAD) patients control their risk factors. The app has three modules: smoking cessation, dyslipidemia (DLP) control, and blood pressure (BP) management. This study evaluated the app's performance in monitoring hypertension (HTN) and DLP among known CAD cases.

METHODS

A randomized controlled trial enrolled 1590 CAD subjects, including 1114 hypertensive patients and 1488 subjects with DLP, and assigned them randomly to paper-based education or application-based groups.

RESULTS

Regarding HTN, after 6 months, we finally analyzed 545 and 546 hypertensive patients, assigned to the conventional and app groups, respectively. Patients in the app group were more likely to have their BP managed successfully (88.6% vs. 78.5%; P<0.001). The app group showed higher odds of successful BP management (odds ratio [OR]: 2.13; 95% CI: 1.51 - 3.03). Regarding DLP, we analyzed 728 patients in the conventional and 714 patients in the app group. A higher percentage of patients in the app group (24.8%) had low-density lipoprotein cholesterol (LDL-C) levels less than 70 mg/dL (16.1%; P<0.001). The app group showed higher odds of reducing LDL-C (OR: 1.72; 95% CI: 1.32-2.26).

CONCLUSION

We found that using the Green Heart app in the self-monitoring setting significantly improved BP and DLP management across the study population.

Mobile Health Interventions: A Frontier for Mitigating the Global Burden of Cardiovascular Disease

Mobile health (mHealth) interventions have emerged as a promising approach for cardiovascular disease (CVD) prevention and management. The proliferation of smartphones and wearable devices enables convenient access to health monitoring tools, educational resources, and communication with healthcare providers. mHealth interventions encompass mobile apps, wearables, and telehealth services that empower users to monitor vital signs, adhere to medication, and adopt healthier lifestyles. Their effectiveness hinges on user engagement, leveraging behavioral science principles and gamification strategies. While mHealth offers advantages such as personalized support and increased reach, it faces challenges pertaining to data privacy, security concerns, and resistance from healthcare providers. Robust encryption and adherence to regulations like the Health Insurance Portability and Accountability Act (HIPAA) are crucial for safeguarding sensitive health data. Integrating mHealth into clinical workflows can enhance healthcare delivery, but organizational adjustments are necessary. The future of mHealth is closely intertwined with artificial intelligence (AI), enabling remote monitoring, predictive algorithms, and data-driven insights. Tech giants are incorporating advanced health-tracking capabilities into their devices, paving the way for personalized wellness approaches. However, mHealth grapples with ethical dilemmas surrounding data ownership, privacy breaches, and inadvertent data capture. Despite its potential, mHealth necessitates a concerted effort to overcome obstacles and ensure ethical, secure, and practical implementation. Addressing technical challenges, fostering standardization, and promoting equitable access are pivotal for unlocking the transformative impact of mHealth on cardiovascular health and reducing the global burden of CVD.

The effectiveness of green heart application to manage modifiable risk factors of coronary artery disease in Tehran Heart Center: Study protocol for a randomized controlled trial

The burden of cardiovascular disease (CVD) is diminishing in developed countries. However, in middle- and low-income countries the CVD death rates are growing. CVD is the most common cause of death and disability in Iran and accounts for nearly half of all mortalities in Iranians. Therefore, preventive strategies by risk factor modification are a top priority in the country. Recently, Mobile-Health (mHealth) technology has been the focus of increasing interest in improving the delivery of cardiovascular prevention, targeting a combination of modifiable risk factors. This parallel-group single-blinded randomized controlled trial study has been designed to evaluate the impact of using a mHealth application on risk factors control. Individuals aged between 25 and 75 years who have documented CVD by coronary angiography in Tehran Heart Center and have at least one uncontrolled risk factor from the three including hypertension, dyslipidemia, and current cigarette smoking will be included. We are going to randomize 1544 patients into two study arms as follows: 1- Intervention: usual care + mHealth 2- Control: usual care + paper-based recommendations and educational materials. After 3 and 6 months of follow-up, the status of risk factors will be determined through outpatient visits and face-to-face interviews for both arms. Outcome: Successful risk factor control will be measured after 3 and 6 months. Nowadays, mHealth is becoming increasingly popular, providing a good opportunity for constant monitoring of risk factors and changing health behavior in a target population. Meanwhile, providing evidence for the effectiveness of health intervention delivery using mobile technologies could help health providers encourage their at-risk population to stop smoking, control blood pressure and blood cholesterol, and participate in regular physical activity. While the burden of CVD is growing in developing countries, this type of intervention can be a cost-effective way to reduce it in these countries.

Mobile phone text messaging for medication adherence in secondary prevention of cardiovascular disease

BACKGROUND

Cardiovascular diseases (CVDs) are the leading cause of death globally, accounting for almost 18 million deaths annually. People with CVDs have a five times greater chance of suffering a recurrent cardiovascular event than people without known CVDs. Although drug interventions have been shown to be cost-effective in reducing the risk of recurrent cardiovascular events, adherence to medication remains suboptimal. As a scalable and cost-effective approach, mobile phone text messaging presents an opportunity to convey health information, deliver electronic reminders, and encourage behaviour change. However, it is uncertain whether text messaging can improve medication adherence and clinical outcomes. This is an update of a Cochrane review published in 2017.

OBJECTIVES

To evaluate the benefits and harms of mobile phone text messaging for improving medication adherence in people with CVDs compared to usual care.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four other databases, and two trial registers. We also checked the reference lists of all primary included studies and relevant systematic reviews and meta-analyses. The date of the latest search was 30 August 2023.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) with participants with established arterial occlusive events. We included trials investigating interventions using short message service (SMS) or multimedia messaging service (MMS) with the aim of improving adherence to medication for the secondary prevention of cardiovascular events. The comparator was usual care. We excluded cluster-RCTs and quasi-RCTs.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were medication adherence, fatal cardiovascular events, non-fatal cardiovascular events, and combined CVD event. Secondary outcomes were low-density lipoprotein cholesterol for the effect of statins, blood pressure for antihypertensive drugs, heart rate for the effect of beta-blockers, urinary 11-dehydrothromboxane B2 for the antiplatelet effects of aspirin, adverse effects, and patient-reported experience. We used GRADE to assess the certainty of the evidence for each outcome.

MAIN RESULTS

We included 18 RCTs involving a total of 8136 participants with CVDs. We identified 11 new studies in the review update and seven studies in the previous version of the review. Participants had various CVDs including acute coronary syndrome, coronary heart disease, stroke, myocardial infarction, and angina. All studies were conducted in middle- and high-income countries, with no studies conducted in low-income countries. The mean age of participants was 53 to 64 years. Participants were recruited from hospitals or cardiac rehabilitation facilities. Follow-up ranged from one to 12 months. There was variation in the characteristics of text messages amongst studies (e.g. delivery method, frequency, theoretical grounding, content used, personalisation, and directionality). The content of text messages varied across studies, but generally included medication reminders and healthy lifestyle information such as diet, physical activity, and weight loss. Text messages offered advice, motivation, social support, and health education to promote behaviour changes and regular medication-taking. We assessed risk of bias for all studies as high, as all studies had at least one domain at unclear or high risk of bias. Medication adherence Due to different evaluation score systems and inconsistent definitions applied for the measurement of medication adherence, we did not conduct meta-analysis for medication adherence. Ten out of 18 studies showed a beneficial effect of mobile phone text messaging for medication adherence compared to usual care, whereas the other eight studies showed either a reduction or no difference in medication adherence with text messaging compared to usual care. Overall, the evidence is very uncertain about the effects of mobile phone text messaging for medication adherence when compared to usual care. Fatal cardiovascular events Text messaging may have little to no effect on fatal cardiovascular events compared to usual care (odds ratio 0.83, 95% confidence interval (CI) 0.47 to 1.45; 4 studies, 1654 participants; low-certainty evidence). Non-fatal cardiovascular events We found very low-certainty evidence that text messaging may have little to no effect on non-fatal cardiovascular events. Two studies reported non-fatal cardiovascular events, neither of which found evidence of a difference between groups. Combined CVD events We found very low-certainty evidence that text messaging may have little to no effect on combined CVD events. Only one study reported combined CVD events, and did not find evidence of a difference between groups. Low-density lipoprotein cholesterol Text messaging may have little to no effect on low-density lipoprotein cholesterol compared to usual care (mean difference (MD) -1.79 mg/dL, 95% CI -4.71 to 1.12; 8 studies, 4983 participants; very low-certainty evidence). Blood pressure Text messaging may have little to no effect on systolic blood pressure (MD -0.93 mmHg, 95% CI -3.55 to 1.69; 8 studies, 5173 participants; very low-certainty evidence) and diastolic blood pressure (MD -1.00 mmHg, 95% CI -2.49 to 0.50; 5 studies, 3137 participants; very low-certainty evidence) when compared to usual care. Heart rate Text messaging may have little to no effect on heart rate compared to usual care (MD -0.46 beats per minute, 95% CI -1.74 to 0.82; 4 studies, 2946 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

Due to limited evidence, we are uncertain if text messaging reduces medication adherence, fatal and non-fatal cardiovascular events, and combined cardiovascular events in people with cardiovascular diseases when compared to usual care. Furthermore, text messaging may result in little or no effect on low-density lipoprotein cholesterol, blood pressure, and heart rate compared to usual care. The included studies were of low methodological quality, and no studies assessed the effects of text messaging in low-income countries or beyond the 12-month follow-up. Long-term and high-quality randomised trials are needed, particularly in low-income countries.

Effectiveness of cardiac rehabilitation programs on medication adherence in patients with cardiovascular disease: A systematic review and meta-analysis

Background

Education to improve medication adherence is one of the core components of cardiac rehabilitation (CR) programs. However, the evidence on the effectiveness of CR programs on medication adherence is conflicting. Therefore, we aimed to summarize the effectiveness of CR programs versus standard care on medication adherence in patients with cardiovascular disease.

Methods

A systematic review and meta-analysis was conducted. Seven databases and clinical trial registries were searched for published and unpublished articles from database inception to 09 Feb 2022. Only randomised controlled trials and quasi-experimental studies were included. Two independent reviewers conducted the screening, extraction, and appraisal. The JBI methodology for effectiveness reviews and PRISMA 2020 guidelines were followed. A statistical meta-analysis of included studies was pooled using RevMan version 5.4.1.

Results

In total 33 studies were included with 16,677 participants. CR programs increased medication adherence by 14 % (RR = 1.14; 95 % CI: 1.07 to 1.22; p = 0.0002) with low degree of evidence certainty. CR also lowered the risk of dying by 17 % (RR = 0.83; 95 % CI: 0.69 to 1.00; p = 0.05); primary care and emergency department visit by mean difference of 0.19 (SMD = -0.19; 95 % CI: -0.30 to -0.08; p = 0.0008); and improved quality of life by 0.93 (SMD = 0.93; 95 % CI: 0.38 to 1.49; p = 0.0010). But no significant difference was observed in lipid profiles, except with total cholesterol (SMD = -0.26; 95 % CI: -0.44 to -0.07; p = 0.006) and blood pressure levels.

Conclusions

CR improves medication adherence with a low degree of evidence certainty and non-significant changes in lipid and blood pressure levels. This result requires further investigation.

The effects of behavioral intervention on anthropometric, clinical, and biochemical parameters in patients with polycystic ovary syndrome: a systematic review and meta-analysis

Objective

To evaluate the effects of behavioral intervention for polycystic ovary syndrome (PCOS).

Methods

Electronic databases were searched, including Pubmed, Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to 1 April 2023. Inclusion criteria for this study required a diagnosis of PCOS. Interventions of interest included behavioral intervention and routine treatment compared with routine treatment. The studies included in the analysis were designed as randomized controlled trials (RCTs). We conducted meta-analyses following the recommended guidelines. The data was analyzed using either the random effects model or fixed effects model. The results of the studies were expressed as either mean differences (MD) or standardized mean differences (SMD) along with their corresponding 95% confidence intervals (CIs).

Results

Eight RCTs were identified, including data from 744 patients (415 in the intervention group and 329 in the control group). The results indicate an improvement in the effectiveness of behavioral interventions for weight loss (MD: -1.07; 95% CI: -2.1 to 0.03; I2 = 0%; P=0.04), body mass index (BMI) (MD: -1.12; 95% CI: -1.92 to -0.33; I2 = 73%; P=0.006), waist circumference (MD: -3.97; 95% CI: -5.64 to -2.29; I2 = 0%; P<0.00001), quality of life about weight (MD: 0.58; 95% CI: 0.15 to 1.02; I2 = 0%; P=0.008), depression (SMD: -1.12; 95% CI: -2.35 to -0.07; I2 = 92%; P=0.04), and triglycerides (MD: -0.16; 95% CI: -0.27 to -0.05; I2 = 27%; P=0.004). However, there were no significant differences in menstrual cycles, hirsutism, emotions, and infertility. The study also found that behavioral interventions had no significant effect on systolic and diastolic blood pressure, high-density lipoprotein, low-density lipoprotein, homeostasis model assessment of insulin resistance, testosterone, total cholesterol, fasting glucose, fasting insulin, hemoglobin A1C, and sex hormone binding globulin.

Conclusion

Behavioral intervention supplementation contributes to weight loss, reduction in BMI and waist circumference, and improvement in depression among patients with PCOS. However, no significant improvement was observed in the biochemical index and quality of life. The long-term effects of behavioral intervention for PCOS remain unclear due to limitations in the quality of the studies involved and the short duration of treatment.

Effectiveness and Feasibility of Telehealth-Based Dietary Interventions Targeting Cardiovascular Disease Risk Factors: Systematic Review and Meta-Analysis

BACKGROUND

Telehealth-based dietary interventions were recommended for cardiovascular disease (CVD) management during the COVID-19 pandemic; however, data regarding their effectiveness and feasibility are limited.

OBJECTIVE

We aimed to examine (1) the effectiveness of telehealth-based dietary interventions in improving clinical CVD risk factors and (2) the feasibility of these interventions among individuals with CVD.

METHODS

To conduct this systematic review and meta-analysis of randomized controlled trials (RCTs), 2 investigators searched PubMed, Cochrane Library, Web of Science, and ClinicalTrials.gov databases based on predetermined search terms and included English-language RCTs published between January 2000 and July 2022. The Cochrane Risk of Bias tool was used to assess RCT quality. To evaluate intervention effectiveness, weight, BMI, systolic and diastolic blood pressure, and levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, or blood glucose were compared postintervention in telehealth and usual care (UC) groups. Feasibility was determined through the number of participants retained in intervention and UC groups. Pooled data for each CVD outcome were analyzed using a random effects model. Mean difference (MD), standardized MD, or risk ratio were calculated using R software.

RESULTS

A total of 13 RCTs with 3013 participants were included in the analysis to assess the effectiveness and feasibility of telehealth-based dietary interventions among individuals with CVD. Participants had a mean age of 61.0 (SD 3.7) years, and 18.5% (n=559) were women. Approximately one-third of RCTs were conducted in the United States (n=4, 31%). Included studies used telephone, app, text, audio-visual media, or website-based interventions. Of the 13 included studies, 3 were of high quality, 9 were of moderate quality, and only 1 was of low quality. Pooled estimates showed systolic blood pressure (MD -2.74, 95% CI -4.93 to -0.56) and low-density lipoprotein cholesterol (standardized MD -0.11, 95% CI -0.19 to -0.03) to be significantly improved among individuals with CVD as a result of telehealth-based dietary interventions compared to UC. No significant difference in effectiveness was detected for weight, BMI, and levels of diastolic blood pressure, total cholesterol, high-density lipoprotein, and triglycerides between telehealth-based dietary interventions and UC among those with CVD. There was no significant difference between the feasibility of telehealth-based dietary interventions versus UC. Significant I2 indicated moderate to considerable heterogeneity.

CONCLUSIONS

Telehealth-based dietary interventions show promise in addressing CVD risk factors.

Effects of Ninjurin 2 polymorphisms on susceptibility to coronary heart disease

OBJECTIVE

The aim of this study was to explore the effects of Ninjurin 2 (NINJ2) polymorphisms on susceptibility to coronary heart disease (CHD).

METHODS

We conducted a case-control study with 499 CHD cases and 505 age and gender-matched controls. Five single nucleotide polymorphisms (SNPs) in NINJ2 (rs118050317, rs75750647, rs7307242, rs10849390, and rs11610368) were genotyped by the Agena MassARRAY platform. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression analysis to assess the association of NINJ2 polymorphisms and CHD risk-adjusted for age and gender. What's more, risk genes and molecular functions were screened via protein-protein interaction (PPI) network and functional enrichment analysis.

RESULTS

Rs118050317 in NINJ2 significantly increased CHD risk in people aged more than 60 years and women. Rs118050317 and rs7307242 had strong relationships with hypertension risk in CHD patients. Additionally, rs75750647 exceedingly raised diabetes risk in cases under multiple models, whereas rs10849390 could protect CHD patients from diabetes in allele, homozygote, and additive models. We also observed two blocks in NINJ2. Further interaction network and enrichment analysis showed that NINJ2 played a greater role in the pathogenesis and progression of CHD.

CONCLUSION

Our results suggest that NINJ2 polymorphisms are associated with CHD risk.

Association Between the Composite Cardiovascular Risk and mHealth Use Among Adults in the 2017-2020 Health Information National Trends Survey: Cross-Sectional Study

BACKGROUND

Numerous studies have suggested that the relationship between cardiovascular disease (CVD) risk and the usage of mobile health (mHealth) technology may vary depending on the total number of CVD risk factors present. However, whether higher CVD risk is associated with a greater likelihood of engaging in specific mHealth use among US adults is currently unknown.

OBJECTIVE

We aim to assess the associations between the composite CVD risk and each component of mHealth use among US adults regardless of whether they have a history of CVD or not.

METHODS

This study used cross-sectional data from the 2017 to 2020 Health Information National Trends Survey. The exposure was CVD risk (diabetes, hypertension, smoking, physical inactivity, and overweight or obesity). We defined low, moderate, and high CVD risk as having 0-1, 2-3, and 4-5 CVD risk factors, respectively. The outcome variables of interest were each component of mHealth use, including using mHealth to make health decisions, track health progress, share health information, and discuss health decisions with health providers. We used multivariable logistic regression models to examine the association between CVD risk and mHealth use adjusted for demographic factors.

RESULTS

We included 10,531 adults, with a mean age of 54 (SD 16.2) years. Among the included participants, 50.2% were men, 65.4% were non-Hispanic White, 41.9% used mHealth to make health decisions, 50.8% used mHealth to track health progress toward a health-related goal, 18.3% used mHealth to share health information with health providers, and 37.7% used mHealth to discuss health decisions with health providers (all are weighted percentages). Adults with moderate CVD risk were more likely to use mHealth to share health information with health providers (adjusted odds ratio 1.49, 95% CI 1.24-1.80) and discuss health decisions with health providers (1.22, 95% CI 1.04-1.44) compared to those with low CVD risk. Similarly, having high CVD risk was associated with higher odds of using mHealth to share health information with health providers (2.61, 95% CI 1.93-3.54) and discuss health decisions with health providers (1.56, 95% CI 1.17-2.10) compared to those with low CVD risk. Upon stratifying by age and gender, we observed age and gender disparities in the relationship between CVD risk and the usage of mHealth to discuss health decisions with health providers.

CONCLUSIONS

Adults with a greater number of CVD risk factors were more likely to use mHealth to share health information with health providers and discuss health decisions with health providers. These findings suggest a promising avenue for enhancing health care communication and advancing both primary and secondary prevention efforts related to managing CVD risk factors through the effective usage of mHealth technology.

Down-regulation of JCAD Expression Attenuates Cardiomyocyte Injury by Regulating the Wnt/β-Catenin Pathway

Coronary heart disease (CHD) is one of the most commonly seen cardiovascular conditions across the globe. Junctional cadherin 5 associated (JCAD) protein is found in the intercellular junctions of endothelial cells and linked to cardiovascular diseases. Nonetheless, the influence of JCAD on cardiomyocyte injury caused by CHD is unclear. A model of H2O2-induced H9c2 cell injury was constructed, and JCAD mRNA and protein levels were assessed by qRT-PCR and Western blot. The impacts of JCAD on the proliferation or apoptosis of H9c2 cells were explored by CCK-8 assay, Western blot and TUNEL staining. The effect of JCAD on the inflammatory response and vascular endothelial function of H9c2 cells was detected using ELISA kits. The levels of Wnt/β-catenin pathway-related proteins were assessed by Western blot. H2O2 treatment led to a rise in the levels of JCAD in H9c2 cells. Over-expression of JCAD promoted H2O2-induced cellular injury, leading to notably elevated contents of inflammatory factors, along with vascular endothelial dysfunction. In contrast to over-expression of JCAD, silencing of JCAD attenuated H2O2-induced cellular injury and inhibited apoptosis, inflammatory response and vascular endothelial dysfunction. Notably, JCAD could regulate the Wnt/β-catenin pathway, while DKK-1, Wnt/β-catenin pathway antagonist, counteracted the enhancing impact of JCAD over-expression on H2O2-induced H9c2 cell injury, further confirming that JCAD acts by regulating the Wnt/β-catenin pathway. In summary, over-expression of JCAD promoted H2O2-induced H9c2 cell injury by activating the Wnt/β-catenin pathway, while silencing of JCAD attenuated the H2O2-induced cell injury.

The Use of mHealth in Promoting Therapeutic Adherence: A Scoping Review

Nonadherence to therapy negatively impacts mortality and quality of life and results in suboptimal efficacy of treatment regimens, threats to patient safety, and increased healthcare costs for disease management. Mobile health solutions can offer users instruments that can promote therapeutic adherence. The objective of this review is to investigate the impact mobile health systems have on therapeutic adherence. Specifically, we want to map the main systems used, the functions implemented, and the different methods of adherence detection used. For this purpose, a scoping review was conducted. The following databases were consulted: PubMed, Cochrane Library, EBSCO (including APA PsycINFO, CINAHL Plus with Full Text, ERIC), including English-language studies published in the last 10 years (2012-2022). The main mobile health systems used are as follows: applications, automated messaging, interactive voice response, and mobile video games. The main features implemented to support medication management were as follows: reminders, self-monitoring instruments, educational support, and caregiver involvement. In conclusion, the use of interactive mobile health instruments intended for use by the patient and/or caregiver can improve objectively and subjectively detected therapeutic adherence. The use of these systems in the therapeutic pathway of users, with a special focus on people with comorbidities and in polypharmacy treatment, represents a challenge to improve caregiver health.

Optimising the implementation of digital-supported interventions for the secondary prevention of heart disease: a systematic review using the RE-AIM planning and evaluation framework

BACKGROUND

mHealth technologies are now widely utilised to support the delivery of secondary prevention programs in heart disease. Interventions with mHealth included have shown a similar efficacy and safety to conventional programs with improvements in access and adherence. However, questions remain regarding the successful wider implementation of digital-supported programs. By applying the Reach-Effectiveness-Adoption-Implementation-Maintenance (RE-AIM) framework to a systematic review and meta-analysis, this review aims to evaluate the extent to which these programs report on RE-AIM dimensions and associated indicators.

METHODS

This review extends our previous systematic review and meta-analysis that investigated the effectiveness of digital-supported programs for patients with coronary artery disease. Citation searches were performed on the 27 studies of the systematic review to identify linked publications that reported data for RE-AIM dimensions. All included studies and, where relevant, any additional publications, were coded using an adapted RE-AIM extraction tool. Discrepant codes were discussed amongst reviewers to gain consensus. Data were analysed to assess reporting on indicators related to each of the RE-AIM dimensions, and average overall reporting rates for each dimension were calculated.

RESULTS

Searches found an additional nine publications. Across 36 publications that were linked to the 27 studies, 24 (89%) of the studies were interventions solely delivered at home. The average reporting rates for RE-AIM dimensions were highest for effectiveness (75%) and reach (67%), followed by adoption (54%), implementation (36%) and maintenance (11%). Eleven (46%) studies did not describe relevant characteristics of their participants or of staff involved in the intervention; most studies did not describe unanticipated consequences of the intervention; the ongoing cost of intervention implementation and maintenance; information on intervention fidelity; long-term follow-up outcomes, or program adaptation in other settings.

CONCLUSIONS

Through the application of the RE-AIM framework to a systematic review we found most studies failed to report on key indicators. Failing to report these indicators inhibits the ability to address the enablers and barriers required to achieve optimal intervention implementation in wider settings and populations. Future studies should consider alternative hybrid trial designs to enable reporting of implementation indicators to improve the translation of research evidence into routine practice, with special consideration given to the long-term sustainability of program effects as well as corresponding ongoing costs.

Correlation analysis of central arterial pressure parameters and the severity of atherosclerotic lesions in coronary arteries: A retrospective study

To investigate the correlation between central arterial pressure (CAP) parameters and the severity of atherosclerotic lesions in the coronary arteries, understand the value of CAP in assessing the risk of coronary heart disease (CHD), and provide a theoretical basis for the prevention and treatment of CHD. Between January 2021 and January 2022, 224 patients admitted to our hospital for complete coronary angiography (CAG) were included in this retrospective study. CAP parameters, including central systolic pressure (CSP), diastolic pressure (CDP), and pulse pressure (CPP), and Gensini scores were collected; the association between CAP parameters and the severity of coronary lesions was analyzed using the Pearson correlation coefficient (r) and multivariate regression analysis. CPP was significantly higher in the coronary multi-branch lesion group than in the single-branch lesion group in patients with CHD (P < .05). CSP, CDP, and CPP were significantly higher in the high Gensini score group than in the low Gensini score group for coronary vascular lesions; furthermore, CSP and CPP were significantly higher in the high Gensini score group than in the medium Gensini score group (P < .05). Pearson correlation analysis showed that CSP and CPP were positively and CDP was negatively correlated with the severity of coronary artery lesions in patients with CHD (P < .05). Logistic regression analysis showed that a history of diabetes, CSP, CDP, and CPP were independent risk factors for severe atherosclerotic lesions in the coronary arteries (P < .05). noninvasive CAP-related indices, such as CSP, CDP, and CPP, are independently correlated with and can be used to predict the severity of coronary lesions in patients with CHD, which may be beneficial for guiding clinical diagnosis and treatment.

The interventions to improve medication adherence in coronary heart disease patient: A systematic review

Objective

The clinical outcome and quality of life of CHD patients are greatly influenced by medication adherence. Non-adherence of CHD patients to treatment results in sub-optimal clinical outcomes and increasing costs. This study aims to describe effectiveness of the intervention to improve the medication adherence in CHD patients.

Methods

Systematic review methodology was used in this study. Scopus and PubMed were used to search the relevant article systematically. The outcome measured was medication adherence in coronary heart disease patients.

Results

Final screening was 31 articles that met the inclusion criteria in this study of 788 articles. Selection processes the article used the PRISMA guideline. Most of the articles (15 articles) use interventions that utilize information technology (IT) as known with m-health in the form of text messages, website, and smartphone-based applications in increasing medication adherence in CHD patients. The non m-health interventions developed are in the form of self-efficacy programs, monitoring and education by health workers or care workers, pharmacy care by clinical pharmacists, and the use of drugs in the form of multi-capsules. The results of most intervention with m-health can improve the medication adherence in CHD patient effectively. Education and motivation program by professional health care and multi-capsules also increasing the medication adherence in the intervention control. There was a decrease of medication adherence in some articles with long time follow-up that can be attention for the professional health care to manage the patient adherent.

Conclusion

The medication adherence in CHD patient can be improve by various program. Modification of m-health and non m-health intervention can be resolved to increase the communication, motivation, and knowledge about medication adherence in CHD patients.

Telemedicine: an Effective and Low-Cost Lesson From the COVID-19 Pandemic for the Management of Heart Failure Patients

PURPOSE

The purpose of this review is to explore the benefits and controversies that telemedicine (TM), applied to patients with heart failure (HF), can provide in terms of diagnosis, therapeutic management, and prognosis improvement. During the coronavirus disease 19 (COVID-19) outbreak, TM emerged as the most effective and feasible method available to ensure continuous care for chronic diseases. Among these, HF, characterized by high mortality, morbidity, and the need for frequent visits, may benefit of the TM role. HF patients are affected by frequent exacerbations undergoing a progressive prognosis impoverishment, strongly depending on the disease's management. A precise clinical handling is always required, with a constant optimization of the therapy, a continuous control of risk factors, and a sensitive attention to any change in symptoms, clinical signs, and laboratory tests. In this context, TM has shown to improve therapy adherence and HF: patients' self-care, impacting the prognosis even if specific results are controversial. Major evidence shows that TM may allow an adequate primary prevention, reducing the impact of the main cardiovascular risk factors. TM can also be useful for the secondary prevention, early detecting a likely HF exacerbation before it becomes clinically manifest, thereby lowering the need for hospitalization. Moreover, an optimal up-titration of the therapy and an increase in treatment adherence are feasible by using TM. However, some studies did not show unambiguous results, and uncertainties still remain.

Digital Health Programs to Reduce Readmissions in Coronary Artery Disease: A Systematic Review and Meta-Analysis

Background

The use of mobile health (mHealth, wireless communication devices, and/or software technologies) in health care delivery has increased rapidly in recent years. Their integration into disease management programs (DMPs) has tremendous potential to improve outcomes for patients with coronary artery disease (CAD), yet a more robust evaluation of the evidence is required.

Objectives

The purpose of this study was to undertake a systematic review and meta-analysis of mHealth-enabled DMPs to determine their effectiveness in reducing readmissions and mortality in patients with CAD.

Methods

We systematically searched English language studies from January 1, 2007, to August 3, 2021, in multiple databases. Studies comparing mHealth-enabled DMPs with standard DMPs without mHealth were included if they had a minimum 30-day follow-up for at least one of all-cause or cardiovascular-related mortality, readmissions, or major adverse cardiovascular events.

Results

Of the 3,411 references from our search, 155 full-text studies were assessed for eligibility, and data were extracted from 18 publications. Pooled findings for all-cause readmissions (10 studies, n = 1,514) and cardiac-related readmissions (9 studies, n = 1,009) indicated that mHealth-enabled DMPs reduced all-cause (RR: 0.68; 95% CI: 0.50-0.91) and cardiac-related hospitalizations (RR: 0.55; 95% CI: 0.44-0.68) and emergency department visits (RR: 0.37; 95% CI: 0.26-0.54) compared to DMPs without mHealth. There was no significant reduction for mortality outcomes (RR: 1.72; 95% CI: 0.64-4.64) or major adverse cardiovascular events (RR: 0.68; 95% CI: 0.40-1.15).

Conclusions

DMPs integrated with mHealth should be considered an effective intervention for better outcomes in patients with CAD.

Effects of empowerment education on patients after percutaneous coronary intervention: A meta-analysis and systematic review

BACKGROUND

Empowerment education is a new nursing education model with great significance in the process of chronic disease rehabilitation, and a number of studies have found that it has good benefits for patients after percutaneous coronary intervention (PCI). But there is no meta-analysis on how empowerment education influence the life of patients after PCI.

AIMS

Our study intends to evaluate the impact of empowerment education on the quality of life, cognitive level, anxiety and depression level of patients after PCI.

DESIGN

Systematic review and meta-analysis, following PRISMA guidelines.

METHODS

RevMan5.4 software and R software were used for statistical analysis. Mean difference or standard mean difference was used as effect analysis statistic for continuous variables with 95% confidence intervals.

RESULTS

Six studies met the inclusion criteria, including 641 patients. The Exercise of Self-Care Agency Scale score of the experimental group was higher than that of the control group, with statistically significant difference. Empowerment education could increase the knowledge of coronary heart disease in patients after PCI, but the difference was not statistically significant.

CONCLUSION

Significant effects of empowerment have been found in improving patients' quality of life and self-care ability. Empowerment education could be a safe exercise option in PCI rehabilitation. However, the effect of empowerment on cognitive level for coronary heart disease and the depression needs to carry out more large-sample, multi-center clinical trials.

The WeChat platform-based health education improves health outcomes among patients with stable coronary artery disease

OBJECTIVE

The aim of this study was to evaluate the effect of the WeChat platform-based health education on patients with stable coronary artery disease (CAD) compared with usual care.

METHODS

We conducted a randomized controlled trial that included patients with stable CAD who were admitted to the Bin Hai Wan Central Hospital of Dongguan between January 2020 and December 2020. Participants in the control group received a standard regimen of care. In the WeChat group, the patients were provided with the WeChat platform-based health education by multidisciplinary team members in addition to usual care. The coprimary outcome of the study was the blood pressure, lipid profile, fasting blood glucose, Hamilton Anxiety Scale (HAMA) scores, Hamilton Depression Scale (HAMD) scores and Seattle Angina Questionnaire (SAQ) scores at 12 months, relative to baseline levels.

RESULTS

Between January 2020 and December 2020, 200 eligible CAD patients were randomly assigned to WeChat group (n = 100) or usual care group (n = 100). After 12 months, the number of participants who knew the risk factors, symptoms, diagnostic criteria, management methods and treating target of CAD was significantly larger in the WeChat group than at baseline (P < 0.05) and also larger than the post-intervention level of the control group (P < 0.05). The systolic blood pressure after intervention of the WeChat group significantly decreased compared to those of the control group (132.06 ± 8.87 mmHg vs 140.32 ± 9.42 mmHg; P < 0.05). After intervention, the triglycerides, total cholesterol, and low-density lipoprotein cholesterol of the WeChat group significantly decreased compared to those at baseline and significantly decreased than those in the control group (all P < 0.05). After the intervention, scores of HAMA and HAMD both significantly decreased in the two groups. Moreover, the decreases were more significant in the WeChat group than in the control group (5.78 ± 0.98 vs 8.54 ± 1.24; 6.27 ± 1.03 vs 8.63 ± 1.66; P < 0.05). The SAQ scores of WeChat group were significantly higher than those of the control group in all 5 dimensions at the 1-year follow-up (72.71 ± 10.83 vs 59.32 ± 9.86; 80.01 ± 11.56 vs 61.98 ± 11.02; 76.76 ± 12.64 vs 65.22 ± 10.72; 83.17 ± 13.06 vs 67.01 ± 12.86; 71.82 ± 12.78 vs 55.79 ± 11.90; all P < 0.05).

CONCLUSION

This study showed the high efficacy of the WeChat platform-based health education in improving health outcomes in patients with CAD.

PRACTICE IMPLICATIONS

This study highlighted the potential of social media as a helpful tool for health education among patients with CAD.

Association between monocyte to high-density lipoprotein ratio and coronary heart disease in US adults in the National Health and Nutrition Examination Surveys 2009-2018

BACKGROUND

Monocyte to high-density lipoprotein ratio (MHR) is associated with coronary heart disease (CHD) events. The purpose of this study was to analyze the correlation between MHR and CHD in American adults from 2009 to 2018 in the National Health and Nutrition Examination Surveys (NHANES) database.

METHODS

A total of 25 862 persons in the NHANES from 2009 to 2018 were included in the cross-sectional analysis. The independent variable was MHR and the outcome variable was CHD. MHR was obtained by dividing the number of monocytes by the high-density lipoprotein concentration, and whether it is CHD is obtained through a questionnaire. Univariate analysis, stratified analysis, and a multivariate linear regression model were used to study the correlation between MHR and CHD.

RESULTS

In each multivariate linear regression model, MHR was positively correlated with CHD, and this positive correlation was stable in both men and women [man odds ratio (OR): 1.54; 95% confidence interval (CI), 1.17-2.03; woman OR: 2.21; 95% CI, 1.40-3.50]. Our results show that the association between MHR and CHD was significant until MHR was less than 0.6 (OR: 7.2; 95% CI, 4.0-13.0); however, in cases where MHR was greater than 0.6, the results were negative but not significantly different (OR: 0.6; 95% CI, 0.3-1.2).

CONCLUSION

MHR has a clear association with CHD. Our prediction model and validation model show that MHR is highly predictive and robust as a predictor of CHD, therefore it can play an important role in the prediction of CHD.

Health Techequity: Opportunities for Digital Health Innovations to Improve Equity and Diversity in Cardiovascular Care

Purpose of Review

In this review, we define health equity, disparities, and social determinants of health; the different components of digital health; the barriers to digital health equity; and cardiovascular digital health trials and possible solutions to improve health equity through digital health.

Recent Findings

Digital health interventions show incredible potential to improve cardiovascular diseases by obtaining longitudinal, continuous, and actionable patient data; increasing access to care; and by decreasing delivery barriers and cost. However, certain populations have experienced decreased access to digital health innovations and decreased representation in cardiovascular digital health trials.

Summary

Special efforts will need to be made to expand access to the different elements of digital health, ensuring that the digital divide does not exacerbate health disparities. As the expansion of digital health technologies continues, it is vital to increase representation of minoritized groups in all stages of the process: product development (needs findings and screening, concept generation, product creation, and testing), clinical research (pilot studies, feasibility studies, and randomized control trials), and finally health services deployment.

The impact of dietary education and counselling with a smartphone application on secondary prevention of coronary artery disease: A randomised controlled study (the TeleDiet study)

Objective: In a secondary prevention of coronary artery disease (CAD), nutritional management is an integral part of lifestyle optimisation. However, few studies have investigated the potential of remote nutritional follow-up using digital solutions. This study investigates the effectiveness of a smartphone application for nutrition education and feedback with pictures of meals by a dietitian for patients with CAD. Methods: Sixty participants with CAD were randomised to either a TeleDiet group or a control group. Participants in the TeleDiet group participated in dietary education using a messaging application. The primary outcome was the change of the Mediterranean diet score (MedDietScore). The Nutrition-Score, a modification of the MedDietScore, blood tests (blood lipids, blood glucose and kidney function), body mass index, self-efficacy, medication adherence and health-related quality of life during the observation period were analysed as secondary outcomes. Results: Sixty participants participated in the study. The difference in the MedDietScore in the TeleDiet group was greater than in the control group, but not significant (2.0 [-1.0, 4.0] vs. 0.0 [-3.0, 1.5], p = 0.066). The difference in the Nutrition-Score in the TeleDiet group was significantly greater than in the control group (3.0 [1.0, 3.5] vs. 0.0 [-3.0, 2.0], p = 0.029). Nutrition knowledge of the TeleDiet group improved significantly compared to the control group (1.9 ± 1.7 vs. 0.8 ± 2.1, p = 0.048). Conclusions: A feedback system using a simple messaging application that allows patients with CAD to simply send a picture of their food has a positive effect on nutrition knowledge. It could be a hint for the implementation of the Mediterranean diet.

A Mobile Phone Text Messaging Intervention to Manage Fatigue for People With Multiple Sclerosis, Spinal Cord Injury, and Stroke: Development and Usability Testing

BACKGROUND

Fatigue significantly affects daily functioning in persons with disabilities. Fatigue management can be challenging, and the information provided during routine physician visits to manage fatigue can be overwhelming. One way to address fatigue is to increase knowledge, skills, and confidence for self-management (ie, patient activation). Self-management programs have shown promising effects in targeting fatigue in persons with disabilities. However, satisfaction with self-management programs is low for persons with disabilities, and tailoring interventions to personalized needs has been recommended. SMS text messaging is increasingly being used to implement health behavior change interventions in a person's natural environment. Little has been done to link mobile health approaches with patient activation and self-management to address fatigue in persons with disabilities.

OBJECTIVE

This study aimed to develop and test a mobile phone-based fatigue self-management SMS text messaging intervention targeting patient activation in 3 groups of persons with disabilities: persons with multiple sclerosis, persons who had a stroke, and persons with a spinal cord injury.

METHODS

We used evidence-based resources and input from a consumer advisory board (CAB; composed of 2 participants from each of the 3 disability groups) and a neurologist to develop the intervention. The study was conducted using a 4-step process: development of the initial SMS text messaging library and categorization of the content into 9 content areas, review and modification of the SMS text messages by the neurologist and CAB, integration of the content library into a digital platform, and utility testing by CAB members.

RESULTS

A total of 6 CAB participants rated SMS text messages covering 9 domain areas of fatigue self-management with good clarity (mean ratings=3.5-5.0 out of 5) and relevance (mean ratings=3.2-5.0 out of 5). Overall, SMS text messaging content was reported by CAB participants as helpful, clear, and well suited for a mobile health intervention. The CAB reached consensus on the time of day that SMS text messages should be sent (morning) and their frequency (once per day). This feedback led the research team to narrow down the program to deliver 48 SMS text messages, 1 per day, Monday through Thursday only, a total of 4 SMS text messages per week, over a 12-week period. The final set of SMS text messages was programmed into a digital platform with a predefined delivery schedule. The usability of the intervention was high, with 55 (83%) out of 66 responses endorsing the highest rating.

CONCLUSIONS

This study demonstrates a step-by-step process for developing a fatigue self-management SMS text messaging intervention for persons with disabilities. For this population, whose access to health services is often limited, this intervention provides an alternative delivery model to increase access to fatigue information and deliver content that aligns with the person's needs.

The effect of telemedicine on secondary prevention of atherosclerotic cardiovascular disease: A systematic review and meta-analysis

Aim

The purpose of this systematic review was to evaluate the efficiency of telemedicine on the secondary level of prevention of patients with arteriosclerotic cardiovascular disease (ASCVD), provide evidence for the application of telemedicine in secondary prevention and promote the development of telemedicine in secondary prevention.

Methods

A computer-based search was conducted in MEDLINE, Embase, Pubmed, EBSCO, CINAHL, the Cochrane Library, and Web of Science. Randomized controlled trials regarding the effect of telemedicine on secondary prevention of ASCVD were included from inception to May, 2022. Meta-analysis was used to compare the results of the included studies by RevMan5.4 software. The Cochrane Collaboration bias risk tool was used to perform risk of bias assessment in this study. Outcomes included risk factors, physical activity and exercise, muscle function, exercise compliance, medication adherence, healthy diet, depression and anxiety, self-efficacy, knowledge score, economy, and safety endpoints. Subgroup analysis was carried out for different main intervention measures included in the literature.

Results

A total of 32 randomized clinical studies (n = 10 997 participants) were included in the meta-analysis. Compared with usual secondary prevention (USP) group, participants in telemedicine of secondary prevention (TOSP) group showed significant improvement in some risk factors including BMI (MD -0.87, p = 0.002), SBP (MD -4.09, p = 0.007) and DBP (MD -2.91, p = 0.0002) when they use the telephone as the intervention. In physical activity and exercise, Patients in TOSP showed an improvement in VO2 Peak (mL⋅kg-1⋅min-1) (OR 1.58, p = 0.02), 6MWT (MD 21.41, p = 0.001), GSLTPA score (MD 2.89, p = 0.005). Effects on medication adherence, exercise compliance, muscle function, healthy diet, economy and self-efficacy were synthesized narratively. Patients in TOSP did not show a reduction in knowledge score, depression, anxiety and safety endpoints.

Conclusion

There is a net benefit of secondary prevention supported by telemedicine (especially when using the telephone as an intervention) in patients with ASCVD in the terms of some risk factors, physical activity and exercise. There are still controversies in the improvement of medication adherence, exercise compliance, muscle function, healthy diet, knowledge score, self-efficacy and economy via telemedicine, which is worth exploring. Larger samples size and longer-term follow-ups are needed in future studies.

Real-Time Telerehabilitation in Older Adults With Musculoskeletal Conditions: Systematic Review and Meta-analysis

BACKGROUND

Real-time telerehabilitation (TR) is a new strategy for delivering rehabilitation interventions to older adults with musculoskeletal conditions, to provide continuity to conventional services and mitigate travel-related barriers.

OBJECTIVE

We aimed to examine the effectiveness of treatment delivered via real-time TR services compared to conventional services among older adults with musculoskeletal conditions, in terms of physical performance, treatment adherence, and cost-effectiveness.

METHODS

A literature search of randomized controlled trials (RCTs) published from January 2000 to April 2022 was conducted in six online databases: Cochrane Library, PubMed (ie, MEDLINE), PEDro, ClinicalKey, EBSCO, and ProQuest. The main eligibility criterion for articles was the use of real-time TR among older adults with musculoskeletal conditions to improve physical performance. Two reviewers screened 2108 abstracts and found 10 studies (n=851) that met the eligibility criteria. Quality assessment was based on version 2 of Cochrane's risk-of-bias tool for RCTs, in order to assess the methodological quality of the selected articles. Results were pooled for meta-analyses, based on the primary outcome measures, and were reported as standardized mean differences (SMDs) with 95% CIs. A fixed model was used, and subgroup analysis was performed to check for possible factors influencing TR's effectiveness based on different treatments, controls, and outcome measures.

RESULTS

The search and screening process identified 10 papers that collectively reported on three musculoskeletal conditions in older adults and three types of TR programs. Aggregate results suggested that real-time TR, compared to conventional treatment, was more effective at improving physical performance regarding balance (SMD 0.63, 95% CI 0.36-0.9; I2=58.5%). TR was slightly better than usual care at improving range of motion (SMD 0.28, 95% CI 0.1-0.46; I2=0%) and muscle strength (SMD 0.76, 95% CI 0.32-1.2; I2=59.60%), with moderate to large effects. Subgroup analyses suggested that real-time TR had medium to large effects favoring the use of smartphones or tablets (SMD 0.92, 95% CI 0.56-1.29; I2=45.8%), whereas the use of personal computers (SMD 0.25, 95% CI -0.16 to 0.66; I2=0%) had no effect on improving balance and was comparable to conventional treatment.

CONCLUSIONS

We found that real-time TR improved physical performance in older adults with musculoskeletal conditions, with an effectiveness level equal to that of conventional face-to-face treatment. Therefore, real-time TR services may constitute an alternative strategy for the delivery of rehabilitation services to older adults with musculoskeletal conditions to improve their physical performance. We also observed that the ideal device for delivering TR is the smartphone. Results suggested that the use of smartphones for TR is driven by ease of use among older adults. We encourage future studies in areas related to rehabilitation in older adults, in addition to examination of physical performance outcomes, to gain additional knowledge about comprehensive care.

Feasibility and Potential Effectiveness of a Smartphone Zero-Time Exercise Intervention for Promoting Physical Activity and Fitness in Patients With Coronary Heart Disease: A Pilot Randomized Controlled Trial

BACKGROUND

Zero-time Exercise (ZTEx), a simple strength- and stamina-enhancing physical activity (PA) requiring no extra equipment, can potentially increase PA and fitness. This pilot trial examined the feasibility and potential effectiveness of a smartphone ZTEx intervention to promote PA and fitness in patients with coronary heart disease (CHD).

METHODS

A parallel-group assessor-blinded pilot randomized controlled trial was conducted on Chinese patients with stable coronary heart disease (CHD) in three cardiology clinics. The experimental group received a 15-min brief individual face-to-face session and a 12-week ZTEx instant messaging with 28 picture e-messages and a smartphone ZTEx application (ZTExApp). The control group received the same duration of individual session and number and format of e-messages, but the content was healthy eating and breathing exercise. The feasibility was assessed based on: attrition rate, usage, response rate and perception of the intervention. The outcome evaluation included primary outcome (PA), fitness, exercise self-efficacy and intention, perceived happiness and health, and quality of life. A linear mixed model was used with intention-to-treat analysis adjusting for sex, age and baseline values. A semi-structured interview was conducted to collect feedback from the experiment group.

RESULTS

One hundred thirty-nine patients (mean age 59.8 ± 6.6; 71.2% male) were randomized to the experimental group (n = 70) or control group (n = 69), and 80% (56/70) and 82% (57/69) of patients completed the 12-week follow-up assessment, respectively. The attrition rate was 18.7%. The experimental group reported that ZTEx was feasible to integrate PA into their daily life and appreciated the picture e-messages, and 95% of them sent feedback to us, but only 19.6% (13/70) of the participants entered their PA information into the e-diary of the ZTExApp. The experimental group had a significantly greater increase in time spent walking [mean difference (95% CI): 155.3 (10.1, 300.4), P = 0.04, Cohen's d = 0.34] than the control group.

CONCLUSIONS

This pilot study showed using a brief ZTEx face-to-face session with picture e-messages empowered patients with CHD to integrate PA into daily life. Future definitive trials with a longer follow-up and a more user-friendly ZTExApp interface are necessary to determine the effectiveness of the smartphone ZTEx intervention in enhancing PA and related outcomes.
