Multimedia Exercise Training Program Improves Distance Walked, Heart Rate Recovery, and Self-efficacy in Cardiac Surgery Patients

The effect of web-based education on self-care behaviors in cardiovascular patients: application of the pender's health promotion model

BACKGROUND

Coronary artery disease is the most common cardiovascular disease, the mortality rate of which is increasing significantly. The most important way to prevent a second attack in patients undergoing angioplasty is self-care, which can be influenced by several factors such as the patient's beliefs. Thus, the present study aimed to determine the effect of a web-based intervention based on the Pender's health promotion model in patients with cardiovascular disease.

METHODS

The present clinical trial study was conducted with 99 patients undergoing angioplasty treatment referring to Bushehr Heart Specialist Center. Random sampling was done and the participants were divided into two groups (50 subjects in intervention group and 49 subjects in control group). The data collection tool was a three-part questionnaire (including demographic information, a researcher-made questionnaire based on the health promotion model constructs, and self-care behaviors), which was completed in three stages (before, two weeks, and three months after the intervention). In addition to routine hospital services, the intervention group received multimedia training based on the constructs of the Pender's health promotion model from the website. The control group received usual hospital services. Data were analyzed with chi-square, independent T-test and repeated measure ANOVA using SPSS-22 software.

RESULTS

The results showed that 2 weeks and 3 months after the intervention, the mean scores of perceived benefits, perceived self-efficacy and perceived social support had a significant increase in the intervention group compared to the control group, but the mean score of perceived barriers had a significant decrease in the intervention group (p < 0.001). Regarding self-care behaviors, after the intervention, the mean scores of self-care behaviors, physical activity, healthy diet, medication adherence and stress management had a significant increase in the intervention group compared to the control group (p < 0.001), but no significant was observed between the two groups in terms of changes in the non-smoking (p = 0.38).

CONCLUSION

The results of the study showed that the web-based educational intervention based on the health promotion model is useful in improving the self-care behaviors of cardiac patients undergoing angioplasty. Nursing education and care have a great role in improving the self-care behaviors of cardiovascular patients.

The efficacy of phase I cardiac rehabilitation training based on augmented reality on the self-efficacy of patients undergoing coronary artery bypass graft surgery: A randomized clinical trial

BACKGROUND

Open-heart surgery is considered one of the primary treatments for severe coronary artery stenosis, but it comes with its own set of complications. However, these complications can be reduced through the implementation of proper cardiac rehabilitation during phase I. This study aimed to examine the impact of phase I cardiac rehabilitation training, using augmented reality, on the self-efficacy of cardiac management in patients undergoing coronary artery bypass grafting.

METHODOLOGY

This randomized clinical trial study involved 60 patients who were admitted to the Cardiac Surgery Intensive Care Unit at Ghaem Hospital in Mashhad. The software used in this study consisted of various videos and educational images demonstrating physical exercises for cardiac rehabilitation. The software was developed to train the patients in the intervention group on the rehabilitation program, starting from their admission to the Intensive Care Unit until their discharge from the hospital. The collected data were analyzed using statistical tests such as independent t-test, Mann-Whitney test, paired t-test, chi-square test, as well as descriptive indicators. Cohen's d was also used to evaluate the magnitude of the effect size.

RESULTS

The findings of this study revealed that the total mean score for cardiovascular management self-efficacy significantly increased during the transfer to the Intensive Care Unit and at the time of discharge. Notably, the increase observed in the intervention group was significantly greater than that of the control group (P < 0.001).

CONCLUSION

The results of this study indicated that implementing early rehabilitation programs, using innovative educational technology like augmented reality, enhanced the self-efficacy of patients undergoing coronary artery bypass grafting. These findings suggest that such programs can be effectively employed as educational tools throughout different stages of cardiac rehabilitation.

Effect of Home-Based Cardiac Rehabilitation Program on Self-Efficacy of Patients With Implantable Cardioverter Defibrillator

Introduction

For more effective control and treatment of cardiac dysrhythmias caused by diseases, ischemia, or other causes, an implantable cardioverter defibrillator (ICD) is used. One of the effective ways for secondary prevention is the home-based cardiac rehabilitation (HBCR) which nurses have an effective role in its implementation.

Objective

The study aimed to investigate the effect of implementing HBCR programs on the self-efficacy of patients with ICD.

Methods

This is a semi-experimental study conducted on 70 patients who received ICD in Shahid Chamran Heart Center of Isfahan University of Medical Sciences (IUMS) in 2021. The patients were randomly assigned to intervention and control groups and were introduced to the practical concepts of HBCR during four training sessions. In the following, 3-month follow-up and trainings were continued by home visits, telephone follow-up, and use of social messaging networks due to the conditions of coronavirus disease 2019 (COVID-19) pandemic. The data were analyzed with SPSS/21.

Results

The findings showed that performing HBCR programs was effective in improving the self-efficacy of patients with ICDs. A significant trend in the implementation of the HBCR programs in two groups was shown using chi-square test and independent t-test and variance with repeated measurements (p < .001). There was no significant difference in self-efficacy score in both groups at the beginning of the study (p < .056).

Conclusion

Considering the effectiveness of HBCR programs on improving the self-efficacy of patients with ICDs, it can be used in the educational care programs of healthcare workers and in the strategic policies of health care services.

Heart Rate Variability-Guided Training for Improving Mortality Predictors in Patients with Coronary Artery Disease

The objective of this research was to investigate whether heart rate variability (HRV)-guided training improves mortality predictors to a greater extent than predefined training in coronary artery disease patients. Twenty-one patients were randomly allocated to the HRV-guided training group (HRV-G) or the predefined training group (PRED-G). They measured their HRV at home daily and trained three times a week for six weeks. Resting heart rate, isolated vagal-related HRV indices (i.e., RMSSD, HF, and SD₁), weekly averaged RMSSD, heart rate recovery, and maximum oxygen uptake were assessed before and after the training period. There was a statistically significant difference (p = 0.034) in the change in weekly averaged RMSSD in favor of the HRV-G, while no differences were found in the remaining analyzed variables (p > 0.050). Regardless of the training prescription method, exercise training decreased resting heart rate (p = 0.001; -4.10 [95% CI = -6.37--1.82] beats per minute (bpm)), and increased heart rate recovery at 2 min (p = 0.010; 4.33 [95% CI = 1.15-7.52] bpm) and maximum oxygen uptake (p < 0.001; 3.04 [95% CI = 1.70-4.37] mL·kg^-1·min^-1). HRV-guided training is superior to predefined training in improving vagal-related HRV when methodological factors are accounted for.

Effectiveness of early cardiac rehabilitation in patients with heart valve surgery: a randomized, controlled trial

OBJECTIVE

Complications of heart valve surgery lead to physical inactivity and produce harmful effects. This study aimed to investigate the role of a cardiac rehabilitation program and its long-term effect in patients after heart valve surgery.

METHODS

We performed a single-blind, randomized, controlled trial. Patients with heart valve surgery were randomly assigned to receive early cardiac rehabilitation (intervention group, 44 patients) or the usual care (control group, 43 patients). The intervention group performed sitting, standing, and walking exercises, followed by endurance training. The control group received usual care and did not engage in any physical activity. Physical function was assessed by the Short Physical Performance Battery (SPPB) and other measurement tools.

RESULTS

The intervention group showed a significant beneficial effect regarding physical capacity as shown by the SPPB and the 6-minute walking test at hospital discharge, and a better long-term effect was achieved at 6 months compared with the control group. An improvement in physical function (e.g., the SPPB) after hospital discharge predicted follow-up mortality (odds ratio = 0.416, 95% confidence interval: 0.218-0.792).

CONCLUSION

Early cardiac rehabilitation appears to be an effective approach to improve the physical function and survival of patients with heart valve surgery.

Educational approaches for patients with heart surgery: a systematic review of main features and effects

Introduction

Patients who undergo heart surgery are exposed to mental and physical difficulties after discharge from hospital. They often need support and follow-up after discharge. The use of educational approaches or solutions before or after heart surgery can increase patients' knowledge on the post-operative complications and self-care. The main purpose of this systematic review is to determine the applications of educational approaches and investigate the effects of these approaches on patients with heart surgery.

Method and materiel

A thorough search was conducted in Medline (through PubMed), Scopus, ISI web of science to select related articles published between 2011 and May 2022. All of the retrieved papers were screened according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.

Results

A total of 29 articles were obtained from the search, which included in this systematic review after being assessed based on inclusion and exclusion criteria. Most of the articles (n = 10, 34.48%) had been conducted in Canada and Iran, with the most significant number published in 2016. Out of 29 studies, 23 were experimental studies, and six were observational-analytical studies. The number of participants in the studies ranged from 11 to 600 (IQR1: 57.5, median: 88, IQR3: 190). In 28 (96.55%) studies, the educational approaches had a significant effect on clinical, economic or patient-reported outcomes. The greatest effect reported by the studies was related to clinical outcomes such as patient care improvement or change in clinical practice. The most effects in the patient-reported outcomes were related to improving patient satisfaction and patient knowledge. In terms of global rating scores, 17.24% of the included studies were considered as weak, 20.68% as moderate, and 62.06% as strong.

Conclusion

The results of systematic review showed that the use of educational approaches by patients before and after heart surgery can have significant effects on reducing stress and financial burden, and increasing the quality of care and level of knowledge in patients.

Influence of Nursing Intervention Based on Risk Assessment Model on Self-Efficacy and Postoperative Rehabilitation of Surgical Patients

The study aims to explore the effect of nursing intervention based on risk assessment model on self-efficacy and postoperative rehabilitation of surgical patients. The study applied a risk assessment model to the behavioral intervention of rehabilitation exercise in patients after percutaneous coronary intervention (PCI). A total of 157 patients were selected from a certain hospital, with 52 cases in the experimental group and 55 cases in the control group. A comprehensive cardiac rehabilitation intervention strategy based on TTM is given by researchers trained with professional knowledge, including dividing the stages of behavior change, developing a rehabilitation exercise plan through exercise teaching and exercise training, diet and lifestyle guidance, and urging patients to take regular medication and regular follow-up. The stage of rehabilitation movement behavior change improved. The preexperiment health status was (35.39 ± 14.31), and the overall health of the control group was (32.59 ± 15.41). Overall health status and QOL scores were relatively low in both the groups. The intervention group scored higher than the control group. After coronary stent implantation, the heart restores its original pumping function, various organs and tissues receive effective blood perfusion, and the symptoms of myocardial infarction such as profuse sweating, dizziness, fatigue, and precordial discomfort are effectively relieved. The physical discomfort can gradually improve or even recover to the functional state before the onset of the disease. Before the intervention, the self-efficacy score of the intervention group was (23.68 ± 4.49). After the intervention, the self-efficacy score of the intervention group was (26.21 ± 4.09), while the self-efficacy score of the control group before the intervention was (22.21 ± 4.1). After the intervention, the self-efficacy score of the control group was (25.23 ± 4.41). Although the self-efficacy score of the control group was improved, the difference was small, and the intervention effect was not obvious. It indicates that risk assessment intervention can improve patients' self-efficacy level and quality of life of postoperative rehabilitation patients.

The effects of a multimedia education on self-efficacy and self-esteem among patients with acute coronary syndrome: A clinical randomized trial

Background:

Acute Coronary Syndrome (ACS) is the first leading cause of death in the industrial world. It is associated with low self-esteem and self-efficacy. Given that patient education is a key role of nurses, this study sought to evaluate the effects of multimedia education on self-efficacy and self-esteem among patients with ACS.

Materials and Methods:

This randomized clinical trial was conducted in 2017 on 60 patients recruited from the two coronary care units of Hajar and Kashani hospitals, Shahrekord, Iran. Participants were randomly allocated to an intervention and a control group. The study intervention was a multimedia educational program. Data were collected before and 1 and 2 months after the intervention onset using a demographic questionnaire, the Cardiac Self-Efficacy Scale, and Coopersmith Self-Esteem Inventory. Data analyses were performed using repeated measures analysis of variance, t-test, Chi-square test, and Fisher's exact test.

Results:

The mean score of self-efficacy in the intervention group (F₂ = 119.26, p < 0.001) and in the control group (F₂ = 74.21, p < 0.001) significantly increased across the three measurement time points. The mean score of self-esteem in the intervention group significantly increased across the three measurement time points (F₂ = 101.19, p < 0.001), while it remained significantly unchanged in the control group (F₂ = 2.56, p = 0.086).

Conclusions:

Multimedia education is effective in significantly improving self-efficacy and self-esteem among patients with ACS. Therefore, nurses can use this strategy to improve these patients’ self-efficacy and self-esteem.

Efficacy of education delivery through multimedia and text messaging on the psychological parameters of patients scheduled for coronary angiography: a single-blind randomized controlled clinical trial

Background

Angiography is a highly effective invasive method for diagnosing coronary artery diseases but can lead to certain psychological problems such as stress, anxiety, and depression. This study aimed to compare the effects of education delivery through multimedia DVD content or text messaging in comparison with conventional printed pamphlets on the psychological parameters of patients scheduled for angiography.

Methods

This study was a randomized controlled clinical trial. We used the convenience sampling method to select 120 patients who met the inclusion criteria among individuals who were scheduled for elective coronary angiography. The patients were randomly divided into three groups through the block randomization method. The necessary educational tips for before, during, and after the angiography procedure were delivered to the patients in interventional group 1 (n = 40) and interventional group 2 (n = 40) through text messages and a multimedia DVD, respectively. The control group received routine hospital education through pamphlets besides the opportunity for verbal discussions with nurses. All educational content was delivered to the patients four days before the scheduled day of angiography. The DASS-21 questionnaire, consisting of the three domains of stress, anxiety, and depression, was used to collect the data. The questionnaire was administered at the time of delivering the educational content as the pretest evaluation and 30 min after the angiography procedure as the posttest evaluation. SPSS software, version 18, was used for statistical analysis.

Results

There was no significant difference among the three groups of patients in terms of pretest DASS-21 scores. Conversely, the mean posttest scores in all DASS-21 domains were significantly lower among the patients receiving education via the multimedia DVD or text messaging in comparison with the control group (P < 0.001). However, there were no statistically significant differences between the mean scores in all domains between the participants in the DVD and text messaging groups.

Conclusion

It seems that both DVDs and text messaging are more effective than conventional pamphlets in controlling the anxiety, stress, and stress of patients scheduled for elective coronary artery angiography.

Exercise-based cardiac rehabilitation and parasympathetic function in patients with coronary artery disease: a systematic review and meta-analysis

PURPOSE

The effects of exercise-based cardiac rehabilitation (CR) on parasympathetic modulation are controversial. This systematic review and meta-analysis aims to (a) determine the effect of exercise-based CR on heart-rate-derived indices associated with cardiac parasympathetic modulation in resting and post-exercise conditions in coronary artery disease (CAD) patients and (b) identify the possible moderator variables of the effect of exercise-based CR on parasympathetic modulation.

METHODS

We searched CENTRAL and Web of Science up to November 2018 for the following terms: adult CAD patients, controlled exercise-based CR interventions and parasympathetic modulation measured in resting (vagal-related heart rate variability [HRV] indices of the root mean square of the differences in successive in RR interval [RMSSD] and high frequency [HF]) and post-exercise (heart rate recovery [HRR]) pre- and post-intervention. We estimated a random-effects model of standardised mean difference (SMD) and mean difference (MD) for vagal-related HRV indices and HRR, respectively. We assessed the influence of categorical and continuous variables.

RESULTS

The overall effect size showed significant differences in RMSSD (SMD₊ = 0.30; 95% confidence interval [CI] = 0.12-0.49) and HRR (MD₊ = 5.35; 95% CI = 4.08-6.61 bpm) in favour of the exercise-based CR group. The overall effect size showed no differences in HF between groups (SMD₊ = 0.14; 95% CI,  -0.12-0.40). Heterogeneity analyses reached statistical significance, with high heterogeneity for HF (p < 0.001; I² = 70%) and HRR (p < 0.001; I² = 85%). Analysis of the moderator variables showed that the effect on HRR is greater in young patients (p = 0.008) and patients treated with percutaneous intervention (p = 0.020).

CONCLUSIONS

Exercise-based CR improves the post-exercise parasympathetic function, with greater effects in younger CAD patients and in those who were revascularised with percutaneous intervention. The effects on resting parasympathetic function are more controversial due to methodological inconsistencies in measuring HRV, with the use of RMSSD recommended instead of HF because its results show higher consistency. Future studies involving women, focusing on methodological issues, and performing other training methods are needed to increase our knowledge about this topic.

A longitudinal study on perceived health in cardiovascular patients: The role of conscientiousness, subjective wellbeing and cardiac self-efficacy

Cardiovascular disease (CVD) is the world’s most prevalent chronic disease and the leading chronic cause of morbidity. There are several psychosocial factors associated with quality of life during CVD. Our main objectives were to analyze the roles of conscientiousness, subjective wellbeing and self-efficacy beliefs. The sample comprised 514 patients (mean age 63.57 years) who were assessed twice over a nine-month interval. At Time 1, participants answered a questionnaire assessing conscientiousness, perceived subjective wellbeing (positive and negative affect, life satisfaction), cardiac self-efficacy and health-related quality of life (HRQoL). The same variables (except for conscientiousness) were re-assessed at Time 2. Results showed that conscientiousness had a positive relation with subjective wellbeing, cardiac self-efficacy, and HRQoL at Time 1. Moreover, cardiac self-efficacy at Time 1 had a positive longitudinal effect on HRQoL at Time 2, while controlling for autoregressive effects. Mediation analyses indicated that the relationship between conscientiousness and HRQoL was mediated by positive affect and cardiac self-efficacy. These results suggest the usefulness of psychosocial interventions aimed at promoting positive affect and self-efficacy beliefs among CVD patients.

Effect of electronic education based on health promotion model on physical activity in diabetic patients

BACKGROUND

By high prevalence of inactivity, particularly in diabetic patients, the need to effective interventions to promote physical activity is essential. The aim of this study was to determine the effects of education based on health promotion model (HPM) through multimedia on the physical activity in diabetic patients.

METHOD

In this quasi-experimental study, 76 patients with type II diabetes were evaluated (40 patents in intervention group and 36 patients in control group). The intervention group members and a friend or a family member, that could be supportive in physical activity, received teaching CD based on health promotion model. Both group members at the beginning of the study, two weeks and three months after the training, completed questionnaires. After data collection, statistical analysis was conducted using independent T-test, chi-square test, and repeated measurement of ANOVA.

RESULTS

Finding showed that self-efficacy (P<0.001), health status (p=0.032), benefits (P<0.001) and friends support in physical activity (P<0.001) were perceived to be higher, and barrier of physical activity (P<0.001) was perceived to be lower in multimedia group compared to control group 3 months after training. There was a significant difference in average of metabolic equivalent of task (MET) between two groups after the intervention (P<0.001).

CONCLUSION

Planning of education based on the HPM and implementation through multimedia can change belief about physical activity and increase participation in physical activity.
