Modifiable risk factors and motivation for lifestyle change of CVD patients starting cardiac rehabilitation: The BENEFIT study

BACKGROUND

To improve lifestyle guidance within cardiac rehabilitation (CR), a comprehensive understanding of the motivation and lifestyle-supporting needs of patients with cardiovascular disease (CVD) is required.

OBJECTIVES

This study's purpose is to evaluate patients' lifestyle and their motivation, self-efficacy and social support for change when starting CR.

METHODS

1782 CVD patients (69 % male, mean age 62 years) from 7 Dutch outpatient CR centers participated between 2020 and 2022. Modifiable risk factors were assessed with a survey and interviews by healthcare professionals during CR intake.

RESULTS

Most patients exhibited an elevated risk in 3-4 domains. Elevated risks were most prominent in domains of (1) waist circumference and BMI (2) physical exercise (3) healthy foods intake and (4) sleep duration. Most patients chose to focus on increasing physical exercise, but about 20 % also wanted to focus on a healthy diet and/or decrease stress levels. Generally, motivation, self-efficacy and social support to reach new lifestyle goals were high. However, patients with an unfavorable risk profile had lower motivation and self-efficacy to work on lifestyle changes, while patients with lower social support had a higher chance to quit the program prematurely.

CONCLUSIONS

Our results underscore the need to begin CR with a comprehensive lifestyle assessment and highlight the importance of offering lifestyle interventions tailored to patients' specific modifiable risk factors and lifestyle-supporting needs, targeting multiple lifestyle domains. Expanding the current scope of CR programs to address diverse patient needs and strengthening support may enhance motivation and adherence and lead to significant long-term benefits for cardiovascular health.

Challenges and solutions to implementing cardiac rehabilitation in a low- and middle-income country

BACKGROUND

Cardiac rehabilitation (CR) remains greatly underutilized, especially in low- and middle-income countries (LMIC). It is therefore important to explore factors that contribute to this, as perceived by health-care professionals (HCPs).

RESEARCH DESIGN AND METHODS

This was a qualitative study using in-depth interviews that enrolled 18 HCPs (i.e. six each of physicians, physiotherapists, and nurses; mean experience in CR: 17.9 ± 11.8 yrs) working in cardiovascular care, and CR across private and government hospitals (both teaching and non-teaching) in India.

RESULTS

The main challenges were related to lack of referrals, perceived lack of benefit from CR, poor infrastructure within hospitals and health systems, and differences in practice. The perceived inadequacies were lack of competencies in CR, limited task sharing strategies, and ineffective utilization of existing human resources. Devising strategies to improve awareness and competencies, facilitating task sharing, and remodeling holistic care with an active CR component may be beneficial to facilitate greater implementation of CR in India.

CONCLUSIONS

Challenges, inadequacies, and solutions to implementing CR have been explored by involving various HCPs commonly involved in delivering CR across different health systems in a LMIC.

Mortality Benefits of Cardiac Rehabilitation in Coronary Artery Disease Are Mediated by Comprehensive Risk Factor Modification: A Retrospective Cohort Study

BACKGROUND

Cardiac rehabilitation (CR) is a multicomponent intervention to reduce adverse outcomes from coronary artery disease, but its mechanisms are not fully understood. The aims of this study were to examine the impact of CR on survival and cardiovascular risk factors, and to determine potential mediators between CR attendance and reduced mortality.

METHODS AND RESULTS

A retrospective mediation analysis was conducted among 11 196 patients referred to a 12-week CR program following an acute coronary syndrome event between 2009 and 2019. A panel of cardiovascular risk factors was assessed at a CR intake visit and repeated on CR completion. All-cause and cardiovascular mortality were ascertained via health care administrative data sets at mean 4.2-year follow-up (SD, 2.81 years). CR completion was associated with reduced all-cause (adjusted hazard ratio [HR], 0.67 [95% CI, 0.54-0.83]) and cardiovascular (adjusted HR, 0.57 [95% CI, 0.40-0.81]) mortality, as well as improved cardiorespiratory fitness, lipid profile, body composition, psychological distress, and smoking rates (P<0.001). CR attendance had an indirect effect on all-cause mortality via improved cardiorespiratory fitness (ab=-0.006 [95% CI, -0.008 to -0.003]) and via low-density lipoprotein cholesterol (ab=-0.002 [95% CI, -0.003 to -0.0003]) and had an indirect effect on cardiovascular mortality via cardiorespiratory fitness (ab=-0.007 [95% CI, -0.012 to -0.003]).

CONCLUSIONS

Cardiorespiratory fitness and lipid control partly explain the mortality benefits of CR and represent important secondary prevention targets.

Integrating Cardiac Rehabilitation in Stroke Recovery

Stroke remains a top contributor to long-term disability in the United States and substantially limits a person's physical activity. Decreased cardiovascular capacity is a major contributing factor to activity limitations and is a significant health concern. Addressing the cardiovascular capacity of stroke survivors as part of poststroke management results in significant improvements in their endurance, functional recovery, and medical outcomes such as all-cause rehospitalization and mortality. Incorporation of a structured approach similar to the cardiac rehabilitation program, including aerobic exercise and risk factor education, can lead to improved cardiovascular function, health benefits, and quality of life in stroke survivors.

Psychological interventions for depression and anxiety in patients with coronary heart disease, heart failure or atrial fibrillation

BACKGROUND

Depression and anxiety occur frequently (with reported prevalence rates of around 40%) in individuals with coronary heart disease (CHD), heart failure (HF) or atrial fibrillation (AF) and are associated with a poor prognosis, such as decreased health-related quality of life (HRQoL), and increased morbidity and mortality. Psychological interventions are developed and delivered by psychologists or specifically trained healthcare workers and commonly include cognitive behavioural therapies and mindfulness-based stress reduction. They have been shown to reduce depression and anxiety in the general population, though the exact mechanism of action is not well understood. Further, their effects on psychological and clinical outcomes in patients with CHD, HF or AF are unclear.

OBJECTIVES

To assess the effects of psychological interventions (alone, or with cardiac rehabilitation or pharmacotherapy, or both) in adults who have a diagnosis of CHD, HF or AF, compared to no psychological intervention, on psychological and clinical outcomes.

SEARCH METHODS

We searched the CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL databases from 2009 to July 2022. We also searched three clinical trials registers in September 2020, and checked the reference lists of included studies. No language restrictions were applied.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing psychological interventions with no psychological intervention for a minimum of six months follow-up in adults aged over 18 years with a clinical diagnosis of CHD, HF or AF, with or without depression or anxiety. Studies had to report on either depression or anxiety or both.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were depression and anxiety, and our secondary outcomes of interest were HRQoL mental and physical components, all-cause mortality and major adverse cardiovascular events (MACE). We used GRADE to assess the certainty of evidence for each outcome.

MAIN RESULTS

Twenty-one studies (2591 participants) met our inclusion criteria. Sixteen studies included people with CHD, five with HF and none with AF. Study sample sizes ranged from 29 to 430. Twenty and 17 studies reported the primary outcomes of depression and anxiety, respectively. Despite the high heterogeneity and variation, we decided to pool the studies using a random-effects model, recognising that the model does not eliminate heterogeneity and findings should be interpreted cautiously. We found that psychological interventions probably have a moderate effect on reducing depression (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -0.65 to -0.06; 20 studies, 2531 participants; moderate-certainty evidence) and anxiety (SMD -0.57, 95% CI -0.96 to -0.18; 17 studies, 2235 participants; moderate-certainty evidence), compared to no psychological intervention. Psychological interventions may have little to no effect on HRQoL physical component summary scores (PCS) (SMD 0.48, 95% CI -0.02 to 0.98; 12 studies, 1454 participants; low-certainty evidence), but may have a moderate effect on improving HRQoL mental component summary scores (MCS) (SMD 0.63, 95% CI 0.01 to 1.26; 12 studies, 1454 participants; low-certainty evidence), compared to no psychological intervention. Psychological interventions probably have little to no effect on all-cause mortality (risk ratio (RR) 0.81, 95% CI 0.39 to 1.69; 3 studies, 615 participants; moderate-certainty evidence) and may have little to no effect on MACE (RR 1.22, 95% CI 0.77 to 1.92; 4 studies, 450 participants; low-certainty evidence), compared to no psychological intervention.

AUTHORS' CONCLUSIONS

Current evidence suggests that psychological interventions for depression and anxiety probably result in a moderate reduction in depression and anxiety and may result in a moderate improvement in HRQoL MCS, compared to no intervention. However, they may have little to no effect on HRQoL PCS and MACE, and probably do not reduce mortality (all-cause) in adults who have a diagnosis of CHD or HF, compared with no psychological intervention. There was moderate to substantial heterogeneity identified across studies. Thus, evidence of treatment effects on these outcomes warrants careful interpretation. As there were no studies of psychological interventions for patients with AF included in our review, this is a gap that needs to be addressed in future studies, particularly in view of the rapid growth of research on management of AF. Studies investigating cost-effectiveness, return to work and cardiovascular morbidity (revascularisation) are also needed to better understand the benefits of psychological interventions in populations with heart disease.

Current Role and Future Perspectives of Cardiac Rehabilitation in Heart Disease

As a comprehensive secondary prevention program, cardiac rehabilitation (CR) is a beneficial and cost-effective intervention for patients with heart disease, but the participation rate of patients in CR is low globally. In recent years, due to the COVID-19 pandemic and scientific and technological advances, an increasing number of alternative CR modes have been developed, such as remote CR, home-based CR, hybrid CR and virtual CR. These alternative CR modes represent changes and new opportunities for patients with heart disease. In this review, we will discuss in detail the impact of CR on patients with different types of heart disease, review the various alternative CR models, and explore some prospects for the future of CR in the field of heart disease.

Impact of Cardiac Rehabilitation Health Insurance Coverage on Cardiac Rehabilitation Use in Korea Using an Interrupted Time Series

BACKGROUND

Since 2017, the cardiac rehabilitation (CR) program in Korea has been included in the coverage provided by the National Health Insurance to alleviate financial burden. Our study aimed to identify changes in the CR program use according to the implementation of CR coverage.

METHODS AND RESULTS

We obtained data from the electronic medical records of a tertiary hospital in Seoul, Korea from January 2014 to February 2020. Data from 2988 patients with acute coronary syndrome who underwent percutaneous coronary intervention were included. To examine the CR use trend among patients undergoing percutaneous coronary intervention, the electronic medical records data of the patients were aggregated quarterly, resulting in a maximum of 24 repeated measures for each patient. Segmented regression is often used to estimate the effects of interventions in an interrupted time series. Policy implementation led to a prompt increase in the probability of CR use (odds ratio [OR], 3.99 [95% CI, 2.89-5.51]). After the implementation of CR coverage, no significant change in CR use (OR, 0.97 [95% CI, 0.92-1.01]) was observed. After percutaneous coronary intervention, more patients opted for CR, especially those receiving education compared with exercise (education: OR, 87.44 [95% CI, 36.79-207.83] versus exercise: OR, 1.99 [95% CI, 1.43-2.76]).

CONCLUSIONS

The implementation of CR coverage resulted in a rapid increase in the probability of CR use. Use of the educational program was higher than that of the exercise program. Given the persistently low use of CR, it is imperative to stimulate its adoption by increasing its availability.

The Attitudes of Patients with Cardiovascular Diseases towards Online Exercise with the Mobile Monitoring of Their Health-Related Vital Signs

The health care cost of cardiovascular diseases (CVD) in the EU is estimated to be today over 282 billion euros. It is well documented today that exercise training is one of the main strategies for secondary disease prevention and the follow-up integration of these patients. This study aimed to examine patients' attitudes towards online exercise with mobile monitoring of their vital signs. More specifically, the research objectives were as follows: (a) to examine patients' attitudes and expectations of online exercise, (b) cluster patients in high- and low-attitude groups and examine their intention to participate in online exercise, and (c) to examine age and gender differences in terms of their intention to exercise online. The final goal of this project was to develop a real application that could be of use to patients and professionals. Data were collected from fifty patients in the city of Thessaloniki, Greece. The results revealed that most patients were positive about exercising online if the programs were perceived as fun and, especially, safe. The use of an online monitoring application with the distant supervision of health professionals could both motivate them and strengthen their feeling of safety.

Exercise-based cardiac rehabilitation after acute myocardial infarction in Sweden - standards, costs, and adherence to European guidelines (The Perfect-CR study)

AIMS

Information on standards including structure- and process-based metrics and how exercise-based cardiac rehabilitation (EBCR) is delivered in relation to guidelines is lacking. The aims of the study were to evaluate standards and adherence to guidelines at Swedish CR centers and to conduct a cost analysis of the physiotherapy-related activities of EBCR.

METHODS AND RESULTS

EBCR standards at all 78 CR centers in Sweden in 2016 were surveyed. The questions were based on guideline-recommended core components of EBCR for patients after a myocardial infarction (MI). The cost analysis included the identification, quantification, and valuation of EBCR-related cost items. Patients were offered a pre-discharge consultation with a physiotherapist at n = 61, 78% of the centers. A pre-exercise screening visit was routinely offered at n = 64, 82% of the centers, at which a test of aerobic capacity was offered in n = 58, 91% of cases, most often as a cycle ergometer exercise test n = 55, 86%. A post-exercise assessment was offered at n = 44, 56% of the centers, with a functional test performed at n = 30, 68%. Almost all the centers n = 76, 97% offered supervised EBCR programs. The total cost of delivering physiotherapy-related activities of EBCR according to guidelines was approximately 437 euro (4,371 SEK) per patient. Delivering EBCR to one MI patient required 11.25 hours of physiotherapy time.

CONCLUSION

While the overall quality of EBCR programs in Sweden is high, there are several areas of potential improvement to reach the recommended European standards across all centers. To improve the quality of EBCR, further compliance with guidelines is warranted.

Is cardiac rehabilitation after pci as effective as cabg? The first experience from the eastern mediterranean region cardiac rehabilitation registry

BACKGROUND

The effectiveness of cardiac rehabilitation (CR) programs following either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) has been separately studied. Few studies have compared the effects of similar CR programs between PCI and CABG. This study aimed to compare the effects of CR in patients recruited following either PCI or CABG on coronary heart disease risk factors, psychological variables, and functional capacity.

METHODS

For this retrospective study, the documents of the CR program registry of the Isfahan Cardiovascular Research Institute were reviewed from 2008 to 2021. Patients with ischemic heart disease undergoing PCI or CABG were enrolled in an 8-week exercise-based cardiac rehabilitation program. Demographics, smoking status, clinical data, echocardiographic parameters, laboratory data, functional capacity, and psychological status were assessed.

RESULTS

Patients who underwent CABG (n=557) were more likely to be referred to CR than those who underwent PCI (n=440). All variables changed significantly after the CR program compared to their baseline value in both the PCI and CABG groups. However, low-density lipoprotein and total cholesterol levels, peak systolic blood pressure, and resting and peak diastolic blood pressure did not change in any of the groups, and fasting blood sugar (p=0.01) and triglyceride (TG) (p=0.01) levels significantly decreased only in the PCI group. Between-group comparisons indicated that after adjustment, no significant difference was observed between the PCI and CABG groups except for TG, which was significantly reduced in the PCI group (p=0.01).

CONCLUSION

The CR program was equally effective in patients who underwent either PCI or CABG.

Physiotherapy-Led Health Promotion Strategies for People with or at Risk of Cardiovascular Diseases: A Scoping Review

Cardiovascular diseases (CVD) are prevalent and lead to high morbidity and mortality globally. Physiotherapists regularly interact with patients with or at risk of CVDs (pwCVDs). This study aimed to assess the nature of existing evidence, interventional approaches used, and the population groups included in physiotherapy-led health promotion (PLHP) for pwCVDs. The scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Medline, PubMed, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and PEDro databases were searched from inception until June 2023. Two reviewers independently screened the titles, abstracts, and full text and conducted data extraction. All conflicts were resolved with a third reviewer. A total of 4992 records were identified, of which 20 full-text articles were included in the review. The studies had varied populations, including those with stroke, coronary artery diseases, peripheral artery diseases, hypertension, diabetes, and multiple CVD risk factors. The interventions ranged from exercise and physical activity programmes, dietary interventions, education, and counselling sessions with various supplementary approaches. Most interventions were short-term, with less than 12 months of follow-up. Interventions were personalised and patient-centred to promote adherence and health behaviour change. Among the included studies, 60% employed experimental designs, with the remainder using quasi-experimental designs. Although a wide range of PLHP strategies have been used for pwCVDs, exercise and physical activity were employed in 85% of the included studies. Other components of health promotion, such as sleep, smoking, and alcohol abuse, should be investigated within PLHP.

Time-Restricted Eating: A Novel Dietary Strategy for Cardiac Rehabilitation

Cardiac rehabilitation (CR) is a multimodal program considered to be the standard of care for secondary prevention of cardiovascular disease (CVD). The primary goals of CR are managing CVD risk factors and improving quality of life. Exercise is the cornerstone, but nutrition education delivered by registered dietitians (RDs) is a core component of CR. Yet patient constraints to adherence to dietary change and limited availability of RDs represent major barriers to the success of completion of nutrition intervention during CR. Therefore, nutritional strategies that reduce CVD risk factors, barriers to adherence, and have capacity for broad dissemination are warranted within CR programs. In this review, we propose time-restricted eating (TRE) as a nutrition strategy to improve the outcomes of CR by drawing on parallels to CVD in other populations and describe the available preliminary data on the efficacy of TRE for CVD. TRE is a dietary strategy that involves alternating periods of fasting and consumption of calories each day. We outline the feasibility, safety, and beneficial cardiometabolic impact of TRE from TRE research in other populations. We also discuss the potential for synergistic benefits of exercise when combined with TRE. Although there is currently limited research on TRE within CR programs, we highlight CR as a unique clinical setting where TRE could play a role in secondary prevention of CVD. Overall, we outline the potential of TRE as a promising nutrition strategy to enhance the benefits of CR.

A Theory-Based, Technology-Assisted Intervention in a Hybrid Cardiac Rehabilitation Program for Patients with Coronary Heart Disease: A Feasibility Study

PURPOSE

To assess the feasibility of a technology-assisted intervention in a hybrid cardiac rehabilitation program among patients with coronary heart disease.

METHODS

This study was a two-arm parallel randomized controlled trial. Twenty-eight patients with coronary heart disease were randomly assigned to either the intervention group, receiving a 12-week technology-assisted intervention (n = 14), or the control group (n = 14), receiving usual care. Guided by the Health Belief Model, the intervention group received three center-based, supervised exercise training sessions, a fitness watch that served as a cue to action, six educational videos, and a weekly video call. The Self-efficacy for Exercise, exercise capacity, and Health Promoting Lifestyle Profile II were assessed at baseline and immediately post-intervention (12-weeks).

RESULTS

Among the 28 patients who participated in this study, 85.7% completed the program, with a relatively low attrition rate (14.3%). The number of exercise training sessions accomplished by the participants in the intervention group was 51.27 ± 19.41 out of 60 sessions (85.5%) compared to 36.46 ± 23.05 (60.8%) in the control group. No cardiac adverse events or hospitalizations were reported throughout the study. Participants in the intervention group showed greater improvement in health-promoting behaviors when compared with the control group at 12 weeks. Within-group effects demonstrated improvement in exercise self-efficacy and exercise capacity among participants in the intervention group. A participant satisfaction survey conducted immediately post-intervention revealed that participants were "very satisfied" (23.1%) and "satisfied" (76.9%) with the technology-assisted intervention.

CONCLUSIONS

The findings demonstrated that technology-assisted intervention in a hybrid cardiac rehabilitation program was feasible and suggested to be beneficial in improving exercise self-efficacy, exercise capacity, and health promoting behavior among patients with coronary heart disease. A full-scale study is needed to determine its effectiveness in the long term.

Global perspectives on heart disease rehabilitation and secondary prevention: a scientific statement from the Association of Cardiovascular Nursing and Allied Professions, European Association of Preventive Cardiology, and International Council of Cardiovascular Prevention and Rehabilitation

Cardiovascular disease is a leading cause of death, morbidity, disability, and reduced health-related quality of life, as well as economic burden worldwide, with some 80% of disease burden occurring in the low- and middle-income country (LMIC) settings. With increasing numbers of people living longer with symptomatic disease, the effectiveness and accessibility of secondary preventative and rehabilitative health services have never been more important. Whilst LMICs experience the highest prevalence and mortality rates, the global approach to secondary prevention and cardiac rehabilitation, which mitigates this burden, has traditionally been driven from clinical guidelines emanating from high-income settings. This state-of-the art review provides a contemporary global perspective on cardiac rehabilitation and secondary prevention, contrasting the challenges of and opportunities for high vs. lower income settings. Actionable solutions to overcome system, clinician, programme, and patient level barriers to cardiac rehabilitation access in LMICs are provided.

Cardiac MRI-based right-to-left ventricular blood pool T2 relaxation times ratio correlates with exercise capacity in patients with chronic heart failure

BACKGROUND

MRI T2 mapping has been proven to be sensitive to the level of blood oxygenation. We hypothesized that impaired exercise capacity in chronic heart failure is associated with a greater difference between right (RV) to left ventricular (LV) blood pool T2 relaxation times due to a higher level of peripheral blood desaturation, compared to patients with preserved exercise capacity and to healthy controls.

METHODS

Patients with chronic heart failure (n = 70) who had undergone both cardiac MRI (CMR) and a 6-min walk test (6MWT) were retrospectively identified. Propensity score matched healthy individuals (n = 35) served as control group. CMR analyses included cine acquisitions and T2 mapping to obtain blood pool T2 relaxation times of the RV and LV. Following common practice, age- and gender-adjusted nominal distances and respective percentiles were calculated for the 6MWT. The relationship between the RV/LV T2 blood pool ratio and the results from 6MWT were evaluated by Spearman's correlation coefficients and regression analyses. Inter-group differences were assessed by independent t-tests and univariate analysis of variance.

RESULTS

The RV/LV T2 ratio moderately correlated with the percentiles of nominal distances in the 6MWT (r = 0.66) while ejection fraction, end-diastolic and end-systolic volumes showed no correlation (r = 0.09, 0.07 and - 0.01, respectively). In addition, there were significant differences in the RV/LV T2 ratio between patients with and without significant post-exercise dyspnea (p = 0.001). Regression analyses showed that RV/LV T2 ratio was an independent predictor of the distance walked and the presence of post-exercise dyspnea (p < 0.001).

CONCLUSION

The proposed RV/LV T2 ratio, obtained by two simple measurements on a routinely acquired four-chamber T2 map, was superior to established parameters of cardiac function to predict exercise capacity and the presence of post-exercise dyspnea in patients with chronic heart failure.

Personalized smart voice-based electronic prescription for remote at-home feedback management in cardiovascular disease rehabilitation: a multi-center randomized controlled trial

Objective

To investigate the quality and efficacy of remote at-home rehabilitation for patients with cardiovascular disease (CVD) using personalized smart voice-based electronic prescription, and further explore the standardized health management mode of remote family cardiac rehabilitation. Trial design: A multicenter, randomized (1:1), non-blind, parallel controlled study.

Methods

A total of 171 patients with CVD who were admitted to 18 medical institutions in China from April 2021 to October 2022 were randomly divided into a treatment group (86 cases) and a control group (85 cases) in a non-blinded experiment, based on the sequence of enrollment. The control group received routine at-home rehabilitation training, and the treatment group received remote feedback-based at-home cardiac rehabilitation management based on routine at-home rehabilitation training. The primary outcome was the difference in VO2peak (mL/min/kg) after 12 weeks. A linear mixed model was developed with follow-up as the dependent variable. Age and baseline data were utilized as covariates, whereas hospital and patient characteristics were adjusted as random-effect variables. As the linear mixed model can accommodate missing data under the assumption of random missing data, there was no substitute missing value for quantitative data.

Results

A total of 171 participants, with 86 in the experimental group and 85 in the control group, were included in the main analysis. The analysis, which used linear mixing model, revealed significant differences in cardiopulmonary function indexes (VO2/kg peak, VO2peak, AT, METs, and maximum resistance) at different follow-up time (0, 4, and 12 weeks) in the experimental group (p < 0.05). In the control group, there was no significant difference in cardiopulmonary values at different follow-up time (0, 4, and 12 weeks; p > 0.05). VO2/kg peak (LS mean 1.49, 95%CI 0.09-2.89, p = 0.037) and other indicators of cardiopulmonary function (p < 0.05) were significantly different between the experimental group and the control group at week 12. The results were comparable in the complete case analysis.

Conclusion

The remote home cardiac rehabilitation management mode using personalized smart voice-based electronic prescription provides several benefits to patients, including improvements in muscle strength, endurance, cardiopulmonary function, and aerobic metabolism. It also helps reduce risk factors for cardiovascular disease and enhances patients' self-management abilities and treatment compliance.Clinical trial registration: http://www.chictr.org.cn, identifier ChiCTR2100044063.

Cost-effectiveness of home-based cardiac rehabilitation: a systematic review

OBJECTIVE

Centre-based cardiac rehabilitation (CR) is recognised as cost-effective for individuals following a cardiac event. However, home-based alternatives are becoming increasingly popular, especially since COVID-19, which necessitated alternative modes of care delivery. This review aimed to assess whether home-based CR interventions are cost-effective (vs centre-based CR).

METHODS

Using the MEDLINE, Embase and PsycINFO databases, literature searches were conducted in October 2021 to identify full economic evaluations (synthesising costs and effects). Studies were included if they focused on home-based elements of a CR programme or full home-based programmes. Data extraction and critical appraisal were completed using the NHS EED handbook, Consolidated Health Economic Evaluation Reporting Standards and Drummond checklists and were summarised narratively. The protocol was registered on the PROSPERO database (CRD42021286252).

RESULTS

Nine studies were included in the review. Interventions were heterogeneous in terms of delivery, components of care and duration. Most studies were economic evaluations within clinical trials (8/9). All studies reported quality-adjusted life years, with the EQ-5D as the most common measure of health status (6/9 studies). Most studies (7/9 studies) concluded that home-based CR (added to or replacing centre-based CR) was cost-effective compared with centre-based options.

CONCLUSIONS

Evidence suggests that home-based CR options are cost-effective. The limited size of the evidence base and heterogeneity in methods limits external validity. There were further limitations to the evidence base (eg, limited sample sizes) that increase uncertainty. Future research is needed to cover a greater range of home-based designs, including home-based options for psychological care, with greater sample sizes and the potential to acknowledge patient heterogeneity.

Feasibility of a Virtual Educational Programme for Behaviour Change in Cardiac Patients from a Low-Resource Setting

Patient education is an integral part of recovery from a critical cardiac life event and a core component of cardiac rehabilitation (CR) programmes. This study addressed the feasibility of a virtual educational programme for behaviour change in CR patients from a low-resource setting in Brazil. Cardiac patients from a CR programme closed due to the pandemic received a 12-week virtual educational intervention (WhatsApp messages and bi-weekly calls from healthcare providers). Acceptability, demand, implementation, practicality, and limited efficacy were tested. Overall, 34 patients and 8 healthcare providers agreed to participate. The intervention was considered practical and acceptable by the participants, who reported a satisfaction median of 9.0 (7.4-10.0)/10 (patients) and 9.8 (9.6-10.0)/10 (providers). The main difficulties in carrying out the intervention activities were related to technology, motivation to self-learning, and a lack of in-person orientation. All the patients reported that the information included in the intervention was aligned with their information needs. The intervention was associated with changes in exercise self-efficacy, sleep quality, depressive symptoms, and performance of high-intensity physical activity. In conclusion, the intervention was considered feasible to educate cardiac patients from a low-resource setting. It should be replicated and expanded to support patients that face barriers to onsite CR participation. Challenges related to technology and self-learning should be addressed.

Translation, Cross-Cultural Adaptation and Psychometric Validation of the Arabic Version of the Cardiac Rehabilitation Barriers Scale (CRBS-A) with Strategies to Mitigate Barriers

Cardiac rehabilitation (CR) utilization is low, particularly in Arabic-speaking countries. This study aimed to translate and psychometrically validate the CR Barriers Scale in Arabic (CRBS-A), as well as strategies to mitigate them. The CRBS was translated by two bilingual health professionals independently, followed by back-translation. Next, 19 healthcare providers, followed by 19 patients rated the face and content validity (CV) of the pre-final versions, providing input to improve cross-cultural applicability. Then, 207 patients from Saudi Arabia and Jordan completed the CRBS-A, and factor structure, internal consistency, construct, and criterion validity were assessed. Helpfulness of mitigation strategies was also assessed. For experts, item and scale CV indices were 0.8-1.0 and 0.9, respectively. For patients, item clarity and mitigation helpfulness scores were 4.5 ± 0.1 and 4.3 ± 0.1/5, respectively. Minor edits were made. For the test of structural validity, four factors were extracted: time conflicts/lack of perceived need and excuses; preference to self-manage; logistical problems; and health system issues and comorbidities. Total CRBS-A α was 0.90. Construct validity was supported by a trend for an association of total CRBS with financial insecurity regarding healthcare. Total CRBS-A scores were significantly lower in patients who were referred to CR (2.8 ± 0.6) vs. those who were not (3.6 ± 0.8), confirming criterion validity (p = 0.04). Mitigation strategies were considered very helpful (mean = 4.2 ± 0.8/5). The CRBS-A is reliable and valid. It can support identification of top barriers to CR participation at multiple levels, and then strategies for mitigating them can be implemented.

Functional outcome after cardiac rehabilitation and its association with survival in heart failure across the spectrum of ejection fraction

BACKGROUND

There is limited evidence regarding the effects of cardiac rehabilitation (CR) in patients with heart failure and preserved ejection fraction (HFpEF).

METHODS

We studied 1784 patients admitted to inpatient CR. The patients were grouped into HFpEF (EF≥0.50), HF with mildly reduced EF (HFmrEF; EF 41-49), and HF with reduced EF (HFrEF; EF≤0.40). A standardized 6-min walking test was performed at admission and discharge. Measures of functional outcome were: (1) absolute increase in 6-min walking distance (6MWD) from admission to discharge >50 m and (2) increase in 6MWD to ≥300 among the patients who walked <300 m at admission.

RESULTS

After adjustment, the patients with HFpEF or HFmrEF were as likely as those with HFrEF to achieve an increase in 6MWD >50 m (odds ratio 0.95 [95%CI 0.71-1.24; p=0.648] and 1.04 [95%CI 0.77-1.41; p=0.769], respectively) or an increase in 6MWD to ≥300 m (odds ratio 0.79 [95%CI 0.51-1.23; p=0.299] and 0.65 [95%CI 0.38-1.12; p=0.118], respectively). The adjusted hazard ratio of 5-year mortality for patients who achieved an increase in 6MWD >50 m was 0.60 (95%CI 0.51-0.71; p<0.001) and that for patients who achieved an increase in 6MWD at discharge to ≥300 m 0.61 (95%CI 0.48-0.79; p<0.001). In each EF group, both outcomes remained independently associated with improved survival.

CONCLUSIONS

Our data suggest that patients with HFpEF or HFmrEF are as likely as those with HFrEF to benefit from CR in terms of functional improvement. Functional improvement was independently associated with improved long-term survival, regardless of EF.

Barriers and facilitators to return to work following cardiovascular disease: a systematic review and meta-synthesis of qualitative research

OBJECTIVES

Return to work is a key rehabilitation goal, however, people recovering from cardiovascular disease (CVD) often struggle with returning to work. The aim of this study was to conduct a systematic review and meta-synthesis of the existing qualitative evidence on barriers and facilitators to return to work experienced by people with CVD.

METHODS

A systematic literature search was conducted in PubMed, Embase, Web of Science, PsycINFO, Scopus and CINAHL in August 2022. The reference lists of the included articles were searched. The Critical Appraisal Skills Programme was used for quality appraisal and a meta-synthesis was employed.

FINDINGS

This review includes 15 studies of overall high methodological quality. Barriers covered four themes: physical limitations, psychological and relational factors, the working context and support within health and social care systems. Facilitators were related to five themes: return to normality, enhancing well-being, financial concerns, the working context and support within health and social care systems.

CONCLUSION

Our findings highlight that return to work following CVD is a complex process influenced by individual factors, as well as work-related factors, factors in the health and social care systems and social security policies and regulations. To improve return to work, this review illustrates a need for individualised, multidisciplinary and coordinated vocational rehabilitation programmes that accommodate potential barriers to re-employment. Similarly, this review highlights how vocational rehabilitation programmes should ensure individualised information and support early in the rehabilitation process, as well as the importance of engaging relevant stakeholders, such as employers, in making individualised return-to-work plans.

Effectiveness and reporting of nutrition interventions in cardiac rehabilitation programmes: a systematic review

AIMS

Dietary modification is essential for the secondary prevention of cardiovascular disease. However, there are limited published evidence syntheses to guide practice in the cardiac rehabilitation (CR) setting. This systematic review's objective was to assess effectiveness and reporting of nutrition interventions to optimize dietary intake in adults attending CR.

METHODS AND RESULTS

Randomized controlled trials (RCTs) of nutrition interventions within CR were eligible for inclusion and had to have measured change in dietary intake. MEDLINE, Embase, Emcare, PsycINFO, CINAHL, Scopus, and The Cochrane Library were searched from 2000 to June 2020, limited to publications in English. Evidence from included RCTs was synthesized descriptively. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool. This review is registered on PROSPERO; CRD42020188723. Of 13 048 unique articles identified, 11 were eligible. Randomized controlled trials were conducted in 10 different countries, included 1542 participants, and evaluated 29 distinct dietary intake outcomes. Five studies reported statistically significant changes in diet across 13 outcomes. Most nutrition interventions were not reported in a manner that allowed replication in clinical practice or future research.

CONCLUSION

There is a gap in research testing high-quality nutrition interventions in CR settings. Findings should be interpreted in the light of limitations, given the overall body of evidence was heterogenous across outcomes and study quality; 6 of 11 studies were conducted more than 10 years old. Future research should investigate strategies to optimize and maintain nutrition improvements for patients attending CR.

Understanding Facilitators and Challenges to Care Transition in Cardiac Rehabilitation: Perspectives and Assumptions of Healthcare Professionals

Cardiac rehabilitation is an essential part of treatment for patients with cardiovascular disease. Cardiac rehabilitation is increasingly organized outside hospital in community healthcare services. However, this transition may be challenging. The aim of this study was to examine assumptions and perspectives among healthcare professionals on how facilitators and challenges influence the transition from hospital to community healthcare services for patients in cardiac rehabilitation. The study followed the Interpretive Description methodology and data consisted of participant observations and focus group interviews. The analysis showed that despite structured guidelines aimed to support the collaboration, improvements could be made. Facilitators and challenges could occur in the collaboration between the healthcare professionals, in the collaboration with the patient, or because of the new reality for patients when diagnosed with cardiovascular disease.

Availability and nature of cardiac rehabilitation by province in Iran: A 2018 update of ICCPR's global audit

Background

Cardiac rehabilitation (CR) is scantly available in Iran, although it is the cost-benefit strategy in cardiac patients, It has not been established how CR is delivered within Iran. This study aimed to determine: (a) availability, density and unmet need for CR, and (b) nature of CR services in Iran by province.

Materials and Methods

In this cross-sectional sub-study of the global CR audit, program availability was determined through cardiovascular networks. An online survey was then disseminated to these programs in June 2016-2017 which assessed capacity and characteristics; a paper-based survey was disseminated in 2018 to nonresponding and any new programs. CR density and need was computed based on annual incidence of acute myocardial infarction (AMI) in each province.

Results

Of the 31 provinces, 12 (38.7%) had CR services. There were 30 programs nationally, all in capital cities; of these, programs in 9 (75.0%) provinces, specifically 22 (73.3%) programs, participated. The national CR density is 1 spot per 7 incident AMI patients/year. Unmet need is greatest in Khuzestan, Tehran and west Azerbaijan, with 44,816 more spots needed/year. Most programs assessed cardiovascular risk factors, and offered comprehensive services, delivered by a multi-disciplinary team, comprised chiefly of nurses, dietitians and cardiologists. Median dose is 14 sessions/program in supervised programs. A third of programs offered home-based services.

Conclusion

Where programs do exist in IRAN, they are generally delivered in accordance with guidelines. Therefore, we must increase capacity in CR services in all provinces to improve secondary prevention services.

Effectiveness of cardiac rehabilitation programs in improving medication adherence in patients with cardiovascular disease: a systematic review protocol

OBJECTIVE

The objective of this review is to measure the effectiveness of cardiac rehabilitation programs versus standard care on medication adherence in patients with cardiovascular disease.

INTRODUCTION

Poor adherence to long-term medications increases the risk of morbidity and mortality, and decreases quality of life in patients with cardiovascular diseases. Several strategies have been trialed to improve medication adherence, one of which is cardiac rehabilitation programs. Although evidence has indicated that such programs increase medication adherence, the extent of their effectiveness and translation into clinical practice is not well documented. Our systematic review will collect and analyze the available evidence for clinical practice implementation.

INCLUSION CRITERIA

The search will aim to locate randomized controlled trials. Where randomized controlled trials are not available, quasi-experimental studies, case-control studies, observational studies, and other study designs will be included. Studies that measure effectiveness of cardiac rehabilitation programs compared with standard care on medication adherence in cardiovascular disease patients will be included.

METHODS

Databases, including MEDLINE (Ovid), Emcare (Ovid), Embase (Ovid), Cochrane CENTRAL, Scopus, CINAHL (EBSCO), and unpublished sources will be searched. Articles in English and non-English-language articles with an English abstract, published from database inception to the present, will be included. Articles will be screened and reviewed by 2 independent reviewers for inclusion. Critical appraisal tools will be applied to the included studies. Data will be extracted using the appropriate extraction tools and synthesized for the objectives of the study.

Women-Focused Cardiovascular Rehabilitation: An International Council of Cardiovascular Prevention and Rehabilitation Clinical Practice Guideline

Women-focused cardiovascular rehabilitation (CR; phase II) aims to better engage women, and might result in better quality of life than traditional programs. This first clinical practice guideline by the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) provides guidance on how to deliver women-focused programming. The writing panel comprised experts with diverse geographic representation, including multidisciplinary health care providers, a policy-maker, and patient partners. The guideline was developed in accordance with Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Reporting Items for practice Guidelines in HealTh care (RIGHT). Initial recommendations were on the basis of a meta-analysis. These were circulated to a Delphi panel (comprised of corresponding authors from review articles and of programs delivering women-focused CR identified through ICCPR's audit; N = 76), who were asked to rate each on a 7-point Likert scale in terms of impact and implementability (higher scores positive). A Web call was convened to achieve consensus; 15 panelists confirmed strength of revised recommendations (Grading of Recommendations Assessment, Development, and Evaluation [GRADE]). The draft underwent external review from CR societies internationally and was posted for public comment. The 14 drafted recommendations related to referral (systematic, encouragement), setting (model choice, privacy, staffing), and delivery (exercise mode, psychosocial, education, self-management empowerment). Nineteen (25.0%) survey responses were received. For all but 1 recommendation, ≥ 75% voted to include; implementability ratings were < 5/7 for 4 recommendations, but only 1 for effect. Ultimately 1 recommendation was excluded, 1 separated into 2 and all revised (2 substantively); 1 recommendation was added. Overall, certainty of evidence for the final recommendations was low to moderate, and strength mostly strong. These recommendations and associated tools can support all programs to feasibly offer some women-focused programming.

Identifying the Optimal Exercise Prescription for Patients with Coronary Artery Disease Undergoing Cardiac Rehabilitation: Protocol for a Systematic Review and Network Meta-Analysis of Randomized Control Trials

Coronary artery disease (CAD) is one of the leading causes of mortality and morbidity. Exercise-based cardiac rehabilitation (EBCR) has been shown to improve clinical outcomes in these patients, and yet clinicians are often challenged to prescribe the most effective type of exercise training. Therefore, this systematic review and network meta-analysis (NMA) aims to formally quantify the optimal dose of exercise training interventions to improve exercise capacity and quality of life by undertaking direct and indirect pooled comparisons of randomized controlled trials. A detailed search will be conducted on PubMed/MEDLINE, Cumulative Index to Nursing and Allied Health (CINAHL), EMBASE and Web of Science. Two reviewers will screen the existing literature and assess the quality of the studies. Disagreements will be resolved through consensus. We anticipate that the analysis will include pairwise and Bayesian network meta-analyses. Most of the trials have studied the impact of exercise training comparing one or two modalities. As a result, little evidence exists to support which interventions will be most effective. The current NMA will address this gap in the literature and assist clinicians and cardiac rehabilitation specialists in making an informed decision. Results will be disseminated through peer-reviewed journals. Ethical approval is not applicable, as no research participants will be involved. PROSPERO Registration number: CRD42022262644.

Improving cardiac rehabilitation patient adherence via personalized interventions

Objectives

Despite documented benefits and physicians’ recommendations to participate in cardiac rehabilitation (CR) programs, the average dropout rate remains between 12–56%. This study’s goal was to demonstrate that using personalized interventions can significantly increase patient adherence.

Method

Ninety-five patients (ages 18–90) eligible for the CR program were randomly recruited and received personalized interventions using the Well-Beat system. Adherence levels were compared to those of a historical control group. The Well-Beat system provided Sheba CR Health Care Provider (HCP) guidelines for personalized patient-therapist dialogue. The system also generated ongoing personalized text messages for each patient sent twice a week and related each patient’s dynamic profile to their daily behavior, creating continuity, and reinforcing the desired behavior.

Results

A significant increase in patient adherence to the CR program: Three months after initiation, 76% remained active compared to the historical average of 24% in the matched control group (log-rank p-value = 0.001).

Conclusions

Using an Artificial Intelligence (AI)-based engine that generated recommendations and messages made it possible to improve patient adherence without increasing HCP load, benefiting all. Presenting customized patient insights to the HCP and generating personalized communications along with action motivating text messages can also be useful for remote care.

Physical Activity Level and Perspectives of Participants Transitioning from Onsite to Virtual Cardiac Rehabilitation during the Early COVID-19 Pandemic: A Mixed-Method Study

This mixed-method study aimed to compare physical activity (PA) patterns of a cross-over cardiac rehabilitation (CR) cohort with a center-based CR cohort and to explore barriers and facilitators of participants transitioning and engaging in virtual CR. It included the retrospective self-reported PA of a cross-over CR cohort (n = 75) and a matched center-based CR cohort (n = 75). Some of the participants included in the cross-over cohort (n = 12) attended semi-structured focus group sessions and results were interpreted in the context of the PRECEDE-PROCEED model. Differences between groups were not observed (p > 0.05). The center-based CR cohort increased exercise frequency (p = 0.002), duration (p = 0.007), and MET/minutes (p = 0.007) over time. The cross-over cohort increased exercise duration (p = 0.04) with no significant change in any other parameters. Analysis from focus groups revealed six overarching themes classified under predisposing factors (knowledge), enabling factors (external support, COVID-19 restrictions, mental health, personal reasons/preferences), and reinforcing factors (recommendations). These findings suggest an improvement of the PA levels of center-based CR cohort participants pre-pandemic and mitigated improvement in those who transitioned to a virtual CR early in the pandemic. Improving patients’ exercise-related knowledge, provider endorsements, and the implementation of group videoconferencing sessions could help overcome barriers to participation in virtual CR.

Post pandemic research priorities: A consensus statement from the HL-PIVOT

We have been amid unhealthy living and related chronic disease pandemics for several decades. These longstanding crises have troublingly synergized with the coronavirus disease 2019 (COVID-19) pandemic. The need to establish research priorities in response to COVID-19 can be used to address broad health and wellbeing, social and economic impacts for the future is emerging. Accordingly, this paper sets out a series of research priorities that could inform interdisciplinary collaboration between clinical sciences, public health, business, technology, economics, healthcare providers, and the exercise science/sports medicine communities, among others. A five-step methodology was used to generate and evaluate the research priorities with a focus on broad health and well-being impacts. The methodology was deployed by an international and interdisciplinary team from the Healthy Living for Pandemic Event Protection (HL- PIVOT) network. This team were all engaged in responding to the Pandemic either on the 'front-line' and/or in leadership positions ensuring the currency and authenticity of the process. Eight research priorities were identified clustered into two groups: i) Societal & Environmental, and ii) Clinical. Our eight research priorities are presented with insight from previously published research priorities from other groups.

Clinical Status of Cardiac Rehabilitation Manners and Models

Cardiac rehabilitation, which combines cardiology and preventive medicine, is an important part of treatment for cardiovascular diseases. Systematically, cardiac rehabilitation, including simultaneously inhibiting endothelial injury and promoting endothelial repair, is beneficial for physical and mental recovery and reduces the risks of recurrence and death in patients with cardiovascular diseases. Cardiac rehabilitation has developed rapidly in the last 50 years. A preliminary system for cardiac rehabilitation has been developed in China. The present article mainly focuses on the progress of cardiac rehabilitation from the aspects of goals, measures, and modes of research in the current scenario.

Efficacy of Phase II Remote Home Rehabilitation in Patients with Acute Myocardial Infarction after Percutaneous Coronary Intervention

Objective

To assess the efficacy of home-based cardiac rehabilitation and traditional outpatient rehabilitation in stage II after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).

Methods

From September 2019 to March 2020, 80 AMI patients in Cangzhou Central Hospital were randomly assigned to one of the two groups: the control group or the observation group, 40 cases in each group. The control group received old-fashioned outpatient rehabilitation treatment, and the study group received long-distance family rehabilitation nursing intervention. The blood pressure, examination results, compliance, satisfaction evaluation, incidence of cardiac events, heart rate, quality of life score, and 6-minute walking test were compared between the two groups.

Results

There were no deaths in both groups. There were significant differences in heart failure, unstable angina pectoris, unplanned readmission rate, walking compliance, and 6-minute walking test at 6 months after discharge (P < 0.05). There were substantial variances in left ventricular discharge portion, low-density lipoprotein, medication compliance, satisfaction, and quality of life (P < 0.05); there was substantial inconsistency in the 6-minute walking test concerning the two groups afterwards discharge for 3 months (P < 0.05).

Conclusion

Home rehabilitation is a new home cardiac rehabilitation model with high efficiency, convenience, and whole process monitoring and barrier-free follow-up management. It can effectively improve the cardiac function, workout patience and worth of life expectancy of victims with AMI, improve their self-management awareness and rehabilitation compliance, reduce the risk of cardiac events, and have a positive impact on the prognosis and rehabilitation of patients with AMI.

Prognostic value of functional capacity after transitional rehabilitation in older patients hospitalized for heart failure

BACKGROUND

Poor functional status is highly prevalent among older patients hospitalized for HF and marks a downward inflection point in functional and prognostic trajectories. We assessed the prognostic value of 6-min walk test after transitional cardiac rehabilitation in older patients hospitalized for heart failure (HF).

METHODS

We studied 759 patients aged ≥60 years who had been transferred to six inpatient rehabilitation facilities (IRF) from acute care hospitals after a hospitalization for acute HF. The primary outcome was 3-year all-cause mortality. We used multivariable Cox analysis to determine the association between 6-min walk distance (6MWD) at discharge from the IRFs and the primary outcome, adjusting for established predictors of death. The optimal cutoff for 6MWD was considered as the one that maximized the chi-square statistic.

RESULTS

Mean age was 75 ± 8 years. 6MWD significantly increased from admission to discharge (145 to 210 m; p < 0.001). The optimal cutoff for 6MWD was 198 m. After full adjustment, the hazard ratio for each 50 m-increase in discharge 6MWD was 0.90 (0.87-0.94; p < 0.001) and that for discharge 6MWD dichotomized at the optimal cutoff 0.48 (0.38-0.60; p < 0.001). The incidence rate of death/100 person-years for the patients who walked >198 m was 13.0 (10.0-15.5) compared with 30.8 (26.9-35.4) for those who walked <198 m. A statistically significant interaction of discharge 6MWD with left ventricular ejection fraction (EF) on the risk of death was observed (p value for interaction 0.047).

CONCLUSIONS

A rehabilitation intervention provided in the critical hospital-to-home transition period to older patients hospitalized for HF resulted in improved functional capacity. Increasing levels of functional capacity following rehabilitation were closely associated with decreasing risk of death; this association was significantly stronger for the subgroup with preserved EF.

Perceived return-to-work pressure following cardiovascular disease is associated with age, sex, and diagnosis: a nationwide combined survey- and register-based cohort study

Background

Return to work is a key rehabilitation goal for people with cardiovascular disease (CVD) because employment matters to individuals and societies. However, people recovering from CVD often struggle with returning to work and maintaining employment. To identify people in need of vocational counselling, we examined the probability of feeling under pressure to return to work following CVD.

Methods

We conducted a combined survey- and register-based study in a randomly selected, population-based cohort of 10,000 people diagnosed with atrial fibrillation, heart failure, heart valve disease, or ischaemic heart disease in 2018. The questionnaire covered return-to-work items, and we reported the probabilities of feeling under pressure to return to work with 95% confidence intervals (CIs) in categories defined by sex, age, and CVD diagnosis.

Results

The survey response rate was 51.1%. In this study, we included 842 respondents (79.7% men) aged 32–85 years, who had returned to work following a sick leave. Overall, 249 (29.7%) had felt pressure to return to work. The probability of feeling under pressure to return to work ranged from 18.3% (95% CI: 13.1–24.6) among men aged > 55 years with atrial fibrillation to 51.7% (95% CI: 32.5–70.6) among women aged ≤ 55 years with atrial fibrillation. In addition, 66.0% of all respondents had not been offered vocational rehabilitation, and 48.6% of those who reported a need for vocational counselling had unmet needs. Survey responses also indicated that many respondents had returned to work before feeling mentally and physically ready.

Conclusion

A substantial proportion of people with cardiovascular disease feel under pressure to return to work, and this pressure is associated with age, sex, and diagnosis. The results show that vocational rehabilitation must be improved and emphasize the importance of ensuring that cardiac rehabilitation programmes include all core rehabilitation components.

Predictors of Rehabilitation Referral Among Cardiovascular Surgical Patients

Objective

Cardiovascular disease (CVD) continues to be the leading cause of mortality globally. Cardiac rehabilitation (CR) programs act by modifying the evolution of CVD and mortality; however, CR programs are under-used. The aim was to determine the profile of patients that received rehabilitation after cardiac surgery.

Patients and Methods

A retrospective observational study was conducted from January 2017 to December 2017 at a single center. The study sample was chosen among patients admitted to the Intensive Care Unit of the Hospital Gregorio Marañón/Gregorio Marañón General University Hospital. Socio-demographic and clinical variables were collected.

Results

In the present study, 336 patients underwent cardiac surgery of which 63.8% were men and 87.1% had ≥1 cardiovascular risk factors. Of the total cohort, 24.7% were operated for ischemic heart disease, 47.9% valvulopathy, 11% underwent combined surgery, 3.6% cardiac transplantation, 6.5% aneurysms, and 3.9% congenital disease. In-hospital respiratory rehabilitation was prescribed to all patients. Only 4.8% of the patients received motor rehabilitation and 13.8% were referred to CR. We found higher referral rates among patients with more cardiovascular risk factors, <65 years of age, and those undergoing coronary surgery and heart transplantation. Age, ischemic heart disease, and overweight were independent predictors of CR referral.

Conclusion

The benefit of CR programs after cardiac surgery is widely described; however, the referral rate to CR remains low. It is crucial to optimize referral protocols for these patients.

A Structured Review of Commercially Available Cardiac Rehabilitation mHealth Applications Using the Mobile Application Rating Scale

PURPOSE

This study systematically evaluated the quality and functionalities of patient-facing, commercially available mobile health (mHealth) apps for cardiac rehabilitation (CR).

METHODS

We performed our search in two of the most widely used commercial mobile app stores: Apple iTunes Appstore and Google Play Store (Android apps). Six search terms were used to query relevant CR apps: "cardiac rehabilitation," "heart disease and remote therapy," "heart failure exercise," "heart therapy and cardiac recovery," "cardiac recovery," and "heart therapy." App quality was evaluated using the Mobile Application Rating Scale (MARS). App functionality was evaluated using the IQVIA functionality scale, and app content was evaluated against the American Heart Association guidelines for CR. Apps meeting our inclusion criteria were downloaded and evaluated by two to three reviewers, and interclass correlations between reviewers were calculated.

RESULTS

We reviewed 3121 apps and nine apps met our inclusion criteria. On average, the apps scored a 3.0 on the MARS (5-point Likert scale) for overall quality. The two top-ranking mHealth apps for CR for all three quality, functionality, and consistency with evidence-based guidelines were My Cardiac Coach and Love My Heart for Women, both of which scored ≥4.0 for behavior change.

CONCLUSION

Overall, the quality and functionality of free apps for mobile CR was high, with two apps performing the best across all three quality categories. High-quality CR apps are available that can expand access to CR for patients with cardiovascular disease.

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.

Women Have Lower Mortality Than Men After Attending a Long-Term Medically Supervised Exercise Program

PURPOSE

Medically supervised exercise programs (MSEPs) are equally recommended for men and women with cardiovascular disease (CVD). Aware of the lower CVD mortality in women, we hypothesized that among patients attending a MSEP, women would also have better survival.

METHODS

Data from men and women, who were enrolled in a MSEP between 1994 and 2018, were retrospectively analyzed. Sessions included aerobic, resistance, flexibility and balance exercises, and cardiopulmonary exercise test was performed. Date and underlying cause of death were obtained. Kaplan-Meier methods and Cox proportional hazards regression were used for survival analysis.

RESULTS

A total of 2236 participants (66% men, age range 33-85 yr) attended a median of 52 (18, 172) exercise sessions, and 23% died during 11 (6, 16) yr of follow-up. In both sexes, CVD was the leading cause of death (39%). Overall, women had a more favorable clinical profile and a longer survival compared to men (HR = 0.71: 95% CI, 0.58-0.85; P < .01). When considering those with coronary artery disease and similar clinical profile, although women had a lower percentage of sex- and age-predicted maximal oxygen uptake at baseline than men (58 vs 78%; P < .01), after adjusting for age, women still had a better long-term survival (HR = 0.68: 95% CI, 0.49-0.93; P = .02).

CONCLUSION

Survival after attendance to a long-term MSEP was better among women, despite lower baseline cardiorespiratory fitness. Future studies should address whether men and women would similarly benefit when participating in an MSEP.

Examining Facilitators and Barriers to Cardiac Rehabilitation Adherence in a Low-Resource Setting in Latin America from Multiple Perspectives

Cardiac rehabilitation (CR) is under-used, particularly in low-resource settings. There are few studies of barriers and facilitators to CR adherence in these settings, particularly considering multiple perspectives. In this multiple-method study, a cross-sectional survey including the Cardiac Rehabilitation Barriers Scale (each item scored on a five-point Likert scale) was administered to patients treated between February and July, 2019, in three CR centers in Colombia. A random subsample of 50 participants was invited to a focus group, along with an accompanying relative. Physiotherapists from the programs were invited to an interview, with a similar interview guide. Audio-recordings were transcribed and analyzed using interpretive description. A total of 210 patients completed the survey, and 9 patients, together with 3 of their relatives and 3 physiotherapists, were interviewed. The greatest barriers identified were costs (mean = 2.8 ± 1.6), distance (2.6 ± 1.6) and transportation (2.5 ± 1.6); the logistical subscale was highest. Six themes were identified, pertaining to well-being, life roles, weather, financial factors, healthcare professionals and health system factors. The main facilitators were encouragement from physiotherapists, relatives and other patients. The development of hybrid programs where patients transition from supervised to unsupervised sessions when appropriate should be considered, if health insurers were to reimburse them. Programs should consider the implications regarding policies of family inclusion.

Yoga-Based Cardiac Rehabilitation: Current Perspectives from Randomized Controlled Trials in Coronary Artery Disease

Coronary artery disease carries a high morbidity and mortality worldwide, and exercise-based cardiac rehabilitation programmes play a large role in secondary prevention. Exercise-based rehabilitation programmes are expensive, and in certain subgroups uptake is poor. Yoga has been suggested to show improvements in cardiovascular health which would support its use in cardiac rehabilitation programmes. We carried out a review of current randomized controlled trials to determine if yoga-based cardiac rehabilitation leads to reduced cardiac risk factors, and improved physiological and psychological outcomes in patients with coronary artery disease compared to standard care. Six randomized controlled studies were identified after a medical database search, and meta-analysis was carried out for the different outcomes. Overall, the addition of yoga to standard care resulted in improved subjective feeling of cardiac health and quality of life. There was also a trend towards improvement in left ventricular systolic function. Improvement in cardiac risk factors, MACE and psychological health in this cohort has still to be proven, but was not inferior to standard or enhanced care, and the benefits became more pronounced at longer follow-up. Future studies with longer follow-up and larger patient numbers would aid in accurately assessing the long-term benefit of yoga-based rehabilitation.

A systematic review of provider-and system-level factors influencing the delivery of cardiac rehabilitation for heart failure

BACKGROUND

There is a longstanding research-to-practice gap in the delivery of cardiac rehabilitation for patients with heart failure. Despite adequate evidence confirming that comprehensive cardiac rehabilitation can improve quality of life and decrease morbidity and mortality in heart failure patients, only a fraction of eligible patients receives it. Many studies and reviews have identified patient-level barriers that might contribute to this disparity, yet little is known about provider- and system-level influences.

METHODS

A systematic review using narrative synthesis. The aims of the systematic review were to a) determine provider- and system-level barriers and enablers that affect the delivery of cardiac rehabilitation for heart failure and b) juxtapose identified barriers with possible solutions reported in the literature. A comprehensive search strategy was applied to the MEDLINE, Embase, PsycINFO, CINAHL Plus, EThoS and ProQuest databases. Articles were included if they were empirical, peer-reviewed, conducted in any setting, using any study design and describing factors influencing the delivery of cardiac rehabilitation for heart failure patients. Data were synthesised using inductive thematic analysis and a triangulation protocol to identify convergence/contradiction between different data sources.

RESULTS

Seven eligible studies were identified. Thematic analysis identified nine overarching categories of barriers and enablers which were classified into 24 and 26 themes respectively. The most prevalent categories were 'the organisation of healthcare system', 'the organisation of cardiac rehabilitation programmes', 'healthcare professional' factors and 'guidelines'. The most frequent themes included 'lack of resources: time, staff, facilities and equipment' and 'professional's knowledge, awareness and attitude'.

CONCLUSIONS

Our systematic review identified a wide range of provider- and system-level barriers impacting the delivery of cardiac rehabilitation for heart failure, along with a range of potential solutions. This information may be useful for healthcare professionals to deliver, plan or commission cardiac rehabilitation services, as well as future research.

Characteristics, outcomes and long-term survival of heart failure patients undergoing inpatient cardiac rehabilitation

OBJECTIVE

To investigate the association of CR participation with all-cause mortality after a hospitalization for HF and to describe the characteristics and functional and clinical outcomes of heart failure (HF) patients undergoing inpatient cardiac rehabilitation (CR).

DESIGN

Multicenter cohort study. The association between CR participation and all-cause mortality from discharge from the acute care setting was assessed using Cox regression analysis adjusting for established prognostic factors.

SETTING

Six inpatients rehabilitation facilities (IRF).

PARTICIPANTS

3,219 HF patients admitted to inpatient CR between January 2013 and December 2016. Of these patients, 1,455 had been transferred directly from acute care hospitals after a hospitalization for HF (CR-Group 1) and 1,764 had been admitted from the community due to worsening functional disability or worsening clinical conditions (CR-Group 2). Six hundred thirty-three patients not referred to CR after a hospitalization for HF served as control group (non-CR Group).

INTERVENTION

Cardiac rehabilitation.

MAIN OUTCOME MEASURE

long-term mortality. Secondary outcomes were: 1. Change in functional capacity, as assessed by change in 6-minute walking distance (6MWD) from admission to discharge; 2. Clinical outcomes of the index inpatient rehabilitation admission, including in-hospital mortality and unplanned (re)admission to the acute care.

RESULTS

Compared with the non-CR Group, the adjusted hazard ratios of mortality at 1, 3, and 5 years for CR-Group 1 patients were 0.82 (0.68-0.97), 0.81 (0.71-0.93), and 0.80 (0.70-0.91). 6MWD increased from 230 to 292 m (p<.001) and 43.4% of the patients gained >50 m improvement. Overall, 2.5% of the patients died in hospital and 4.7% of the patients experienced unplanned (re)admissions to acute care, with significant differences between Group 1 and Group 2.

CONCLUSIONS

Our data show that inpatient CR is effective in improving functional capacity and suggest that inpatient CR provided in the earliest period following a hospitalization for HF is associated with long-term improved survival.

Current Nutrition Practice in Cardiac Rehabilitation Programs

PURPOSE

This study sought to determine current practice regarding nutrition care within cardiac rehabilitation (CR) programs, including perceived barriers and facilitators to providing nutrition care in this setting.

METHODS

A cross-sectional survey was conducted in October and November 2019. Potential participants were program coordinators, identified through the Australian Cardiovascular Health and Rehabilitation Association program directory and invited to participate via e-mail.

RESULTS

Forty-nine respondents (response rate: 13%) are included in this analysis. Programs provided group (n = 42, 86%) and/or individual (n = 25, 51%) nutrition education, and most were supported by a dietitian (63%). However, the availability of dietitians and nutrition care provided at CR was variable. For example, individual education was consistently provided at 13 programs and usually by health professionals other than dietitians. Eight programs (16%) used a formal behavior change framework for nutrition care. Generally, respondents were positive about the role of nutrition; CR coordinators perceived nutrition as a valuable component of the program, and that they had good nutrition knowledge. An identified barrier was the financial resources available to support the provision of nutrition care.

CONCLUSIONS

To ensure that patients receive the benefits of evidence-based nutrition care, program staff may require additional support, particularly regarding the use of evidence-based behavior change techniques. Key facilitators that may be leveraged to achieve this include the high value and priority that CR program coordinators place on nutrition care.

Nutrition Intervention in Cardiac Rehabilitation: A REVIEW OF THE LITERATURE AND STRATEGIES FOR THE FUTURE

OBJECTIVE

Despite guideline consensus that quality of nutrition affects most modifiable cardiovascular disease risk factors, the implementation of dietary interventions varies considerably in cardiac rehabilitation (CR) programs. The purpose of this review is to highlight the current existing literature and provide recommendations on best practices for nutrition interventions and future research that support secondary prevention outcomes.

REVIEW METHODS

The review examines original investigations, systematic reviews, and guidelines regarding nutrition intervention in CR.

SUMMARY

Nutrition intervention in CR plays an integral role in the success of patients; however, the literature is limited and standardization of practice is in its infancy. The role of a qualified registered dietician nutritionist, standardization of dietary assessments, individualized and intensive nutrition interventions, and application of specific behavior change techniques are central components in improving diet in CR. This review provides an overview of the evidence-based cardioprotective diets, nutritional interventions and behavioral strategies in CR, and explores areas for best practices and opportunities for innovation in the delivery of nutrition intervention in CR.

Current Status of Cardiac Rehabilitation in the Regional Cardiocerebrovascular Centers in Korea

Regional Cardiocerebrovascular Centers (RCCs)—a Korean government initiative—seek to reduce medical gaps across regions, and their cardiac rehabilitation (CR) programs are expected to model post-acute care for the Korean CR program. Accordingly, this study aimed to evaluate the current status of CR programs in the RCCs. We distributed surveys on the CR condition, activity, and barriers to 12 RCCs in different provinces. The results revealed significant gaps in the annual number of acute myocardial infarction admissions, and CR candidates, capacity, and density across the 12 RCCs. The CR capacity (50–500) and density (0.42–7.36) indicated particularly large gaps. Twelve RCCs had the necessary facilities, equipment and personnel for CR assessments and management, with high CR referral (97%) and patient education (78%) rates. However, the inpatient CR exercise training (56%) participation rate was inadequate, with much lower enrollment (47%) and adherence (17%) rates to the outpatient CR program and large differences across centers. Therefore, this study’s results will provide the evidence required to establish special national health strategies to overcome the CR barriers of patient, doctor/hospital, and policy factors for activating Korean CR programs.
