Preliminary Effects of a Structured Educational Program in Cardiac Patients at Different Stages of Enrollment in Cardiovascular Rehabilitation

This quasi-experimental study investigated the preliminary effects of a structured education intervention in a pooled sample of cardiovascular rehabilitation (CR) patients in Brazil. Recently enrolled (RE) and long-term enrolled (LTE) patients attended 12 weekly education sessions in addition to three weekly exercise sessions. Patients completed surveys assessing disease-related knowledge, physical activity, food intake, self-efficacy, and health literacy. Functional capacity was assessed by the 6-minutes walking test. All outcomes were assessed at pre-,post-CR, and 6-months follow-up. Bonferroni correction was applied. In total, 69 (69.7%) patients completed all three assessments. There were significant improvements in knowledge pre-to post-test in both subgroups (p < 0.001), and in functional capacity (p ≤ 0.001) and food intake (p ≤ 0.001) pre-to post-test in the RE subgroup. Post-test knowledge was correlated to physical activity, functional capacity and health literacy. This preliminary study suggests the importance of structured education for CR patients. A larger study using a randomized controlled design is needed to determine efficacy.

Knowledge, Attitude, and Practice of Physiotherapists about Cardiac Rehabilitation Program Adherence among Patients Discharged from the Hospital after Cardiac Surgery in India

Background

In most settings, patients receive phase 1 cardiac rehabilitation in CTVS ICU at the hospital, but there are several barriers to follow-up after patients are discharged from the hospital. Physiotherapists play an important role in the enrolment and continuation of cardiac rehabilitation. Thus, we aim to study the knowledge, attitude, and practice of physiotherapists about CR program adherence among patients discharged from the hospital after cardiac surgery.

Objectives

(i) To study the knowledge of physiotherapists about the importance of cardiac rehabilitation after discharge; (ii) to know the attitude of physiotherapists towards cardiac surgery patients after discharge; and (iii) to know what approach various centres are applying for patients after discharge to ensure adherence to cardiac rehabilitation.

Methods

A questionnaire was developed with reference to the objectives of the study, which was answered by a total of 127 physiotherapists.

Results

The overall response rate was 42.3%; nearly 35.4% of the participants indicated that they knew a lot about CR, while 5.5% said they knew very little. Regarding the program's content, 36.2% of participants reported having a medium degree of awareness of the diverse CR components, while 8.6% reported having very little knowledge of them. Only about one-third, 35.7% stated that CR in India is effective and 95% believed that CR will have an added value for the country. Approximately 80% of respondents thought that it would be challenging for a physiotherapist to recommend patients to a CR in the nation. Nearly 35% of respondents believed that they, "themselves as physios," needed to commence CR, and slightly less than 70% thought that doctors were required to choose and refer the patients when asked who should take the initiative to start this kind of programme in the country. A little over 40% of respondents said that insurance firms are also involved in starting a CR programme.

Conclusion

Physiotherapists have good knowledge of cardiac rehabilitation. However, their attitude and practice towards adherence to exercise protocols are confounded by various clinician- and patient-level factors.

Cost-Effectiveness of Cardiac Rehabilitation in Older Adults With Coronary Heart Disease

PURPOSE

While cardiac rehabilitation (CR) is recommended and effective following acute cardiac events, it remains underutilized, particularly in older adults. A study of 601 099 Medicare beneficiaries ≥65 yr hospitalized for coronary heart disease compared 5-yr mortality in users and nonusers of CR. Using instrumental variables (IV), CR improved mortality by 8.0% ( P < .001). A validation analysis based on 70 040 propensity-based (PB) matched pairs gave a similar gain (8.3%, P < .0001). The present cost-effectiveness analysis builds on these mortality results.

METHODS

Using the framework of the Second Panel on Cost-Effectiveness Analysis, we calculated the incremental cost-effectiveness ratio (ICER) gained due to CR. We accessed the costs from this cohort, inflated to 2022 prices, and assessed the relationship of quality-adjusted life years (QALY) to life years from a systematic review. We estimated the ICER of CR by modeling lifetime costs and QALY from national life tables using IV and PB.

RESULTS

Using IV, CR added 1.344 QALY (95% CI, 0.543-2.144) and $40 472 in costs over the remaining lifetimes of participants. The ICER was $30 188 (95% CI, $18 175-$74 484)/QALY over their lifetimes. Using the PB analysis, the corresponding lifetime values were 2.018 (95% CI, 1.001-3.035) QALY, $66 590, and an ICER of $32 996 (95% CI, $21 942-$66 494)/QALY.

CONCLUSIONS

Cardiac rehabilitation was highly cost-effective using guidelines established by the World Health Organization and the US Department of Health and Human Services. The favorable clinical effectiveness and cost-effectiveness of CR, along with low use by Medicare beneficiaries, support the need to increase CR use.

Effects of perioperative exercise on cardiorespiratory endurance in children with congenital heart disease in plateau areas after surgical repair

We aimed to explore the effects of perioperative exercise on cardiorespiratory endurance in children with congenital heart disease (CHD) in plateau areas after surgical repair. Fifty children with CHD in the plateau admitted to our hospital were randomly divided into the exercise and control groups. The exercise group received a perioperative exercise intervention beginning within 24 h postoperatively, while the control group received routine nursing and treatment alone. To assess the 6 min walk distance (6MWD) at baseline and at end of intervention, children participated in a 6-min walk test before cardiac repair and at 1 week after general ward transfer. A subset of children in the study underwent the cardiopulmonary exercise test pre-operatively. The 6MWD of children with CHD at baseline was positively correlated with the peak oxygen uptake pre-operatively. No significant difference was reported in the preoperative baseline data of both groups. The 6MWD of the exercise group was significantly higher than that of the control group. Early exercise therapy after cardiac repair could significantly improve the cardiorespiratory endurance and exercise capacity of children with CHD in plateau areas.

Characteristics and correlates of disease-related knowledge and exercise self-efficacy among cardiac patients attending virtual cardiac rehabilitation during the first COVID-19 lockdown in Peru

BACKGROUND

Government responses and restrictions due to the COVID-19 pandemic (e.g., limits to non-urgent health care services, including non-urgent outpatient appointments) led to the suspension of center-based (in-person) cardiac rehabilitation (CR), with many programs switching to virtual delivery. This study aimed to understand the characteristics and correlates of disease-related knowledge and exercise self-efficacy in a group of patients attending a virtual CR program during the first COVID-19 lockdown in Peru.

METHODS

In this prospective observational study, 240 patients receiving virtual CR care (exercise instructions and patient education) between August/2020 and December/2021 completed questionnaires pre- and post-CR assessing disease-related knowledge (CADE-Q SV questionnaire) and self-efficacy (SE; Bandura's Exercise SE scale). Paired t tests were used to investigate changes pre/post-CR and Pearson correlation coefficients were used to determine the association between knowledge/SE and patients' characteristics.

RESULTS

Participants were mainly comprised of men, with a cardiac diagnosis of stable coronary artery disease, who underwent percutaneous coronary intervention or had a known diagnosis of hypertension and with at least one cardiovascular risk factor (95.8%). Mean total knowledge scores improved significantly at post-CR (12.9 ± 2.4 to 15.6 ± 2.0/20; p<0.001), as well as in 4/5 knowledge areas (cardiovascular risk factors, exercise, nutrition, and psychosocial risk; p<0.001). Mean SE scores improved significantly at post-CR (1.9 ± 0.9 to 3.0 ± 0.9/5; p = 0.01). Post-CR knowledge and SE were significantly correlated with cardiac diagnosis and surgical procedures (r = 0.17, p = 0.02 and r = 0.27, p = 0.02, respectively).

CONCLUSIONS

The virtual CR program improved disease-related knowledge and SE of cardiac patients during the first months of the COVID-19 pandemic. Post-CR outcomes were correlated with cardiac diagnosis and surgical procedures and more research with other characteristics is warrantied.

The effects of a 5-year physical activity on prescription (PAP) intervention in patients with metabolic risk factors

BACKGROUND

Increased physical activity (PA) has positive effects on health and longevity. In Swedish healthcare, the physical activity on prescription (PAP) method reportedly increases patients' PA levels for up to 12 months, but long-term follow ups are lacking. As it remains difficult to maintain lifestyle changes, our aim was to evaluate adherence and clinical effects at a 5-year follow-up of PAP treatment in primary healthcare.

METHODS

This longitudinal, prospective cohort study included 444 patients, (56% female), aged 27-85 years, with at least one metabolic risk factor. Participants were offered PAP by nurses or physiotherapists. The PAP intervention included an individualised dialogue, a PA recommendation by written prescription, and individually adjusted follow-up over 5 years, according to the Swedish PAP model. Patient PA level, metabolic risk factors, and health related quality of life (HRQoL) were measured at baseline and at the 6-month, 1.5-year, 2.5-year, 3.5-year, and 5-year follow-ups. Estimated latent growth curves were used to examine levels and rates of change in the outcomes.

RESULTS

The study dropout rate was 52%, with 215 of 444 patients completing the 5-year follow-up. At follow-up, the mean PA level had increased by 730 MET-minutes per week or 3 hours of moderate-intensity PA/week when compared to baseline. During the 5-year intervention, we observed significant positive changes (p ≤ 0.05) in 9 of 11 metabolic risk factors and HRQoL parameters: body mass index, waist circumference, systolic and diastolic blood pressure, fasting plasma glucose, triglycerides, cholesterol, high-density lipoprotein, and mental component summary.

CONCLUSION

This first evaluation of a 5-year PAP intervention in primary care demonstrated positive long-term (5 years) effects regarding PA level, metabolic health, and HRQoL. The recorded long-term adherence was ~50%, which is in line with medical treatment. Despite limitations, PAP can have long-term effects in an ordinary primary care setting.

Why Do so Few People with Heart Failure Receive Cardiac Rehabilitation?

Many people with heart failure do not receive cardiac rehabilitation despite a strong evidence base attesting to its effectiveness, and national and international guideline recommendations. A more holistic approach to heart failure rehabilitation is proposed as an alternative to the predominant focus on exercise, emphasising the important role of education and psychosocial support, and acknowledging that this depends on patient need, choice and preference. An individualised, needs-led approach, exploiting the latest digital technologies when appropriate, may help fill existing gaps, improve access, uptake and completion, and ensure optimal health and wellbeing for people with heart failure and their families. Exercise, education, lifestyle change and psychosocial support should, as core elements, unless contraindicated due to medical reasons, be offered routinely to people with heart failure, but tailored to individual circumstances, such as with regard to age and frailty, and possibly for recipients of cardiac implantable electronic devices or left ventricular assist devices.

Objectively measured preoperative physical activity and sedentary behaviour among Finnish patients scheduled for elective cardiac procedures: baseline results from randomized controlled trial

Background

We investigated preoperative physical activity (PA) and sedentary behaviour (SB) in patients scheduled for elective cardiac procedures and compared them with population-based sample of Finnish adults.

Methods

Cardiac patients (n = 139) undergoing cardiac operations carried a triaxial accelerometer for seven days during the month before the procedure. Patients were categorised into four groups according to the procedure: percutaneous coronary intervention or coronary angiography (PCI-CA), coronary artery bypass grafting (CABG), aortic valve replacement (AVR) and mitral valve surgery (MVS). The raw accelerometer data was analyzed with dedicated algorithms to determine metabolic equivalents (METs, 3.5 mL/kg/min of oxygen consumption) of PA. The intensity of PA was divided into two categories: light (LPA, 1.5–2.9 METs) and moderate-to-vigorous (MVPA, ≥ 3.0 METs), while SB represented intensity < 1.5 MET without movements. SB and PA were described as daily means and accumulation from different bout lengths. Daily standing, steps and mean and peak MET-values were calculated. The results were compared between the patient groups and against the reference group from a population-based study FinFit2017.

Results

Cardiac patients had fewer daily steps than the FinFit population (p = 0.01), and less SB accumulating from < 20 min bouts (p = 0.002) but more from 20 to 60 min bouts (p = 0.002). Particularly, CABG group had less daily MVPA (p = 0.002) and MVPA accumulating from > 10 min bouts (p < 0.001) than the FinFit population.

Conclusions

We found large differences in PA and SB between the patient groups and the FitFit population, CABG group having the worst activity profile. Also, the variation within the patient groups was wide, which should be considered to individualise the rehabilitation programs postoperatively.

Potential Cost Savings for the Healthcare System by Physical Activity in Different Chronic Diseases: A Pilot Study in the Veneto Region of Italy

Background: Sedentary behaviour (SB) and physical inactivity (PI) are associated with an increased risk of chronic diseases and a significant economic burden. This pilot study aims to estimate the possible cost savings for the Veneto Regional Health Service (Italy) due to a population-based physical activity (PA) intervention. Methods: The PA-related cost-savings were assessed for four chronic diseases in the whole and sedentary populations of the Veneto region. The SB and PA epidemiological data, regarding an additional percutaneous coronary intervention in coronary artery disease, hospitalizations in chronic obstructive pulmonary disease, surgery for colorectal cancer, and femur fracture, were obtained from national and regional administrative sources. A relative risk reduction, due to PA, was obtained from the recent literature. The annual healthcare costs were estimated using the regional diagnosis-related group tariffs. Results: The annual estimated cost-savings for the regional healthcare service related to these four outcomes: an amount between EUR 5,310,179 (if a conservative analysis was performed) and EUR 17,411,317. Conclusion: By a downward estimate, regarding the direct healthcare costs, PA interventions could lead to important cost-savings in the Veneto region. The savings would be greater when considering the cross-sectional impact on other healthcare costs, comorbidities, and indirect costs.

A Social-Ecological Perspective of the Perceived Barriers and Facilitators to Virtual Education in Cardiac Rehabilitation: A MIXED-METHODS APPROACH

PURPOSE

This study explored the perceived barriers and facilitators to participation in patients who did and did not attend virtual cardiac rehabilitation (CR) education sessions.

METHODS

A mixed-methods approach was used. Virtual patient education was delivered during the coronavirus-19 pandemic. Phase 1 included a cross-sectional online survey completed by individuals who did and did not participate in these sessions. For phase 2, six virtual focus group sessions were conducted using the social-ecological framework to guide thematic analysis and interpretation of findings.

RESULTS

Overall, 106 online surveys were completed; 60 (57%) attended Cardiac College Learn Online (CCLO) sessions only, one (1%) Women with Heart Online (WwHO) only, 21 (20%) attended both, and 24 (22%) did not attend virtual sessions. Half of the participants who attended virtual sessions viewed between one and four sessions. Most participants were from Canada (95%) and included the Toronto Rehabilitation Institute/Toronto Western Hospital centers (76%). Focus group findings revealed six overarching themes: Intrapersonal (mixed emotions/feelings; personal learning preferences); Interpersonal (desire for warmth of human contact and interaction); Institutional (the importance of external endorsement of sessions); and Environmental (technology; perceived facilitators and barriers).

CONCLUSION

These findings highlight the unprecedented situation that patients and CR programs are facing during the pandemic. Virtual patient education may be more accessible, convenient, and responsive to the complex needs of these CR participants.

Knowledge, attitudes, and practices of cardiopulmonary rehabilitation among physiotherapists in Lebanon

Background

Insufficient physical activity is one of the leading mortality risks worldwide for cardiovascular and pulmonary diseases. Physiotherapists (PT) are core healthcare professionals who play a major role in the prevention of disease complications and in inspiring a healthy lifestyle. To identify challenges in the promotion of cardiopulmonary rehabilitation (CR) in Lebanon, a survey was conducted among PT and physiotherapy students. The aim was to assess the knowledge, attitudes, and practices of CR in Lebanon.

Results

The response rate was 46.1% (N = 322). Results show that 24.5% of respondents have good to excellent knowledge about CR. More than 60% of the respondents indicate possible barriers to starting a CR program, and one of two respondents identify the absence of skills as a main barrier. Findings highlight the importance of the role of PT as a mediator to increase a healthy lifestyle among patients and to promote the prevention of cardiovascular diseases and pulmonary diseases in the country.

Conclusions and recommendations

Our results support the evidence and clinical guidelines that PT play a major role by increasing the participation of patients in CR. A cost-effective CR program needs to be covered by the private and public system in Lebanon.

Current role and future perspectives of cardiac rehabilitation in coronary heart disease

Ischaemic heart disease (IHD) is a major cause of morbidity and mortality worldwide. While there have been major advances in this field, these patients are still a higher risk subgroup. As such, strategies to mitigate risk and tailor secondary prevention measures are of the utmost relevance. Cardiac rehabilitation (CR), encompassing several domains including exercise training, cardiovascular risk factor optimization, nutritional and psychological assessments, as well as other ancillary interventions has shown to be one of the pillars in the contemporary management of patients with IHD. Indeed, CR is associated with several benefits in this population, ranging from functional capacity to improvements in outcomes. Whilst this, there are still several issues concerning the optimal application of CR which are still not fully ascertained, such as lack of referral and completion, as well as questions related to programme design (particularly among patients with multiple comorbidities). In this review, we aim at presenting a pragmatic overview on the current role of CR in the management of individuals with IHD, while also discussing some of the caveats in the current data, as well as future concepts which could help improve the uptake and personalization of this pivotal time-tested intervention.

Application Effect of Meticulous Nursing on Community Elderly Patients with Coronary Heart Disease under the Background of Medical Treatment Partnerships

Objective

To explore the application effect of meticulous nursing on community elderly patients with coronary heart disease (CHD) under the background of medical treatment partnerships.

Methods

A total of 96 elderly CHD patients treated in the community from July 2019 to July 2020 were selected as the research objects and divided into the experimental group (n = 48) and control group (n = 48) by the medical personnel according to their admission order. Clinical routine nursing was performed to the patients in the control group, and meticulous nursing under the background of medical treatment partnerships was conducted to the patients in the experimental group, so as to evaluate their quality of life (QOL) and self-care agency after intervention by the Chinese Questionnaire on Quality of Life in Patients with Cardiovascular Disease (CQQC) and Exercise of Self-Care Agency (ESCA) scale.

Results

Compared with the control group after intervention, the patients in the experimental group presented significantly higher ESCA scores, HHI scores, and CQQC scores and longer 6 min walking distance (P < 0.001) and remarkably lower POMS scores (P < 0.001) and had obviously higher numbers of cases with various health-related actions (P < 0.05).

Conclusion

Meticulous nursing under the background of medical treatment partnerships is a reliable method for improving the QOL and mood state of community elderly CHD patients, which greatly promotes patients' self-care agency and expectation. Further research will be conducive to establishing a better solution for patients.

A Focus Group Study to Understand the Perspectives of Physiotherapists on Barriers and Facilitators to Advancing Rehabilitation in Low-Resource and Conflict Settings

Physiotherapy as a health profession is continuously evolving in high-income countries (HIC). The highest burden of disease globally, however, is in low-resource and conflict contexts (LR-CC), resulting in unmet rehabilitation needs. Rehabilitation service models from HIC often face challenges when applied to the fragile health systems of LR-CC. It is important to engage rehabilitation experts living and working in LR-CC to guide service development. This study aims to understand physiotherapists' views and perspectives of current rehabilitation services, of how these services can be strengthened over the next 10 years and of the role of physiotherapy within this development. Focus group discussions (FGDs) were conducted with 31 physiotherapists from 18 LR-CC using English as a common language. Audio recordings were transcribed verbatim. Data analysis was guided by thematic analysis. Participants provided deep insights into the complexity of developing rehabilitation services within fragile health systems. Participants agreed that physiotherapy lacked recognition and resources to be utilised effectively. Interacting themes as crucial prerequisites for strengthening the sector included (1) significance of context, (2) professional identity, and (3) professionalisation supported by workforce development and advocacy. These results are an important evidence base for informing the development of rehabilitation programmes in LR-CC and for future research.

Strategies for Promotion of a Healthy Lifestyle in Clinical Settings: Pillars of Ideal Cardiovascular Health: A Science Advisory From the American Heart Association

Engagement in healthy lifestyle behaviors is suboptimal. The vast majority of the US population does not meet current recommendations. A healthy lifestyle is defined by consuming a healthy dietary pattern, engaging in regular physical activity, avoiding exposure to tobacco products, habitually attaining adequate amounts of sleep, and managing stress levels. For all these health behaviors there are well-established guidelines; however, promotion in clinical settings can be challenging. It is critical to overcome these challenges because greater promotion of heathy lifestyle practices in clinical settings effectively motivates and initiates patient behavior change. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with requisite attention to the demands of clinical settings. In this science advisory, we present strategies, based on the 5A Model, that clinicians and other health care professionals can use for efficient lifestyle-related behavior change counseling in patients at all levels of cardiovascular disease risk at every visit. In addition, we discuss the underlying role of psychological health and well-being in lifestyle-related behavior change counseling, and how clinicians can leverage health technologies when providing brief patient-centered counseling. Greater attention to healthy lifestyle behaviors during routine clinician visits will contribute to promoting cardiovascular health.

Speed controller-based fuzzy logic for a biosignal-feedbacked cycloergometer

Nowadays, fuzzy-logic systems are implemented to control machinery or processes that previously required human manipulation. The main objective of this research is to propose a controller based on fuzzy-logic that uses bio-signals for decision making. The study presents the implementation of a fuzzy-speed controller for a therapeutic machine called cycloergometer. It is used in patients who require rehabilitation therapy to improve their mobility in the lower body or to increase their relaxation or flexibility. Basic controllers have been developed where the speed is decided through a user interface, and the therapist must constantly increase or decrease the speed according to the condition of the patient. In this paper, the speed of the therapy equipment is adjusted using the heart rate of the patient. In this way, a bio-signal is used to determine whether a person is tired or relaxed. Therefore, a mechanism is obtained that is not subject to the visual criteria of the therapist. A detailed review of the literature illustrates that one of the main limitations of electroencephalography and electromyography recordings is the low signal-to-noise ratio and the fact that the signals captured at the electrodes are a mixture of sources that cannot be observed directly with noninvasive methods. Therefore, it was decided to work with electrocardiogram-based signals for better robustness of the proposed system. The controller output is a voltage signal in PWM, which is determined by the membership and error functions. The behavior of the implemented controller is validated by different experimental tests based on the increase and decrease of the simulated and real heart rate of a patient. Finally, the results obtained and the possible areas of opportunity for the proposed design are discussed.

Long-term outcomes after revascularization and medical therapy in premature coronary artery disease for cost-effectiveness study: A systematic review protocol

BACKGROUND

The long-term outcomes are important concepts for cost-effectiveness analysis in patients with premature coronary artery disease after revascularization (coronary artery bypass grafting [CABG] and percutaneous coronary intervention [PCI]) and medical therapy (MT). The finding of this study will be used to calculate the events probabilities for cost-effectiveness study.

METHODS AND ANALYSIS

This systematic review will use studies in which patients age must be 18-60 years in eligible studies that obtained from PubMed, Web of Science, Scopus, and Embase. We will assess the long-term outcomes after CABG, PCI, and MT by random-effects meta-analysis and effects will be shown by risk ratio. We will ascertain the probabilities of adverse events during certain periods and then outcomes will compare separately based on specific characteristics.

CONCLUSION

This study will provide information related to outcomes of CABG, PCI, and MT in patients with premature coronary artery disease. Doing this systematic review is valuable from clinically and economically aspects such as cost-effectiveness and cost-utility analysis.

Sex differences in physical and mental health following high-intensity interval training in adults with cardiovascular disease who completed cardiac rehabilitation

This pre-post study examined sex-differences in peak aerobic power (V̇O2peak) and physical- and mental-health outcomes in adults with cardiovascular disease who completed high-intensity interval training (HIIT)-based cardiac rehabilitation. HIIT consisted of 25 minutes of alternating higher- (4×4 minutes 85-95% heart rate peak (HRpeak)) and lower- (3×3 minutes 60-70% HRpeak) intensity intervals twice weekly for 10 weeks. V̇O2peak estimated from a graded exercise test using the American College of Sports Medicine equation, body mass index (BMI), waist circumference, blood pressure, blood biomarkers and anxiety and depression were assessed at baseline and follow-up. Linear mixed-effects models for repeated measures were performed to examine differences over time between sexes. Of 140 participants (mean ± standard deviation: 58 ± 9 years), 40 were female. Improvements in V̇O2peak did not differ between sexes (interaction: p = 0.273, females: 28.4 ± 6.4 to 30.9 ± 7.6; males: 34.3 ± 6.3 to 37.4 ± 6.0 mL/kg/min). None of the time by sex interactions were significant. Significant main effects of time showed reductions in waist circumference, triglycerides, low-density lipoprotein (LDL), total cholesterol (TC)/high-density lipoprotein (HDL) and anxiety, and increases in V̇O2peak and HDL from baseline to follow-up. Significant main effects of sex revealed smaller V̇O2peak, BMI and waist circumference, and higher LDL, TC and HDL in females than males. HIIT led to similar improvements in estimated V̇O2peak (females: 8.8%, males: 9.0%) and additional health outcomes between sexes. Novelty: HIIT-based cardiac rehabilitation led to similar improvements in estimated V̇O2peak and other physical and mental health outcomes between sexes. The number of sessions attended was high (>70%) and did not differ by sex. Both sexes showed good compliance with the exercise protocol (HR target).

Downhill hiking improves low-grade inflammation, triglycerides, body weight and glucose tolerance

Exercise is a well-established tool for cardiovascular risk reduction. Particularly eccentric exercise, which essentially means walking downwards could favour more people becoming physically active. With the present controlled study, we tested the hypothesis that eccentric exercise can improve insulin sensitivity, triglyceride handling, body mass index, glucose tolerance and inflammation. We allocated 127 healthy sedentary individuals to one of two groups: (i) an active group of 102 individuals walking downwards a predefined route three to five times per week over two months, covering a difference in altitude of 540 m; for the upward route a cable car was used, for which adherence was recorded electronically and (ii) a matched control group of 25 individuals who stayed sedentary. Fasting and postprandial metabolic profiles were obtained at baseline and after two months. Compared to baseline, eccentric exercise significantly improved HOMA insulin resistance (1.94 ± 1.65 vs. 1.71 ± 1.36 (µU⁻¹ ml) × ((mmol/l)⁻¹22.5); p = 0.038) and resulted in a decrease in fasting glucose (97 ± 15 vs. 94 ± 9 mg dl⁻¹; p = 0.025) and glucose tolerance (238 ± 50 vs. 217 ± 47 mg dl⁻¹ h⁻¹; p < 0.001), whereas these parameters did not change significantly in the control group. Eccentric exercise significantly improved triglyceride tolerance (1923 ± 1295 vs. 1670 ± 1085 mg dl⁻¹ h⁻¹; p = 0.003), whereas triglyceride tolerance remained unchanged in the control group (p = 0.819). Furthermore, body mass index (27.7 ± 4.3 vs. 27.4 ± 4.3 kg m⁻²; p = 0.003) and C-reactive protein (0.27 ± 0.42 vs. 0.23 ± 0.25 mg dl⁻¹; p = 0.031) were significantly lowered in the eccentric exercise group but not in the control group. Downhill walking, a type of exercise is a promising unusual exercise modality with favorable effects on body mass index, insulin action, on postprandial glucose and triglyceride handling and on C-reactive protein.

Establishing a process to translate and adapt health education materials for natives and immigrants: The case of Mandarin adaptations of cardiac rehabilitation education

BACKGROUND

Cardiac rehabilitation (CR) is a proven model of secondary prevention in which patient education is a core component.

OBJECTIVES

to translate and culturally-adapt CR patient education for Mandarin-speaking patients living in China as well as immigrants, and offer recommendation for best practices in adaptation for both.

METHODS

these steps were undertaken in China and Canada: (1) preparation; (2) translation and adaptation; (3) review by healthcare providers based on PEMAT-P; (4) think-aloud review by patients; and (5) finalization.

RESULTS

Two independent Mandarin translations were undertaken using best practices: one domestic (China) and one international (immigrants). Input by 23 experts instigated revisions. Experts rated the language and content as culturally-appropriate, and perceived the materials would benefit their patients. A revised version was then administered to 36 patients, based on which a few edits were made to optimize understandability.

CONCLUSIONS

some important differences emerged between translations adapted for native versus immigrant settings.

Impacts of the COVID-19 Pandemic on Cardiac Rehabilitation Delivery around the World

Background

We investigated impacts of COVID-19 on cardiac rehabilitation (CR) delivery around the globe, including virtual delivery, as well as effects on providers and patients.

Methods

In this cross-sectional study, a piloted survey was administered to CR programs globally via REDCap from April to June 2020. The 50 members of the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) and personal contacts facilitated program identification.

Results

Overall, 1062 (18.3% program response rate) responses were received from 70/111 (63.1% country response rate) countries in the world with existent CR programs. Of these, 367 (49.1%) programs reported they had stopped CR delivery, and 203 (27.1%) stopped temporarily (mean = 8.3 ± 2.8 weeks). Alternative models were delivered in 322 (39.7%) programs, primarily through low-tech modes (n = 226,19.3%). Furthermore, 353 (30.2%) respondents were re-deployed, and 276 (37.3%) felt the need to work due to fear of losing their job, despite the perceived risk of contracting COVID-19 (mean = 30.0% ± 27.4/100). Also, 266 (22.5%) reported anxiety, 241(20.4%) were concerned about exposing their family, 113 (9.7%) reported increased workload to transition to remote delivery, and 105 (9.0%) were juggling caregiving responsibilities during business hours. Patients were often contacting staff regarding grocery shopping for heart-healthy foods (n = 333, 28.4%), how to use technology to interact with the program (n = 329, 27.9%), having to stop their exercise because they have no place to exercise (n = 303, 25.7%), and their risk of death from COVID-19 due to pre-existing cardiovascular disease (n = 249, 21.2%). Respondents perceived staff (n = 488, 41.3%) and patient (n = 453, 38.6%) personal protective equipment, as well as COVID-19 screening (n = 414, 35.2%), and testing (n = 411, 35.0%) as paramount to in-person service resumption.

Conclusion

Given the estimated number of CR programs globally, these results suggest approximately 4400 CR programs globally have ceased or temporarily stopped service delivery. Those that remain open are implementing new technologies to ensure their patients receive CR safely, despite the challenges.

Highlights

- COVID-19 has impacted cardiac rehabilitation (CR) delivery around the globe.- In this cross-sectional study, a survey was completed by 1062 (18.3%) CR programs from 70 (63.1%) countries.- The pandemic has resulted in at least temporary cessation of ~75% of CR programs, with others ceasing initiation of new patients, reducing components delivered, and/or changing of mode delivery with little opportunity for planning and training.- There is also significant psychosocial and economic impact on CR providers.- Alternative CR model (e.g., home-based, virtual) reimbursement advocacy is needed, to ensure safe, accessible secondary prevention delivery.

Effects of Teaching Resourcefulness in Patients with Coronary Heart Disease

This cluster randomized controlled trial aimed to investigate the effects of an intervention to teach resourcefulness on depression and coping style of patients with coronary heart disease (CHD). A convenience sample of 72 patients in community settings took part. Participants in the intervention group (n = 36) received an 8-week intervention based on the concept of resourcefulness, plus routine health education. Participants in the control group (n = 36) received routine health education only. After the intervention, participants in the intervention group had significantly higher scores on resourcefulness and coping styles, and lower scores on depression than those in the control group (both ps < .001). The findings suggest that a well-developed intervention to teach resourcefulness could help patients with CHD to be more resourceful, improve their level of depression, and choose more effective strategies to cope with stress.

Translation and evaluation of a comprehensive educational program for cardiac rehabilitation patients in Latin America: A multi-national, longitudinal study

OBJECTIVES

To translate, cross-culturally adapt and validate a comprehensive evidence- and theoretically-based CR education intervention in Latin America.

METHODS

First, best practices in translation and cross-cultural adaptation were applied through 6 steps. Then, the Spanish version was delivered to CR participants from programs in Colombia, Costa Rica and Peru for validation, such that the evaluation was pre-post, uncontrolled, pragmatic, observational, and prospective in design. Participants completed surveys assessing knowledge, health literacy, self-efficacy, and health behaviours. All outcomes were assessed pre-, and post-CR, as well as 6 months after CR completion.

RESULTS

After translation of the patient guide from English to Spanish, 5 of the 9 booklets were culturally adapted. Two-hundred and forty-nine patients consented to participate, of which 184 (74 %) completed post-CR, and 121 (48 %) completed final assessments. There was a significant improvement in disease-related knowledge pre- to post-CR, as well as in health literacy, self-efficacy, and health behaviours (all p < 0.05). These gains were sustained 6 months post-program. With adjustment, CR attendance (i.e., exposure to the education) was associated with greater post-CR knowledge (ß = 0.026; p = 0.01).

CONCLUSION

A patient education intervention for CR patients in Latin America has been validated, and wider implementation is warranted.

PRACTICE IMPLICATIONS

Application of this first-ever validated CR education program for Spanish-speaking settings may result in secondary prevention.

The Role of Prevention in Reducing the Economic Impact of ME/CFS in Europe: A Report from the Socioeconomics Working Group of the European Network on ME/CFS (EUROMENE)

This report addresses the extent to which there may be scope for preventive programmes for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), and, if so, what economic benefits may accrue from the implementation of such programmes. We consider the economic case for prevention programmes, whether there is scope for preventive programmes for ME/CFS, and what are the health and economic benefits to be derived from the implementation of such programmes. We conclude that there is little scope for primary prevention programmes, given that ME/CFS is attributable to a combination of host and environmental risk factors, with host factors appearing to be most prominent, and that there are few identified modifiable risk factors that could be the focus of such programmes. The exception is in the use of agricultural chemicals, particularly organophosphates, where there is scope for intervention, and where Europe-wide programmes of health education to encourage safe use would be beneficial. There is a need for more research on risk factors for ME/CFS to establish a basis for the development of primary prevention programmes, particularly in respect of occupational risk factors. Secondary prevention offers the greatest scope for intervention, to minimise diagnostic delays associated with prolonged illness, increased severity, and increased costs.

Efficacy, Feasibility, Adherence, and Cost Effectiveness of a mHealth Telerehabilitation Program in Low Risk Cardiac Patients: A Study Protocol

Individual and group cardiac rehabilitation (CR) programs reduce cardiovascular morbidity and mortality by reducing recurrent events, improving risk factors, aiding compliance with drug treatment, and improving quality of life through physical activity and education. Home-based programs are equally effective in improving exercise capacity, risk factors, mortality, and health-related quality of life outcomes compared to hospital-based intervention. Cardio-telerehabilitation (CTR) programs are a supplement or an alternative to hospital rehabilitation programs providing similar benefits to usual hospital and home care. Despite this statement, implementation in the public and private healthcare environment is still scarce and limited. The main objective of this research was to evaluate the efficacy, feasibility, and adherence of a personalized eight-week mHealth telerehabilitation program in low-risk cardiac patients in the hospital of Melilla (Spain). The secondary aims were to investigate patient satisfaction, identify barriers of implementation and adverse events, and assess cost-effectiveness from a health system perspective. A study protocol for a single center prospective controlled trial was conducted at the Regional Hospital of Melilla (Spain), with a sample size of (n = 30) patients with a diagnosis of low-risk CVD with class I heart failure according to NYHA (New York Heart Association). Outcomes of this study, will add new evidence that could support the use of CTR in cardiac patients clinical guidelines.

Effects of neuromuscular training compared to classic strength-resistance training in patients with acute coronary syndrome: A study protocol for a randomized controlled trial

The aim of the present clinical trial is to evaluate the effectiveness of neuromuscular versus classical strength-resistance training as part of a cardiac rehabilitation programme in patients following acute coronary syndrome. The study is designed as a double-blinded, randomised, and controlled clinical trial. Thirty participants suffering from acute coronary syndrome who meet our inclusion criteria will be recruited by a private tertiary hospital. The intervention group will follow 20 sessions of a cardiac rehabilitation programme divided into two parts: aerobic training and neuromuscular strength-resistance training. The control group will complete the same aerobic training as well as a classical strength-resistance training workout programme. The primary outcome of the study will be the mean difference in change from baseline in the Incremental Shuttle Walking Test. The secondary outcomes will be the cardiorespiratory fitness of the patients (assessed by means of the Chester Step Test), lower-limb performance (assessed with the 30-Second Chair Stand Test and Single-Leg Squat Test), lower-limb strength (hip flexor handheld dynamometry), sexual dysfunction assessment (Sex Health Inventory for Men) and quality of life (EQ-5D-5L). This work will provide evidence for the effectiveness of a neuromuscular versus a classic strength-training programme in terms of cardiorespiratory fitness, lower-limb performance capacities and quality of life, in cardiac patients. The data obtained could lead to more effective and functional workouts which, in turn, may enhance the speed at which these patients can return to their everyday activities of life and improve the efficiency of their movement patterns and heart responses. Furthermore, patients may find neuromuscular workout routines more motivating and engaging, thus encouraging them to adopt healthier lifestyle patterns.

Patient education interventions for health behaviour change in adults diagnosed with coronary heart disease: A protocol for a systematic review and meta-analysis

AIM

To assess the efficacy of structured patient education on disease-related knowledge and health behaviour change outcomes in adults with coronary heart disease.

DESIGN

Systematic review and meta-analyses including meta-regression on education duration.

METHODS

Seven databases (including Medline, Pubmed (non-Medline), CINAHL, PsycINFO, Embase, Emcare and Cochrane central register of controlled trials) will be searched from inception through 2020 to identify relevant randomized controlled trials testing interventions to improve health behaviours and disease-related knowledge in adults with coronary heart disease. Risk for bias will be assessed using the Cochrane Risk for Bias tool. Data will be synthesized using random-effects meta-analyses in Comprehensive Meta-Analysis Version 3. Heterogeneity will be assessed using Cochrane's Q statistic and the I-squared statistic will be reported. Meta-regression will be used to determine the effect of intervention duration. Publication bias will be assessed using funnel plots and Egger's test and which will be adjusted by conducting the trim-and-fill test when necessary. Funding for this project began in March 2020.

DISCUSSION

We will examine knowledge and behaviour outcomes including physical activity, dietary habits, smoking and medication adherence for patients with coronary heart diseases. This review will be the most comprehensive meta-analysis of structured patient education interventions to date and the first to analyse the effect of education duration.

IMPACT

The efficacy of patient education on knowledge and behaviour outcomes for patients with coronary heart diseases has not yet been established. This systematic review will determine the efficacy of structured patient education on knowledge and behaviour outcomes and determine whether the duration of patient education influences patient outcomes and thus guide intervention design. PROSPERO registration Number: CRD42020173467.

The impact of coronary heart disease prevention on work productivity: a 10-year analysis

AIMS

To determine the impact of preventing new (incident) cases of coronary heart disease (CHD) on years of life and productivity, using the novel measure 'productivity-adjusted life year' (PALY), over the next 10 years.

METHODS AND RESULTS

A dynamic life table model was constructed for the total Australian working-age population (15-69 years) over 10 years (2020-2029), separated by CHD status. Productivity estimates were sourced from the literature. The PALY was ascribed a financial value in terms of gross domestic product (GDP) per equivalent full-time worker. The total number of years lived, PALYs, and economic burden (in terms of GDP per PALY) were estimated. The model simulation was repeated assuming incidence was reduced, and the differences represented the impact of CHD prevention. All outcomes were discounted by 5% per annum. Over 10 years, the total projected years lived and PALYs in the Australian working-age population (with and without CHD) were 133 million and 83 million, respectively, amounting to A$17.2 trillion in GDP. We predicted more than 290 000 new (incident) CHD cases over the next 10 years. If all new cases of CHD could be prevented during this period, a total of 4 000 deaths could be averted, resulting in more than 8 000 years of life saved and 104 000 PALYs gained, equivalent to a gain of nearly A$21.8 billion (US$14.8 billion) in GDP.

CONCLUSION

Prevention of CHD will prolong years of life lived and productive life years, resulting in substantial economic benefit. Policy makers and employers are encouraged to engage in preventive measures addressing CHD.
