Health-related quality of life and exercise-based cardiac rehabilitation in contemporary acute coronary syndrome patients: a systematic review and meta-analysis

Protocol for a feasibility randomized controlled trial of gentle yoga in older patients discharged from phase II cardiac rehabilitation

Background

Physical activity (PA) is essential following an acute cardiac event. Cardiac rehabilitation (CR) is commonly prescribed, and PA after CR is recommended. Because of age-related changes in functional ability and multi-comorbidity, many older cardiac patients struggle to continue performing PA at home after CR. Depressive symptoms and anxiety are prevalent in cardiac patients and associated with poor self-care, including lack of daily PA. Yoga has been demonstrated to improve psychological and physical health outcomes in cardiac patients, but it is unknown whether yoga, modified for older CR patients - Gentle Yoga - is beneficial in managing psychological distress and maintaining PA following phase II CR. Our specific aims are to:1) determine the feasibility and acceptability of a modified gentle yoga intervention delivered via video conferencing for older cardiac patients; 2) compare, at 3-month follow-up, the effects and determine effect sizes of a gentle yoga intervention versus control on psychological health and physical health.

Methods

We are conducting a 2-group (intervention versus control) randomized controlled pilot study. The intervention is a 12-week gentle yoga program delivered via video conference. Short-term effects will be evaluated at 3-month.

Conclusion

This study is designed to be suited for older cardiac patients who would not have access to supervised PA opportunities after facility-based CR to enhance PA. This study will provide data about the feasibility and acceptability of the protocol for older cardiac patients and will offer effect sizes to determine sample size for a fully powered randomized controlled trial.

Data-driven collaborative QUality improvement in Cardiac Rehabilitation (QUICR) to increase program completion: protocol for a cluster randomized controlled trial

BACKGROUND

Coronary heart disease (CHD) is the leading cause of deaths and disability worldwide. Cardiac rehabilitation (CR) effectively reduces the risk of future cardiac events and is strongly recommended in international clinical guidelines. However, CR program quality is highly variable with divergent data systems, which, when combined, potentially contribute to persistently low completion rates. The QUality Improvement in Cardiac Rehabilitation (QUICR) trial aims to determine whether a data-driven collaborative quality improvement intervention delivered at the program level over 12 months: (1) increases CR program completion in eligible patients with CHD (primary outcome), (2) reduces hospital admissions, emergency department presentations and deaths, and costs, (3) improves the proportion of patients receiving guideline-indicated CR according to national and international benchmarks, and (4) is feasible and sustainable for CR staff to implement routinely.

METHODS

QUICR is a multi-centre, type-2, hybrid effectiveness-implementation cluster-randomized controlled trial (cRCT) with 12-month follow-up. Eligible CR programs (n = 40) and the individual patient data within them (n ~ 2,000) recruited from two Australian states (New South Wales and Victoria) are randomized 1:1 to the intervention (collaborative quality improvement intervention that uses data to identify and manage gaps in care) or control (usual care with data collection only). This sample size is required to achieve 80% power to detect a difference in completion rate of 22%. Outcomes will be assessed using intention-to-treat principles. Mixed-effects linear and logistic regression models accounting for clusters within allocated groupings will be applied to analyse primary and secondary outcomes.

DISCUSSION

Addressing poor participation in CR by patients with CHD has been a longstanding challenge that needs innovative strategies to change the status-quo. This trial will harness the collaborative power of CR programs working simultaneously on common problem areas and using local data to drive performance. The use of data linkage for collection of outcomes offers an efficient way to evaluate this intervention and support the improvement of health service delivery.

ETHICS

Primary ethical approval was obtained from the Northern Sydney Local Health District Human Research Ethics Committee (2023/ETH01093), along with site-specific governance approvals.

Two-year prognosis and cardiovascular disease prevention after acute coronary syndrome; the role of cardiac rehabilitation: a French nationwide study

AIMS

To evaluate the impact of cardiac rehabilitation (CR) on optimization of secondary prevention treatments for acute coronary syndrome (ACS), medication persistence, medical follow-up, rehospitalisation, and all-cause mortality.

METHODS

The national health insurance database was used to identify all patients hospitalised for ACS in France in 2019 and those among them who received CR. Patients' characteristics and outcomes were described and compared between CR and non-CR patients. Poisson regression models were used to identify the impact of CR after adjusting for confounders. A Cox model was fitted to identify the variables related to mortality after adjustment for medication persistence and cardiologic follow-up.

RESULTS

In 2019, 22% of 134,846 patients hospitalised for ACS in France received CR within six months of their discharge. After one year, only 60% of patients who did not receive CR were still taking BASI drugs (combination of Beta blockers, Antiplatelets agents, Statins and RAAS Inhibitors). This rate and the medical follow-up rate were higher in patients who received CR. Two years after the ACS event, patients who received CR had better medical follow-up and lower mortality risk, after adjusting for cofounding variables (adjusted HR all-cause mortality = 0.65 [0.61-0.69]). After adjustment for the dispensing of cardiovascular drugs and cardiologic follow-up, the independent effect of CR was not as strong but remained significant (HR = 0.90 [95%CI: 0.84-0.95]).

CONCLUSION

Patients who received CR after hospitalisation for ACS had a better prognosis. Optimization of efficient secondary prevention strategies, improved medication persistence, and enhanced cardiologic follow-up seemed to play a major role.

Impact of Aerobic High-Intensity Interval Training Intervention and Mediterranean Diet Recommendations on Health-Related Quality of Life and Lifestyle Modification in Post-Myocardial Infarction Patients: Results From the INTERFARCT Surveys

This study aims to determine the impact of 2 (low vs high volume) high-intensity interval training (HIIT) programs with Mediterranean diet (MedDiet) recommendations on health-related quality of life (HRQoL) and lifestyle modification, and to examine the relationships between the changes in anxiety and depression with HRQoL and lifestyle variables after myocardial infarction (MI). Participants (n = 80) were randomized to attention control or one of the two supervised HIIT groups (2 d/weeks). Surveys before and after intervention (16 weeks): HRQoL (SF-36), anxiety and depression (HADS), MedDiet adherence (MEDAS), and physical activity (PA) and sedentary behavior (SB) levels. After intervention, there were improvements (P < .05) in HRQoL, HADS scores, and MedDiet adherence, with higher PA level in both HIIT groups with no between-HIIT group differences. The HADS score decline correlated (P < .05) with both the increase in physical component of SF-36 (r = .42), the overall metabolic expenditure (r = .26), and adherence to the MedDiet (r = .24), and the reduction in the SB (r = .35). HIIT exercise intervention with MedDiet recommendations improved HRQoL, along with reduced anxiety and depression symptoms, and a healthier lifestyle after MI. Better mental health was related to higher values of PA and MedDiet adherence.

Effect of an exercise-based cardiac rehabilitation program on quality of life of patients with chronic Chagas cardiomyopathy: results from the PEACH randomized clinical trial

To investigate the effect of an exercise-based cardiac rehabilitation program on the quality of life (QoL) of patients with chronic Chagas cardiomyopathy (CCC). PEACH study was a single-center, superiority randomized clinical trial of exercise training versus no exercise (control). The sample comprised Chagas disease patients with CCC, left ventricular ejection fraction < 45%, without or with HF symptoms (CCC stages B2 or C, respectively). QoL was assessed at baseline, after three months, and at the end of six months of follow-up using the SF-36 questionnaire. Patients randomized for the exercise group (n = 15) performed exercise training (aerobic, strength and stretching exercises) for 60 min, three times a week, during six months. Patients in the control group (n = 15) were not provided with a formal exercise prescription. Both groups received identical nutritional and pharmaceutical counseling during the study. Longitudinal analysis of the effects of exercise training on QoL, considering the interaction term (group × time) to estimate the rate of changes between groups in the outcomes (represented as beta coefficient), was performed using linear mixed models. Models were fitted adjusting for each respective baseline QoL value. There were significant improvements in physical functioning (β =  + 10.7; p = 0.02), role limitations due to physical problems (β =  + 25.0; p = 0.01), and social functioning (β =  + 19.2; p < 0.01) scales during the first three months in the exercise compared to the control group. No significant differences were observed between groups after six months. Exercise-based cardiac rehabilitation provided short-term improvements in the physical and mental aspects of QoL of patients with CCC.Trial registration: ClinicalTrials.gov Identifier: NCT02517632; August 7, 2015.

Temporal trends in admission for cardiac rehabilitation after an acute coronary syndrome in France from 2009 to 2021: Persistent sex, age and social disparities

BACKGROUND

Cardiac rehabilitation after an acute coronary syndrome is recommended to decrease patient morbidity and mortality and to improve quality of life.

AIMS

To describe time trends in the rates of patients undergoing cardiac rehabilitation after an acute coronary syndrome in France from 2009 to 2021, and to identify possible disparities.

METHODS

All patients hospitalized for acute coronary syndrome in France between January 2009 and June 2021 were identified from the national health insurance database. Cardiac rehabilitation attendance was identified within 6 months of acute coronary syndrome hospital discharge. Age-standardized cardiac rehabilitation rates were computed and stratified for sex and acute coronary syndrome subtypes (ST-segment elevation and non-ST-segment elevation). Patient characteristics and outcomes were described and compared. Factors independently associated with cardiac rehabilitation attendance were identified.

RESULTS

In 2019, among 134,846 patients with an acute coronary syndrome, 22.3% underwent cardiac rehabilitation within 6 months of acute coronary syndrome hospital discharge. The mean age of patients receiving cardiac rehabilitation was 62 years. The median delay between acute coronary syndrome hospitalization and cardiac rehabilitation was 32 days, with about 60% receiving outpatient cardiac rehabilitation. Factors significantly associated with higher cardiac rehabilitation rates were male sex, younger age (35-64 years), least socially disadvantaged group, ST-segment elevation, percutaneous coronary intervention and coronary artery bypass graft. Between 2009 and 2019, cardiac rehabilitation rates increased by 40% from 15.9% to 22.3%. Despite greater upward trends in women, their cardiac rehabilitation rate was significantly lower than that for men (14.8% vs. 25.8%). In 2020, cardiac rehabilitation attendance dropped because of the coronavirus disease 2019 pandemic.

CONCLUSIONS

Despite the health benefits of cardiac rehabilitation, current cardiac rehabilitation attendance after acute coronary syndrome remains insufficient in France, particularly among the elderly, women and socially disadvantaged people.

Uptake and implementation of cardiac telerehabilitation: A systematic review of provider and system barriers and enablers

BACKGROUND

Cardiac telerehabilitation has demonstrated effectiveness for patient health outcomes, but uptake and implementation into practice have been limited and variable. While patient-level influences on uptake have been identified, little is known about provider- and system-level factors.

AIMS

To identify provider and system barriers and enablers to uptake and implementation of cardiac telerehabilitation.

METHODS

A systematic review was conducted, including a search of six databases (MEDLINE, Embase, CINAHL, Scopus, Web of Science, and PsycINFO) from 2000 to March 2023. Two reviewers independently screened eligible articles. Study quality was evaluated according to study design by the Critical Appraisal Skills Programme (CASP) checklist for qualitative data, the Appraisal Tool for Cross-sectional Studies (AXIS), and the Mixed Methods Appraisal Tool (MMAT) for mixed methods. Data were analysed using narrative synthesis.

RESULTS

Twenty eligible studies (total 1674 participants) were included. Perceived provider-level barriers included that cardiac telerehabilitation is resource intensive, inferior to centre-based delivery, and lack of staff preparation. Whereas provider-level enablers were having access to resources, adequate staff preparation, positive staff beliefs regarding cardiac telerehabilitation and positive team dynamics. System-level barriers related to unaligned policy, healthcare system and insurance structures, technology issues, lack of plans for implementation, and inadequate resources. System-level enablers included cost-effectiveness, technology availability, reliability, and adaptability, and adequate program development, implementation planning and leadership support.

CONCLUSIONS

Barriers and enablers at both provider and system levels must be recognised and addressed at the local context to ensure better uptake of cardiac telerehabilitation programs.

Non-Immersive Virtual Reality-Based Therapy Applied in Cardiac Rehabilitation: A Systematic Review with Meta-Analysis

BACKGROUND

The aim of this systematic review with meta-analysis was to assess the effectiveness of non-immersive virtual reality (niVR) active videogames in patients who underwent cardiac rehabilitation (CR).

METHODS

A systematic review with meta-analysis, according to the PRISMA guidelines and previously registered in PROSPERO (CRD42023485240), was performed through a literature search in PubMed (Medline), SCOPUS, WOS, and PEDro since inception to 21 November 2023. We included randomized controlled trials (RCTs) that assessed the effectiveness of an niVR intervention, in comparison with conventional CR and usual care, on aerobic capacity and cardiovascular endurance (physical function), anxiety, depression, and quality of life (QoL). The risk of bias in individual studies was assessed using the Cochrane risk of bias tool. Effect size was estimated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI) in a random-effects model.

RESULTS

Nine RCT that met the inclusion criteria were included in the meta-analysis. The meta-analysis showed a moderate-to-large effect favoring niVR active videogames included in CR in increasing aerobic capacity and cardiovascular endurance (SMD = 0.74; 95% CI 0.11 to 1.37; p = 0.021) and reducing anxiety (SMD = -0.66; 95% CI -1.13 to -0.2; p = 0.006). Only 4.8% of patients reported adverse events while performing niVR active videogames.

CONCLUSIONS

Inclusion of niVR active videogames in CR programs is more effective than conventional CR in improving aerobic capacity and cardiovascular endurance and in reducing anxiety.

The Feasibility and Effects of Smartphone-Based Application on Cardiac Rehabilitation for Patients After Percutaneous Coronary Intervention: A Randomized Controlled Trial

BACKGROUND

Cardiac rehabilitation (CR) referral and participation are generally found to be underused worldwide. The data in Asian regions suggest significant underutilization compared with western countries.

OBJECTIVES

To promote the continuity and effects of CR, this study aimed at supporting self-care and improving CR effects in phase II CR with mobile health application for Macao patients who have undergone percutaneous coronary intervention.

METHODS

The study was a randomized controlled trial conducted between January 2018 and June 2020 in a nongovernmental Hospital. Social cognitive theory was applied in the intervention for an experimental group. Measurements including anxiety and depression level, medication adherence, exercise capacity, physical activity level, cardiovascular risk modification, self-efficacy, quality of life, use of healthcare resources, mHealth CR utility, and satisfaction were analyzed.

RESULTS

One hundred forty eligible patients were recruited, and 110 patients completed the study. Significant interventional effects of the experimental group were found on the reduction of total cholesterol, low-density lipoprotein, sitting time, anxiety level, and total anxiety and depression level ( P < .05). In addition, significant improvement on the 6-minute walk test, regular exercise performance, self-efficacy of cardiac exercise and diet, and quality of life were found as interventional effects in the experimental group ( P < .05). The feasibility of intervention was achieved in a satisfactory level.

CONCLUSIONS

This theoretically grounded mobile health CR study was a unique program tailor-made to meet the care needs of patients post percutaneous coronary intervention. It was feasible and effective to support CR effects and adherence and would inform further design of clinical practice and public policies.

Cardiac rehabilitation: pedagogical education strategies have positive effect on long-term patient-reported outcomes

This study examined whether patients attending cardiac rehabilitation (CR) based on the pedagogical strategy learning and coping (LC) led to improved health-related quality of life (HRQL), reduced symptoms of anxiety and depression and improved self-management 6 and 12 months after the completion of CR compared with patients attending CR based on the pedagogical strategy 'Empowerment, Motivation and Medical Adherence' (EMMA). A pragmatic cluster-controlled trial of two pedagogical strategies, LC and EMMA, including 10 primary health care settings and 555 patients diagnosed with ischaemic heart disease and referred to CR between August 2018 and July 2019 was conducted. In total, 312 patients replied to the questionnaires collected at baseline, 12 weeks, 6 months and 12 months after completing CR. Linear regression analyses adjusted for potential confounder variables and cluster effects were performed. We found clinically relevant and statistically significant improvements in HRQL, anxiety, depression and self-management after completing CR. The improvements were sustained at 6 and 12 months after the completion of CR. We found no differences between the two evidence-based patient education strategies. In conclusion, this study supports the use of evidence-based patient education strategies, but there is no evidence to suggest that one pedagogical strategy is superior to the other.

Socioeconomic Inequalities and Predictors of Cardiac Rehabilitation Referral: Real-World Evidence

OBJECTIVE

The aim of the study is to identify factors associated with cardiac rehabilitation referral after an acute coronary syndrome at a university hospital.

DESIGN

We analyzed 2814 hospitalizations due to acute coronary syndrome between 2017 and 2019 in Centro Hospitalar São João. The hospital's morbidity database was used to retrieve patient information. Cardiac rehabilitation referral and participation were identified from administrative databases and clinical records. Socioeconomic data were obtained from municipality of residence-level data rather than patient-specific data.

RESULTS

Of 2814 hospitalizations, 72% (2028 cases) were eligible for cardiac rehabilitation. Mean age was 65.2 ± 13.4 yrs; 72% men, 33% diabetic, 57.1% hypertensive, and 63.6% dyslipidemic. Cardiac rehabilitation referral rate was low, at 18.8%, with 42 (11.0%) not attending cardiac rehabilitation and 39 (10.2%) dropping out. Females (odds ratio = 0.72 [95% confidence interval = 0.52-1.00]), older patients (odds ratio = 0.57 [0.42-0.77]; 55-64 vs. <55 yrs), and those coming from lower-income municipalities (odds ratio = 0.53 [0.41-0.69], below median vs. above median) with lower education level (odds ratio = 0.70 [0.54-0.92]; ≤4 vs. >4 yrs) were less likely to be referred to cardiac rehabilitation.

CONCLUSIONS

There is a need for new strategies to promote cardiac rehabilitation in disadvantaged groups, as sex, age, and socioeconomic inequities in access to cardiac rehabilitation remain unresolved.

Predictors of gain in exercise capacity through cardiac rehabilitation: Sex and age matter

BACKGROUND

Cardiac rehabilitation (CR) is a cornerstone of secondary prevention that improves cardiovascular outcomes. However, the determinants of treatment success are poorly understood.

OBJECTIVES

We investigated the associations of health-related quality of life (HRQoL), sex, age, employment status and housing situation with improvement in exercise capacity throughout CR.

METHODS

We analyzed data from 392 CR outpatients (81% men and 19% women). Exercise capacity at baseline and upon completion of the program was measured with the 6-minute walk distance (6MWD). HRQoL at CR entry was assessed with the Short Form 36 Health Survey (SF-36).

RESULTS

A multivariable regression analysis revealed that both men and women showed significant improvement in exercise capacity (p < .001). Female sex (B = 18.118, 95% CI 0.341 - 36.035, p = .046) and younger age (B = -0.887, 95% CI -1.463 - -0.312, p = .003) emerged as predictors of greater improvement, while HRQoL, employment status, and housing situation were not associated with significant change in exercise capacity. The final model explained 25% of the variance in exercise capacity change (adjusted R2 = 0.25, p < .001).

CONCLUSIONS

Our results indicate that women and younger participants benefit from CR by improving their exercise capacity. Employment status, housing situation and HRQoL showed no effects on CR outcome.

Home-based versus centre-based cardiac rehabilitation

BACKGROUND

Cardiovascular disease is the most common cause of death globally. Traditionally, centre-based cardiac rehabilitation programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home-based and technology-supported cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation, especially during the SARS-CoV-2 pandemic. This is an update of a review previously published in 2009, 2015, and 2017.

OBJECTIVES

To compare the effect of home-based (which may include digital/telehealth interventions) and supervised centre-based cardiac rehabilitation on mortality and morbidity, exercise-capacity, health-related quality of life, and modifiable cardiac risk factors in patients with heart disease SEARCH METHODS: We updated searches from the previous Cochrane Review by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) on 16 September 2022. We also searched two clinical trials registers as well as previous systematic reviews and reference lists of included studies. No language restrictions were applied.

SELECTION CRITERIA

We included randomised controlled trials that compared centre-based cardiac rehabilitation (e.g. hospital, sports/community centre) with home-based programmes (± digital/telehealth platforms) in adults with myocardial infarction, angina, heart failure, or who had undergone revascularisation.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references for inclusion based on predefined inclusion criteria. Disagreements were resolved through discussion or by involving a third review author. Two authors independently extracted outcome data and study characteristics and assessed risk of bias. Certainty of evidence was assessed using GRADE.

MAIN RESULTS

We included three new trials in this update, bringing a total of 24 trials that have randomised a total of 3046 participants undergoing cardiac rehabilitation. A further nine studies were identified and are awaiting classification. Manual searching of trial registers until 16 September 2022 revealed a further 14 clinical trial registrations - these are ongoing. Participants had a history of acute myocardial infarction, revascularisation, or heart failure. Although there was little evidence of high risk of bias, a number of studies provided insufficient detail to enable assessment of potential risk of bias; in particular, details of generation and concealment of random allocation sequencing and blinding of outcome assessment were poorly reported. No evidence of a difference was seen between home- and centre-based cardiac rehabilitation in our primary outcomes up to 12 months of follow-up: total mortality (risk ratio [RR] = 1.19, 95% confidence interval [CI] 0.65 to 2.16; participants = 1647; studies = 12/comparisons = 14; low-certainty evidence) or exercise capacity (standardised mean difference (SMD) = -0.10, 95% CI -0.24 to 0.04; participants = 2343; studies = 24/comparisons = 28; low-certainty evidence). The majority of evidence (N=71 / 77 comparisons of either total or domain scores) showed no significant difference in health-related quality of life up to 24 months follow-up between home- and centre-based cardiac rehabilitation. Trials were generally of short duration, with only three studies reporting outcomes beyond 12 months (exercise capacity: SMD 0.11, 95% CI -0.01 to 0.23; participants = 1074; studies = 3; moderate-certainty evidence). There was a similar level of trial completion (RR 1.03, 95% CI 0.99 to 1.08; participants = 2638; studies = 22/comparisons = 26; low-certainty evidence) between home-based and centre-based participants. The cost per patient of centre- and home-based programmes was similar.

AUTHORS' CONCLUSIONS

This update supports previous conclusions that home- (± digital/telehealth platforms) and centre-based forms of cardiac rehabilitation formally supported by healthcare staff seem to be similarly effective in improving clinical and health-related quality of life outcomes in patients after myocardial infarction, or revascularisation, or with heart failure. This finding supports the continued expansion of healthcare professional supervised home-based cardiac rehabilitation programmes (± digital/telehealth platforms), especially important in the context of the ongoing global SARS-CoV-2 pandemic that has much limited patients in face-to-face access of hospital and community health services. Where settings are able to provide both supervised centre- and home-based programmes, consideration of the preference of the individual patient would seem appropriate. Although not included in the scope of this review, there is an increasing evidence base supporting the use of hybrid models that combine elements of both centre-based and home-based cardiac rehabilitation delivery. Further data are needed to determine: (1) whether the short-term effects of home/digital-telehealth and centre-based cardiac rehabilitation models of delivery can be confirmed in the longer term; (2) the relative clinical effectiveness and safety of home-based programmes for other heart patients, e.g. post-valve surgery and atrial fibrillation.

Physical Activity in Long COVID: A Comparative Study of Exercise Rehabilitation Benefits in Patients with Long COVID, Coronary Artery Disease and Fibromyalgia

Exercise in long COVID is poorly studied. Nevertheless, exerciserehabilitation could improve cardiorespiratory, muscular and autonomic functions. We aimed to investigate improvement in physical and autonomic performances of long COVID patients (n = 38) after a 4-week exercise rehabilitation program (3 sessions/week) compared to two control groups composed of coronary artery disease (n = 38) and fibromyalgia patients (n = 38), two populations for whom exercise benefits are well known. Efficacy of exercise training was assessed by a cardiopulmonary exercise test, a handgrip force test, and a supine heart rate variability recording at rest before and after the rehabilitation program. Cardiorespiratory and muscular parameters were enhanced after exercise rehabilitation in the three groups (p < 0.001). No significant difference was observed for the autonomic variables. Through this comparative study with control groups, we confirm and reinforce the interest of caring for long COVID patients without post-exertional symptom exacerbation by exercise rehabilitation of both strength and endurance training, by personalizing the program to the patient and symptoms.

A Prospective Cross-Sectional Study of Acute Coronary Syndrome Patients' Quality of Life and Drug Prescription Patterns at Riyadh Region Hospitals, Saudi Arabia

Acute coronary syndrome (ACS) is a leading cause of cardiovascular-related morbidity and mortality worldwide. The present study investigated the health-related quality of life (HRQOL) and drug prescribing patterns in ACS patients at Riyadh hospitals in Saudi Arabia. This study was a 12-month prospective cross-sectional study that included 356 patients with ACS. The current study showed that younger male (67.42%) and urban (75.84%) patients suffered more from ACS. Moreover, most patients with NSTEMI (51.69%) experienced Grade 1 dyspnea (33.43%) and NYHA Stage 2 (29.80%); however, STEMI patients were at greater mortality risk. The HRQOL questionnaire showed that ACS patients were significantly impaired in all QOL domains (emotional [23.0%, p = 0.001], physical [24.4%, p = 0.003], and social [27.2%, p = 0.002]). Furthermore, the most commonly prescribed medications were statins (93%), antiplatelets (84%), anticoagulants (79%), coronary vasodilators (65%), and beta-blockers (63%). Additionally, 64% of patients received PCIs or CABGs, with the majority of cases receiving PCIs (49%), whereas 9% received dual anticoagulant therapy. Thus, there is an urgent need to educate healthcare teams about the relevance of QOL in ACS control and prevention and the new ACS management recommendations. ACS is also growing among younger people, requiring greater attention and prevention.

Health-related factors of the Iraqi adult population during the 2020 COVID-19 pandemic: physical activity, eating behavior, quality of life, general health, and mood states cross-talk

BACKGROUND

The lockdown and social distancing caused by Coronavirus disease 2019 (COVID-19) may have changed Physical Activity Level (PAL), eating behavior, and health habits due to long-term confinement worldwide.

OBJECTIVE

This study aimed to evaluate the PAL, eating behavior, Quality of Life (QoL), General Health (GH), and mood states during COVID-19 confinement in a large sample of Iraqi adults.

METHODS

3738 healthy adults (age 18-70 years) residing in Halabjeh, Iraq answered the online questionnaires including the short form of international physical activity, GH, three-factor eating (TFEQ-R18), and a short form of the profile of mood states (POMS-SF) questionnaires. Data analysis was done by Chi-square, and Spearman's correlation using SPSS statistical software at a significant level of (P < 0.05).

RESULTS

The results showed unfavorable PAL, eating behavior, QoL, GH, and mood states in the total population. Low PAL was observed in 69.96% of the men and 75.99% of the women; only 3.60% of the men and 0.77% of the women had a high PAL. There was a significantly positive relationship between low PAL and the incidence of COVID-19 both in men and women (P = 0.801; r = 0.001; and P = 0.682; r = 0.011), respectively; While a significant negative relationship was observed between the moderate and high PAL and the incidence of COVID-19 in men (P = 0.011; r=-0.682 and P = 0.027, r=-0.589), and women (P = 0.001; r=-0.796 and P = 0.018, r=-0.623). No significant relationships were observed between PAL and eating behavior (men: P = 0.086; r = 0.256 and women: P = 0.365, r=-0.121); While, the results show significant positive relationships between PAL with QoL in men (P = 0.012; r = 0.623) and women (P = = 0.001; r = 0.837). based on the results, significant negative relationships between PAL with GH and mood state scores were observed in both men (P = 0.001; r=-0.837 and P = 0.001, r=-0.786) and women (P = 0.010; r=-0.652 and P = 0.001, r=-0.745), respectively.

CONCLUSIONS

The Iraqi adult population showed low PAL, GH, QoL, and mood state during COVID-19 which might be due to the confinement. Also, the significant relationships between low PAL with GH, and mood state recommends physical activity as a valuable health optimizing factor during the COVID-19 pandemic.

Hospital-Level Variation in Cardiac Rehabilitation After Myocardial Infarction in Japan During Fiscal Years 2014-2015 Using the National Database

Background: Cardiac rehabilitation (CR) is an evidence-based medical service for patients with acute myocardial infarction (AMI); however, its implementation is inadequate. We investigated the provision status and equality of CR by hospitals in Japan using a comprehensive nationwide claims database. Methods and Results: We analyzed data from the National Database of Health Insurance Claims and Specific Health Checkups in Japan for the period April 2014-March 2016. We identified patients aged ≥20 years with postintervention AMI. We calculated hospital-level proportions of inpatient and outpatient CR participation. The equality of hospital-level proportions of inpatient and outpatient CR participation was evaluated using the Gini coefficient. We included 35,298 patients from 813 hospitals for the analysis of inpatients and 33,328 patients from 799 hospitals for the analysis of outpatients. The median hospital-level proportions of inpatient and outpatient CR participation were 73.3% and 1.8%, respectively. The distribution of inpatient CR participation was bimodal; the Gini coefficients of inpatient and outpatient CR participation were 0.37 and 0.73, respectively. Although there were statistically significant differences in the hospital-level proportion of CR participation for several hospital factors, CR certification status for reimbursement was the only visually evident factor affecting the distribution of CR participation. Conclusions: The distributions of inpatient and outpatient CR participation by hospitals were suboptimal. Further research is warranted to determine future strategies.

An evidence map of systematic reviews on models of outpatient care for patients with chronic heart diseases

BACKGROUND

Chronic heart disease affects millions of people worldwide and the prevalence is increasing. By now, there is an extensive literature on outpatient care of people with chronic heart disease. We aimed to systematically identify and map models of outpatient care for people with chronic heart disease in terms of the interventions included and the outcomes measured and reported to determine areas in need of further research.

METHODS

We created an evidence map of published systematic reviews. PubMed, Cochrane Library (Wiley), Web of Science, and Scopus were searched to identify all relevant articles from January 2000 to June 2021 published in English or German language. From each included systematic review, we abstracted search dates, number and type of included studies, objectives, populations, interventions, and outcomes. Models of care were categorised into six approaches: cardiac rehabilitation, chronic disease management, home-based care, outpatient clinic, telemedicine, and transitional care. Intervention categories were developed inductively. Outcomes were mapped onto the taxonomy developed by the COMET initiative.

RESULTS

The systematic literature search identified 8043 potentially relevant publications on models of outpatient care for patients with chronic heart diseases. Finally, 47 systematic reviews met the inclusion criteria, covering 1206 primary studies (including double counting). We identified six different models of care and described which interventions were used and what outcomes were included to measure their effectiveness. Education-related and telemedicine interventions were described in more than 50% of the models of outpatient care. The most frequently used outcome domains were death and life impact.

CONCLUSION

Evidence on outpatient care for people with chronic heart diseases is broad. However, comparability is limited due to differences in interventions and outcome measures. Outpatient care for people with coronary heart disease and atrial fibrillation is a less well-studied area compared to heart failure. Our evidence mapping demonstrates the need for a core outcome set and further studies to examine the effects of models of outpatient care or different interventions with adjusted outcome parameters.

Exercise Self-efficacy Improvements During Cardiac Rehabilitation: IMPACT OF SOCIAL DISPARITIES

PURPOSE

The objective of this study was to determine exercise self-efficacy improvements during cardiac rehabilitation (CR) and identify predictors of exercise self-efficacy change in CR participants.

METHODS

Patients with coronary heart disease at four metropolitan CR sites completed the Exercise Self-efficacy Scale at entry and completion. A general linear model identified independent predictors of change in exercise self-efficacy.

RESULTS

The mean age of patients (n = 194) was 65.9 ± 10.5 yr, and 81% were males. The majority (80%) were married or partnered, 76% were White, and 24% were from an ethnic minority background. Patients received CR in-person (n = 91, 47%) or remote-delivered (n = 103, 54%). Exercise self-efficacy mean scores improved significantly from 25.2 ± 5.8 at CR entry to 26.2 ± 6.3 points at completion ( P = .025). The majority of patients (59%) improved their self-efficacy scores, 34% worsened, and 7% had no change. Predictors of reduced exercise self-efficacy change were being from an ethnic minority (B =-2.96), not having a spouse/partner (B =-2.42), attending in-person CR (B =1.75), and having higher exercise self-efficacy at entry (B =-0.37) (adjusted R2 = 0.247).

CONCLUSIONS

Confidence for self-directed exercise improves in most, but not all, patients during CR. Those at risk for poor improvement (ethnic minorities, single patients) may need extra or tailored support, and screening for exercise self-efficacy at CR entry and completion is recommended. Differences identified from CR delivery mode need exploration using robust methods to account for complex factors.

Effectiveness of a behavioral medicine intervention in physical therapy on secondary psychological outcomes and health-related quality of life in exercise-based cardiac rehabilitation: a randomized, controlled trial

BACKGROUND

Interventions promoting adherence to exercise-based cardiac rehabilitation (exCR) are important to achieve positive physical and psychological outcomes, but knowledge of the added value of behavioral medicine interventions for these measures is limited. The aim of the study was to investigate the added value of a behavioral medicine intervention in physical therapy (BMIP) in routine exCR on psychological outcomes and health-related quality of life (HRQoL) versus routine exCR alone (RC).

METHODS

A total of 170 patients with coronary artery disease (136 men), mean age 62.3 ± 7.9 years, were randomized at a Swedish university hospital to a BMIP plus routine exCR or to RC for four months. The outcome assessments included HRQoL (SF-36, EQ-5D), anxiety and depression (HADS), patient enablement and self-efficacy and was performed at baseline, four and 12 months. Between-group differences were tested with an independent samples t-test and, for comparisons within groups, a paired t-test was used. An intention-to-treat and a per-protocol analysis were performed.

RESULTS

No significant differences in outcomes between the groups were shown between baseline and four months or between four and 12 months. Both groups improved in most SF-36 domains, EQ-VAS and HADS anxiety at the four-month follow-up and sufficient enablement remained at the 12-months follow-up.

CONCLUSION

A BMIP added to routine exCR care had no significant effect on psychological outcomes and HRQoL compared with RC, but significant improvements in several measures were shown in both groups at the four-month follow-up. Since recruited participants showed a better psychological profile than the general coronary artery disease population, further studies on BMIP in exCR, tailored to meet individual needs in broader patient groups, are needed. Trial registration number NCT02895451, 09/09/2016, retrospectively registered.

Cardiac Rehabilitation for Patients With Stable Ischemic Heart Disease Without Revascularization - Rationale and Design of a Single-Arm Pilot Study

Background: Clinical practice guidelines strongly recommend optimal medical therapy (OMT), including lifestyle modification, pharmacotherapy, and exercise-based cardiac rehabilitation (CR), in patients with stable ischemic heart disease (SIHD). However, the efficacy and safety of CR in patients with SIHD without revascularization remain unclear. Methods and Results: The Prospective Registry of STable Angina RehabiliTation (Pre-START) study is a multicenter, prospective, single-arm, open-label pilot study to evaluate the efficacy and safety of CR on health-related quality of life (HRQL), exercise capacity, and clinical outcomes in Japanese patients with SIHD without revascularization. In this study, all patients will undergo guideline-based OMT and are encouraged to have 36 outpatient CR sessions within 5 months after enrollment. The primary endpoint is the change in the Seattle Angina Questionnaire-7 summary score between baseline and the 6-month visit; an improvement of ≥5 points will be defined as a clinically important change. Secondary endpoints include changes in other HRQL scores and exercise capacity between baseline and the 6-month visit, as well as clinical outcomes between enrollment and the 6-month visit. Conclusions: The Pre-START study will provide valuable evidence to elucidate the efficacy and safety of CR in patients with SIHD and indispensable information for a subsequent randomized controlled trial. The study was registered with the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (ID: UMIN000045415) on April 1, 2022.

Impact of Early COVID-19 Waves on Cardiac Rehabilitation Delivery in Australia: A National Survey

BACKGROUND

The novel coronavirus disease of 2019 (COVID-19) pandemic significantly disrupted health care, especially outpatient services such as cardiac rehabilitation (CR). We investigated the impact of early COVID-19 waves on the delivery of Australian CR programs, comparing this time period with usual practice prior to the pandemic (2019) and current practice (2021) once the early waves had subsided. Specifically, we aimed to understand how the delivery of programs during COVID-19 compared to usual practice.

METHODS

An anonymous online cross-sectional survey of Australian CR program staff was conducted, comprising three sections: program and respondent characteristics, COVID-19 impact on program delivery, and barriers to, and enablers of, program delivery. Respondents were asked to consider three key timepoints: 1) Pre-COVID-19 (i.e. usual practice in 2019), 2) Early COVID-19 waves (March-December 2020), and 3) Currently, at time of survey completion post early COVID-19 waves (May-July 2021).

RESULTS

Of the 314 Australian CR programs, 115 responses were received, of which 105 had complete data, representing a 33% response rate. All states and territories were represented. During early COVID-19 waves programs had periods of closure (40%) or reduced delivery (70%). The majority of programs reported decreased CR referrals (51.5%) and decreased participation (77.5%). The two core components of CR-exercise and education-were significantly impacted during early COVID-19 waves, affecting both the number and duration of sessions provided. Exercise session duration did not return to pre-pandemic levels (53.5 min compared to 57.7 min, p=0.02). The majority of respondents (77%) reported their CR program was inferior in quality to pre-pandemic and more organisational support was required across information technology, staffing, administration and staff emotional and social support.

CONCLUSION

Australian CR programs underwent significant change during the early COVID-19 waves, consistent with international CR reports. Fewer patients were referred and attended CR and those who did attend received a lower dose of exercise and education. It will be important to continue to monitor the long-term impacts of the COVID-19 pandemic to ensure CR programs return to pre-pandemic functioning and continue to deliver services in line with best practice and evidence-based recommendations.

Top 50 cited articles on cardiac rehabilitation: A bibliometric and altmetric analysis study

Background/Aim: Cardiovascular disease (CVD) is the leading cause of death globally, with an estimated 18.6 million deaths each year. Cardiac rehabilitation (CR) has positive effects on reducing the mortality and morbidity of CVD, so there is a growing interest in this field. The aim of this study was to analyze the top 50 cited articles in the field of CR. Methods: The Web of Science (WoS) database was searched for articles published between 1986 and 2021. A record was made of the following information for the bibliometric analysis: article title, year of publication, number of authors and their names, number of citations, citation index, journal of publication, impact factor, type of article, and source of funding. The altmetric attention score (AAS) was recorded using automatic software calculation. Results: The majority of articles were published in the journal “Circulation” (n=14) and the “Journal of the American College of Cardiology” (n=8). The country with the highest number of articles was the US (n=27), and the most cited author was P.A. Ades. Studies evaluating exercise-based rehabilitation, key components of CR, and secondary prevention were among the top cited articles. In terms of AAS, in addition to the titles mentioned, mobile health services that rely on communication technologies have also received attention. Conclusion: This study provides useful information for researchers interested in CR, including trends, topics of interest in the field, and potential research collaborations. It is intended to guide future, more comprehensive, and in-depth studies on CR.

The Impact of the SARS-CoV-2 Virus (COVID-19) Pandemic and the Rapid Adoption of Telehealth for Cardiac Rehabilitation and Secondary Prevention Programs in Rural and Remote Australia: A Multi-Method Study

INTRODUCTION

Centre-based cardiac rehabilitation (CR) programs were disrupted and urged to adopt telehealth modes of delivery during the COVID-19 public health emergency. Previously established telehealth services may have faced increased demand. This study aimed to investigate a) the impact of the COVID-19 pandemic on CR attendance/completion, b) clinical outcomes of patients with cardiovascular (CV) diseases referred to CR and, c) how regional and rural centre-based services converted to a telehealth delivery during this time.

METHODS

A cohort of patients living in regional and rural Australia, referred to an established telehealth-based or centre-based CR services during COVID-19 first wave, were prospectively followed-up, for ≥90 days (February to June 2020). Cardiac rehabilitation attendance/completion and a composite of CV re-admissions and deaths were compared to a historical control group referred in the same period in 2019. The impact of mode of delivery (established telehealth service versus centre-based CR) was analysed through a competitive risk model. The adaption of centre-based CR services to telehealth was assessed via a cross-sectional survey.

RESULTS

1,954 patients (1,032 referred during COVID-19 and 922 pre-COVID-19) were followed-up for 161 (interquartile range 123-202) days. Mean age was 68 (standard deviation 13) years and 68% were male. Referrals to the established telehealth program did not differ during (24%) and pre-COVID-19 (23%). Although all 10 centre-based services surveyed adopted telehealth, attendance (46.6% vs 59.9%; p<0.001) and completion (42.4% vs 75.4%; p<0.001) was significantly lower during COVID-19. Referral during vs pre-COVID-19 (sub hazard ratio [SHR] 0.77; 95% CI 0.68-0.87), and to a centre-based program compared to the established telehealth service (SHR 0.66; 95% CI 0.58-0.76) decreased the likelihood of CR uptake.

DISCUSSION

An established telehealth service and rapid adoption of telehealth by centre-based programs enabled access to CR in regional and rural Australia during COVID-19. However, further development of the newly implemented telehealth models is needed to promote CR attendance and completion.

Women's Health-Related Quality of Life Substantially Improves With Tailored Cardiac Rehabilitation: A SYSTEMATIC REVIEW AND META-ANALYSIS

PURPOSE

Exercise-based cardiac rehabilitation (EBCR) offers an opportunity to improve women's otherwise poorer outcomes from coronary heart disease compared with men. However, synthesized evidence for the benefits of EBCR for health-related quality of life (HRQL) is lacking for women. The current study addresses this gap.

METHODS

Four electronic databases (PubMed, CINAHL, SCOPUS, and Cochrane) were searched for studies reporting HRQL using validated questionnaires in women attending EBCR. Two reviewers independently screened articles and extracted data. A random effects model was used for meta-analysis, where possible.

RESULTS

Eleven studies (1237 women) were included, with seven suitable for meta-analyses. Participation in EBCR improved multiple domains of HRQL, with greatest improvements in Role Physical (mean differences [MD] = 19.09: 95% CI, 2.37-35.81), Physical Functioning (MD = 10.43: 95% CI, 2.60-18.27), and Vitality (MD = 9.59: 95% CI, 0.31-18.86) domains of the 12-Item Short Form Health Survey and the 36-Item Short Form Health Survey. Adding psychosocial components tailored for women to traditional EBCR produced further gains in HRQL in Bodily Pain (MD = 9.82: 95% CI, 4.43-15.21), Role Physical (MD = 8.48: 95% CI, 1.31-9.97), Vitality (MD = 8.17: 95% CI, 3.79-12.55), General Health (MD = 5.64: 95% CI, 1.31-9.97), and Physical Functioning (MD = 5.61: 95% CI, 0.83-10.40) domains.

CONCLUSIONS

Women attending EBCR achieve clinically meaningful improvements in multiple areas of HRQL, with added benefits when strategies were tailored to their needs. These benefits should be highlighted to promote EBCR uptake in women.

Mental and psychosocial health and health related quality of life before and after cardiac rehabilitation: a prospective cohort study with comparison to specific population norms

Background

Data on mental health improvement after cardiac rehabilitation (CR) are contradictory. The aim was to examine the mental and psycho-social health of patients admitted to our rehabilitation center following hospital treatment for acute coronary syndrome, before and after multidisciplinary CR.

Methods

Outcome was measured at admission and discharge by the 36-Item Short Form Survey (SF-36), the Symptom Checklist-90 Revised (SCL-90R), the Coping Strategy Questionnaire (CSQ) and the 6-min-walking distance test. The patients’ health status was compared with norms of sex-, age- and comorbidity-matched data from the German general population. Score differences from norms were measured by standardized mean differences (SMDs); health changes were quantified by standardized effect sizes (ESs). Their importance for comprehensive assessment was quantified by explorative factor analysis.

Results

Of n = 70 patients followed-up (male: 79%; mean age: 66.6 years), 79% had ≥ 3 comorbidities. At baseline, SF-36 Physical functioning (SMD = − 0.75), Role physical (− 0.90), Social functioning (SMD = − 0.44), and Role emotional (SMD = − 0.45) were significantly worse than the norm. After CR, almost all scores significantly improved by ES = 0.23 (SCL-90R Interpersonal sensitivity) to 1.04 (SF-36 Physical functioning). The strongest factor (up to 41.1% explained variance) for health state and change was the mental health domain, followed by function & pain (up to 26.3%).

Conclusions

Normative deficits in physical and psycho-social health were reported at baseline. After CR, at follow-up, all scores, except phobia, showed significant improvement. The comprehensive measurement of bio-psycho-social health should not be limited to depression and anxiety but include, especially, the somatization and social participation dimensions.

Effects of Exergaming in Patients with Cardiovascular Disease Compared to Conventional Cardiac Rehabilitation: A Systematic Review and Meta-Analysis

Background: Exercise-based cardiac rehabilitation (CR) programs are used for improving prognosis and quality of life in patients with cardiovascular disease (CVD). Nonetheless, adherence to these programs is low, and exercise-based CR programs based on virtual reality (i.e., exergaming) have been proposed as an alternative to conventional CR programs. However, whether exergaming programs are superior to conventional CR programs in patients with CVD is not known. Objective: This systematic review with meta-analysis was conducted to explore whether exergaming enhances exercise capacity, quality of life, mental health, motivation, and exercise adherence to a greater extent than conventional CR programs in patients with CVD. Method: Electronic searches were carried out in PubMed, Embase, Web of Science, and Cumulative Index to Nursing and Allied Health Literature databases up to June 2021. Meta-analyses were performed using robust variance estimation with small-sample corrections. The effect sizes were calculated as the mean differences (MD) or standardized mean differences (SMD) as appropriate. The SMD magnitude was classified as trivial (<0.20), small (0.20−0.49), medium (0.50−0.79), or large (≥0.80). Heterogeneity was interpreted based on the I2 statistics as low (25%), moderate (50%), or high (75%). Results: Pooled analyses showed no differences between exergaming and conventional CR programs for enhancing exercise capacity (i.e., distance covered in the six-minute walk test) (MD+ = 14.07 m (95% confidence interval (CI) −38.18 to 66.32 m); p = 0.426) and mental health (SMD+ = 0.17 (95% CI −0.36 to 0.70); p = 0.358). The results showed a small, statistically nonsignificant improvement in quality of life in favor of exergaming (SMD+ = 0.22 (95% CI = −0.37 to 0.81); p = 0.294). Moderate heterogeneity was found for exercise capacity (I2 = 53.7%), while no heterogeneity was found for quality of life (I2 = 3.3%) and mental health (I2 = 0.0%). Conclusions: Exergaming seems not to be superior to conventional CR programs for improving exercise capacity, quality of life, or mental health in patients with CVD.

Validation of the PROMIS-29v2 Health-Related Quality-of-Life Questionnaire in Patients With Coronary Heart Disease Participating in Remote Cardiac Rehabilitation

PURPOSE

The aim of this study was to validate the 29-item Patient-Reported Outcomes Measurement Information System version 2.0 (PROMIS-29v2) health-related quality-of-life (HRQL) questionnaire for use in patients with coronary heart disease (CHD) participating in remotely delivered cardiac rehabilitation (CR).

METHODS

Patients commencing remote CR across four sites in New South Wales, Australia, answered the PROMIS-29v2 and 12-item Short Form Health Survey version 2.0 (SF-12v2) questionnaires at CR entry and completion (6 wk). The data were analyzed for validity, reliability, and responsiveness to change.

RESULTS

Patients (N = 89) had a mean age of 66.9 ± 9.3 yr; 83% were male and were referred to CR for elective percutaneous coronary intervention (PCI) (42%), myocardial infarction (36%), and coronary artery bypass grafting (22%). Internal consistency reliability was adequate, with the Cronbach α ranging from 0.78-0.98. Convergent validity between the PROMIS-29v2 and SF-12v2 summary scores showed significantly strong correlations for physical (r = 0.62) and moderate for mental (r = 0.36) health. Discriminant validity was confirmed for sex (women reported lower physical and mental health) and referral diagnosis (patients who had elective PCI reported better physical health). Effect size (ES) comparisons confirmed responsiveness to change from CR entry to completion in physical health (ES = 0.51) and demonstrated evidence of more responsiveness than SF-12v2 for mental health (ES = 0.70).

CONCLUSION

The PROMIS-29v2 is reliable, valid, and responsive to changes in patients with CHD attending remotely delivered CR and allows for baseline HRQL assessment, between-diagnosis comparisons, and evaluation of changes over time.

OUP accepted manuscript

Aims

Enforced suspension and reduction of in-person cardiac rehabilitation (CR) services during the coronavirus disease-19 (COVID-19) pandemic restrictions required rapid implementation of remote delivery methods, thus enabling a cohort comparison of in-person vs. remote-delivered CR participants. This study aimed to examine the health-related quality of life (HRQL) outcomes and patient experiences comparing these delivery modes.

Methods and results

Participants across four metropolitan CR sites receiving in-person (December 2019 to March 2020) or remote-delivered (April to October 2020) programmes were assessed for HRQL (Short Form-12) at CR entry and completion. A General Linear Model was used to adjust for baseline group differences and qualitative interviews to explore patient experiences. Participants (n = 194) had a mean age of 65.94 (SD 10.45) years, 80.9% males. Diagnoses included elective percutaneous coronary intervention (40.2%), myocardial infarction (33.5%), and coronary artery bypass grafting (26.3%). Remote-delivered CR wait times were shorter than in-person [median 14 (interquartile range, IQR 10–21) vs. 25 (IQR 16–38) days, P < 0.001], but participation by ethnic minorities was lower (13.6% vs. 35.2%, P < 0.001). Remote-delivered CR participants had equivalent benefits to in-person in all HRQL domains but more improvements than in-person in Mental Health, both domain [mean difference (MD) 3.56, 95% confidence interval (CI) 1.28, 5.82] and composite (MD 2.37, 95% CI 0.15, 4.58). From qualitative interviews (n = 16), patients valued in-person CR for direct exercise supervision and group interactions, and remote-delivered for convenience and flexibility (negotiable contact times).

Conclusion

Remote-delivered CR implemented during COVID-19 had equivalent, sometimes better, HRQL outcomes than in-person, and shorter wait times. Participation by minority groups in remote-delivered modes are lower. Further research is needed to evaluate other patient outcomes.

Cardiac rehabilitation for older adults: current evidence and future potential

INTRODUCTION

Growth of the older adult demographic has resulted in an increased number of older patients with cardiovascular disease (CVD) in combination with comorbid diseases and geriatric syndromes. Cardiac rehabilitation (CR) is utilized to promote recovery and improve outcomes, but remains underutilized, particularly by older adults. CR provides an opportunity to address the distinctive needs of older adults, with focus on CVD as well as geriatric domains that often dominate management and outcomes.

AREAS COVERED

Utility of CR for CVD in older adults as well as pertinent geriatric syndromes (e.g. multimorbidity, frailty, polypharmacy, cognitive decline, psychosocial stress, and diminished function) that affect CVD management.

EXPERT OPINION

Mounting data substantiate the importance of CR as part of recovery for older adults with CVD. The application of CR as a standard therapy is especially important as the combination of CVD and geriatric syndromes catalyzes functional decline and can trigger progressive clinical deterioration and dependency. While benefits of CR for older adults with CVD are already evident, further reengineering of CR is necessary to better address the needs of older candidates who may be frail, especially as remote and hybrid formats of CR are becoming more widespread.

Health-Related Quality of Life and Its Influencing Factors in Patients with Coronary Heart Disease in China

PURPOSE

This study aimed to comprehensively evaluate Chinese coronary heart disease (CHD) patients' health-related quality of life (HRQoL) using various measures and explore influencing factors associated with HRQoL.

METHODS

A cross-sectional study was conducted from April to September 2019 in the General Hospital of Tianjin Medical University. A convenience sampling framework was used to successively recruit 316 inpatients with CHD. Two generic preference-based instruments (EQ-5D-5L and 15D), a disease-specific instrument (Seattle Angina Questionnaire, SAQ), and the WHO-5 well-being index (WHO-5) were administered. Tobit regression model and multiple linear regression were used for data analyses.

RESULTS

A total of 305 patients (mean age was 62.9) with CHD participated in this study. The mean health state utility (HSU) scores of EQ-5D-5L and 15D were 0.85 (SD=0.14) and 0.89 (SD=0.07), respectively. For EQ-5D-5L, pain/discomfort was the most frequently reported, followed by anxiety/depression. As for 15D, discomfort and symptoms was the most severely impaired dimension. For SAQ, more limitations were found in the domains of angina stability and disease perception. For WHO-5, the mean score was 16.93. Marital status, disease state and comorbidity were influencing factors associated with HRQoL, patient's subjective well-being had a positive impact on HRQoL.

CONCLUSION

To improve the HRQoL of CHD patients in China, more attention needs to be paid to unmarried and relapsed patients, especially those with comorbidity of hypertension. Additionally, more social support and psychological counseling should be provided to patients.

Effects of Supervised Cardiac Rehabilitation Programmes on Quality of Life among Myocardial Infarction Patients: A Systematic Review and Meta-Analysis

Coronary heart disease is the leading cause of death and disability worldwide. Traditionally, cardiac rehabilitation programmes are offered after cardiac events to aid recovery, improve quality of life, and reduce adverse events. The objective of this review was to assess the health-related quality of life, after a supervised cardiac rehabilitation programme, of patients who suffered a myocardial infarction. A systematic review was carried out in the CINAHL, Cochrane, LILACS, Medline, Scopus, and SciELO databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Randomised controlled trials were selected. Meta-analyses were performed for the Short Form Health Survey SF-36, Myocardial Infarction Dimensional Assessment Scale (MIDAS), MacNew Heart Disease-Health-Related Quality of Life (HRQL) questionnaire, and European Quality of Life-Visual Analogue Scale (EuroQol-VAS) with the software Cochrane RevMan Web. Ten articles were found covering a total of 3577 patients. In the meta-analysis, the effect size of the cardiac rehabilitation programme was statistically significant in the intervention group for physical activity, emotional reaction, and dependency dimensions of the MIDAS questionnaire. For the control group, the score improved for SF-36 physical functioning, and body pain dimensions. The mean difference between the control and intervention group was not significant for the remaining dimensions, and neither for the MacNew Heart Disease-HRQL and EuroQol-VAS questionnaires. Supervised cardiac rehabilitation programmes were effective in improving health-related quality of life, however, there was a potential variability in the interventions; therefore, the results should be interpreted with caution. This study supports the importance of providing care and evaluating interventions via the supervision of trained health professionals, and further randomised clinical trials are needed to analyse the positive changes in mental and physical health outcomes.

Effectiveness of nurse-led counselling and education on self-efficacy of patients with acute coronary syndrome: A randomized controlled trial

Aim

Adherence to lifestyle recommendations, medical regimens and cardiac rehabilitation is poor among patients with acute coronary syndrome. The aim of this study was to examine the effect of nurse‐led counselling and education using a person‐centred care approach on short‐term cardiac self‐efficacy in patients with acute coronary syndrome.

Design

A parallel, two‐armed, randomized controlled trial was conducted.

Methods

One hundred twenty patients who were hospitalized with diagnosis of acute coronary syndrome were selected and randomly assigned into intervention (n = 60) or control (n = 60) groups. In the intervention group, in addition to routine care, the nurse‐led counselling and education programme included two face‐to‐face sessions, two telephone counselling and education sessions, using the person‐centred care approach. Participants in the control group received only routine care. Data were collected using the cardiac self‐efficacy scale before the intervention and 1 month after discharge.

Results

After the intervention, we found that cardiac self‐efficacy, including the perceived self‐efficacy to control symptoms and maintain function, was statistically significantly higher in the intervention group than the control group.

Exercise-based cardiac rehabilitation for coronary heart disease

BACKGROUND

Coronary heart disease (CHD) is the most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people living with CHD may need support to manage their symptoms and prognosis. Exercise-based cardiac rehabilitation (CR) aims to improve the health and outcomes of people with CHD. This is an update of a Cochrane Review previously published in 2016.

OBJECTIVES

To assess the clinical effectiveness and cost-effectiveness of exercise-based CR (exercise training alone or in combination with psychosocial or educational interventions) compared with 'no exercise' control, on mortality, morbidity and health-related quality of life (HRQoL) in people with CHD.

SEARCH METHODS

We updated searches from the previous Cochrane Review, by searching CENTRAL, MEDLINE, Embase, and two other databases in September 2020. We also searched two clinical trials registers in June 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of exercise-based interventions with at least six months' follow-up, compared with 'no exercise' control. The study population comprised adult men and women who have had a myocardial infarction (MI), coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI), or have angina pectoris, or coronary artery disease.

DATA COLLECTION AND ANALYSIS

We screened all identified references, extracted data and assessed risk of bias according to Cochrane methods. We stratified meta-analysis by duration of follow-up: short-term (6 to 12 months); medium-term (> 12 to 36 months); and long-term ( > 3 years), and used meta-regression to explore potential treatment effect modifiers. We used GRADE for primary outcomes at 6 to 12 months (the most common follow-up time point).  MAIN RESULTS: This review included 85 trials which randomised 23,430 people with CHD. This latest update identified 22 new trials (7795 participants). The population included predominantly post-MI and post-revascularisation patients, with a mean age ranging from 47 to 77 years. In the last decade, the median percentage of women with CHD has increased from 11% to 17%, but females still account for a similarly small percentage of participants recruited overall ( < 15%). Twenty-one of the included trials were performed in low- and middle-income countries (LMICs). Overall trial reporting was poor, although there was evidence of an improvement in quality over the last decade. The median longest follow-up time was 12 months (range 6 months to 19 years). At short-term follow-up (6 to 12 months), exercise-based CR likely results in a slight reduction in all-cause mortality (risk ratio (RR) 0.87, 95% confidence interval (CI) 0.73 to 1.04; 25 trials; moderate certainty evidence), a large reduction in MI (RR 0.72, 95% CI 0.55 to 0.93; 22 trials; number needed to treat for an additional beneficial outcome (NNTB) 75, 95% CI 47 to 298; high certainty evidence), and a large reduction in all-cause hospitalisation (RR 0.58, 95% CI 0.43 to 0.77; 14 trials;  NNTB 12, 95% CI 9 to 21; moderate certainty evidence). Exercise-based CR likely results in little to no difference in risk of cardiovascular mortality (RR 0.88, 95% CI 0.68 to 1.14; 15 trials; moderate certainty evidence), CABG (RR 0.99, 95% CI 0.78 to 1.27; 20 trials; high certainty evidence), and PCI (RR 0.86, 95% CI 0.63 to 1.19; 13 trials; moderate certainty evidence) up to 12 months' follow-up. We are uncertain about the effects of exercise-based CR on cardiovascular hospitalisation, with a wide confidence interval including considerable benefit as well as harm (RR 0.80, 95% CI 0.41 to 1.59; low certainty evidence). There was evidence of substantial heterogeneity across trials for cardiovascular hospitalisations (I2 = 53%), and of small study bias for all-cause hospitalisation, but not for all other outcomes. At medium-term follow-up, although there may be little to no difference in all-cause mortality (RR 0.90, 95% CI 0.80 to 1.02; 15 trials), MI (RR 1.07, 95% CI 0.91 to 1.27; 12 trials), PCI (RR 0.96, 95% CI 0.69 to 1.35; 6 trials), CABG (RR 0.97, 95% CI 0.77 to 1.23; 9 trials), and all-cause hospitalisation (RR 0.92, 95% CI 0.82 to 1.03; 9 trials), a large reduction in cardiovascular mortality was found (RR 0.77, 95% CI 0.63 to 0.93; 5 trials). Evidence is uncertain for difference in risk of cardiovascular hospitalisation (RR 0.92, 95% CI 0.76 to 1.12; 3 trials). At long-term follow-up, although there may be little to no difference in all-cause mortality (RR 0.91, 95% CI 0.75 to 1.10), exercise-based CR may result in a large reduction in cardiovascular mortality (RR 0.58, 95% CI 0.43 to 0.78; 8 trials) and MI (RR 0.67, 95% CI 0.50 to 0.90; 10 trials). Evidence is uncertain for CABG (RR 0.66, 95% CI 0.34 to 1.27; 4 trials), and PCI (RR 0.76, 95% CI 0.48 to 1.20; 3 trials). Meta-regression showed benefits in outcomes were independent of CHD case mix, type of CR, exercise dose, follow-up length, publication year, CR setting, study location, sample size or risk of bias. There was evidence that exercise-based CR may slightly increase HRQoL across several subscales (SF-36 mental component, physical functioning, physical performance, general health, vitality, social functioning and mental health scores) up to 12 months' follow-up; however, these may not be clinically important differences. The eight trial-based economic evaluation studies showed exercise-based CR to be a potentially cost-effective use of resources in terms of gain in quality-adjusted life years (QALYs).

AUTHORS' CONCLUSIONS

This updated Cochrane Review supports the conclusions of the previous version, that exercise-based CR provides important benefits to people with CHD, including reduced risk of MI, a likely small reduction in all-cause mortality, and a large reduction in all-cause hospitalisation, along with associated healthcare costs, and improved HRQoL up to 12 months' follow-up. Over longer-term follow-up, benefits may include reductions in cardiovascular mortality and MI. In the last decade, trials were more likely to include females, and be undertaken in LMICs, increasing the generalisability of findings. Well-designed, adequately-reported RCTs of CR in people with CHD more representative of usual clinical practice are still needed. Trials should explicitly report clinical outcomes, including mortality and hospital admissions, and include validated HRQoL outcome measures, especially over longer-term follow-up, and assess costs and cost-effectiveness.

A co-designed telehealth-based model of care to improve attendance and completion to cardiac rehabilitation of rural and remote Australians: The Country Heart Attack Prevention (CHAP) project

We aim to report the co-design of the implementation strategy of a telehealth-enabled cardiac rehabilitation model of care in rural and remote areas of Australia. The goal of this model of care is to increase cardiac rehabilitation attendance and completion by country patients with cardiovascular diseases.We hypothesise that a model of care co-designed with stakeholders will address patients' needs and preferences and increase participation. We applied the Model for Large Scale Knowledge Translation and engaged with patients, clinicians and health service managers across six local health networks in rural South Australia. They informed the design of a web-based cardiac rehabilitation programme and the delivery of the expanded telehealth service.The stakeholders defined face-to-face, telephone, web-based or combinations as choices of mode of delivery to patients referred to cardiac rehabilitation. A case-managed programme supported by a web portal with an interface for patients and clinicians was considered more appropriate to the local context than a self-managed programme. A business model was developed to enable the sustainability of cardiac rehabilitation clinical assessments through primary care. The impact of the model of care on cardiac rehabilitation attendance/completion, clinical outcomes, patient-reported outcomes and patient-reported experiences and cost-effectiveness will be tested in a 12-month follow-up study.

A nationwide survey on participation in cardiac rehabilitation among patients with coronary heart disease using health claims data in Japan

Poor implementation and variable quality of cardiac rehabilitation (CR) for coronary heart disease (CHD) have been a global concern. This nationwide study aimed to clarify the implementation of and participation in CR among CHD patients and associated factors in Japan. We conducted a retrospective cohort study using data extracted from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. Patients who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in 2017-2018 were included. Aspects of CR were assessed in terms of (1) participation in exercise-based CR, (2) pharmacological education, and (3) nutritional education. Of 87,829 eligible patients, 32% had participated in exercise-based CR, with a mean program length of 40 ± 71 days. CABG was associated with higher CR participation compared to PCI (OR 10.2, 95% CI 9.6-10.8). Patients living in the Kyushu region were more likely to participate in CR (OR 2.59, 95% CI 2.39-2.81). Among patients who participated in CR, 92% received pharmacological education, whereas only 67% received nutritional education. In Japan, the implementation of CR for CHD is insufficient and involved varying personal, therapeutic, and geographical factors. CR implementation needs to be promoted in the future.

Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 2

Background: Scientific guidelines have been developed to update and harmonize exercise based cardiac rehabilitation (ebCR) in German speaking countries. Key recommendations for ebCR indications have recently been published in part 1 of this journal. The present part 2 updates the evidence with respect to contents and delivery of ebCR in clinical practice, focusing on exercise training (ET), psychological interventions (PI), patient education (PE). In addition, special patients’ groups and new developments, such as telemedical (Tele) or home-based ebCR, are discussed as well. Methods: Generation of evidence and search of literature have been described in part 1. Results: Well documented evidence confirms the prognostic significance of ET in patients with coronary artery disease. Positive clinical effects of ET are described in patients with congestive heart failure, heart valve surgery or intervention, adults with congenital heart disease, and peripheral arterial disease. Specific recommendations for risk stratification and adequate exercise prescription for continuous-, interval-, and strength training are given in detail. PI when added to ebCR did not show significant positive effects in general. There was a positive trend towards reduction in depressive symptoms for “distress management” and “lifestyle changes”. PE is able to increase patients’ knowledge and motivation, as well as behavior changes, regarding physical activity, dietary habits, and smoking cessation. The evidence for distinct ebCR programs in special patients’ groups is less clear. Studies on Tele-CR predominantly included low-risk patients. Hence, it is questionable, whether clinical results derived from studies in conventional ebCR may be transferred to Tele-CR. Conclusions: ET is the cornerstone of ebCR. Additional PI should be included, adjusted to the needs of the individual patient. PE is able to promote patients self-management, empowerment, and motivation. Diversity-sensitive structures should be established to interact with the needs of special patient groups and gender issues. Tele-CR should be further investigated as a valuable tool to implement ebCR more widely and effectively.

Post-COVID-19 Syndrome and the Potential Benefits of Exercise

The coronavirus disease (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection, is leading to unknown and unusual health conditions that are challenging to manage. Post-COVID-19 syndrome is one of those challenges, having become increasingly common as the pandemic evolves. The latest estimates suggest that 10 to 20% of the SARS-CoV-2 patients who undergo an acute symptomatic phase are experiencing effects of the disease beyond 12 weeks after diagnosis. Although research is beginning to examine this new condition, there are still serious concerns about the diagnostic identification, which limits the best therapeutic approach. Exercise programs and physical activity levels are well-known modulators of the clinical manifestations and prognosis in many chronic diseases. This narrative review summarizes the up-to-date evidence on post-COVID-19 syndrome to contribute to a better knowledge of the disease and explains how regular exercise may improve many of these symptoms and could reduce the long-term effects of COVID-19.

Multimodal Supervised Exercise Training Is Effective in Improving Long Term Walking Performance in Patients with Symptomatic Lower Extremity Peripheral Artery Disease

This study aimed to evaluate the effect of a multimodal supervised exercise training (SET) program on walking performance for 12 months in patients with symptomatic lower extremity peripheral artery disease (PAD). Consecutive patients with Fontaine stage II PAD participating in the SET program of our hospital were retrospectively investigated. Walking performance, assessed using a treadmill with measures of the pain-free and maximal walking distance (PFWD, MWD, respectively), and 6 min walking distance (6MWD), were tested before and following SET, as well as at 6 and 12 months after SET completion. Ninety-three symptomatic patients with PAD (65.0 ± 1.1 y) were included in the study. Following SET, the walking performance significantly improved (PFWD: +145%, p ≤ 0.001; MWD: +97%, p ≤ 0.001; 6MWD: +15%, p ≤ 0.001). At 6 months, PFWD (+257%, p ≤ 0.001), MWD (+132%, p ≤ 0.001), and 6MWD (+11%, p ≤ 0.001) remained significantly improved compared with the pre-SET condition. At 12 months, PFWD (+272%, p ≤ 0.001), MWD (+130%, p ≤ 0.001), and 6MWD (+11%, p ≤ 0.001) remained significantly improved compared with the pre-training condition. The walking performance remained significantly improved in both women and men for up to 12 months (p ≤ 0.001). Multimodal SET is effective at improving walking performance in symptomatic patients with PAD, with improvements lasting up to 12 months.

Health Literacy for Cardiac Rehabilitation: An Examination of Associated Illness Perceptions, Self-Efficacy, Motivation and Physical Activity

Following a diagnosis of cardiovascular disease there is a need for patients to self-manage. Health literacy has been shown to be lower in patients with cardiovascular disease, yet research into health literacy in this population is limited. This study used the Health Literacy Questionnaire (HLQ) to examine the health literacy and associated health, health behaviours and psychological profiles of cardiac rehabilitation patients from a remote and rural regional programme in the Scottish Highlands. Consecutive patients referred to the service in a calendar year were sent a cross-sectional questionnaire by post. Hierarchical cluster analysis grouped respondents based on their health literacy profile, and nonparametric methods were used to analyse differences between clusters on the other measures. A total of 282 participants responded (45.7%). Respondents were older (median: 71 years) and more likely to be from more affluent areas. Five health literacy clusters emerged with different profiles of health, physical activity, self-efficacy, motivation and illness perceptions. There was no difference in relation to cardiac rehabilitation attendance by health literacy cluster, but those with lower health literacy were less likely to be aware of the referral. Patterns of health literacy are associated with health, health behaviours and some psychological constructs. Knowledge of distinct cluster characteristics may help services better target interventions.

Cardiac rehabilitation in patients with peripheral arterial disease after revascularization

OBJECTIVES

To evaluate safety, feasibility, and benefit of cardiac rehabilitation (CR) in patients with peripheral arterial disease (PAD) who undergo revascularization.

METHODS

We conducted a prospective, non-randomized, pilot study to assess the feasibility, safety, and benefit of CR in PAD patients after revascularization compared to standard of care (controls). CR feasibility was assessed by the ability to complete 36 sessions. Safety was defined as the absence of adverse cardiovascular events during CR. Quality of life (QoL) assessment was performed using SF-36 form (Medical Outcomes Study 36-Item Short-Form Health Survey) and PAD-specific quality of life questionnaire (VascuQOL6). Other endpoints included incidence of claudication during 6-minute walk test (6MWT), mean distance, and number of laps walked. All outcome data were collected before and after CR completion. Standard statistical tests were used for comparisons.

RESULTS

This study enrolled 20 subjects (CR group = 10). Mean age was 60.70 (±7.13) and 63.1 (±9.17) years in CR and controls, respectively (p-value > 0.05). Fifty percent and 60% were female in CR and control group, respectively. All subjects completed 36 CR sessions without adverse events. The increase in mean distance walked during 6MWT was higher in the CR group compared to control group (63.7 m vs. 10.5 m, p = 0.043). Change in mean number of laps walked was higher in the CR group (3.5 vs. -1.1; p < 0.01). Scores on 6 of 8 scales of SF-36 and VascuQOL6 were higher in the CR group, though not statistically significant.

CONCLUSION

CR is safe, feasible, and improves walking ability in ambulatory patients with PAD after arterial revascularization.

Does contemporary exercise-based cardiac rehabilitation improve quality of life for people with coronary artery disease? A systematic review and meta-analysis

OBJECTIVES

To determine the effect of contemporary exercise-based cardiac rehabilitation on generic and disease-specific health related quality of life for people with coronary artery disease.

DESIGN

Systematic review and meta-analysis.

STUDY ELIGIBILITY CRITERIA

Randomised controlled trials testing exercise-based cardiac rehabilitation versus no exercise control that recruited after 31 December 1999. On 30 July 2019, we searched the Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), Embase (Ovid) and CINAHL (EBSCO) databases.

STUDY APPRAISAL AND SYNTHESIS

Studies were screened for inclusion by two independent reviewers. Risk of bias was assessed using the Cochrane risk of bias tool. Data were reported as pooled means (95% CI for between-group difference.

RESULTS

We identified 24 studies (n=4890). We performed meta-analyses for 15 short-term and 9 medium-term outcomes (36-Item Short Form Survey Instrument (SF-36), EuroQol-5D (EQ-5D) and MacNew, a cardiac-specific outcome). Six short-term and five medium-term SF-36 domains statistically favoured exercise-based cardiac rehabilitation. Only for two short-term SF-36 outcomes, 'physical function' (mean difference 12.0, 95% CI 4.4 to 19.6) and 'role physical' (mean difference 16.9, 95% CI 2.4 to 31.3), did the benefit appear to be clinically important. Meta-analyses of the short-term SF-36 physical and mental component scores, EQ-5D and MacNew and the medium-term SF-36 physical component score, did not show statistically significant benefits. Only two studies had a low risk of bias (n=463 participants).

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

There is some evidence of a short-term benefit of contemporary exercise-based cardiac rehabilitation on quality of life for people with coronary artery disease. However, the contemporary data presented in this review are insufficient to support its routine use.

Patient-reported outcomes predict return to work and health-related quality of life six months after cardiac rehabilitation: Results from a German multi-centre registry (OutCaRe)

BACKGROUND

Multi-component cardiac rehabilitation (CR) is performed to achieve an improved prognosis, superior health-related quality of life (HRQL) and occupational resumption through the management of cardiovascular risk factors, as well as improvement of physical performance and patients' subjective health. Out of a multitude of variables gathered at CR admission and discharge, we aimed to identify predictors of returning to work (RTW) and HRQL 6 months after CR.

DESIGN

Prospective observational multi-centre study, enrolment in CR between 05/2017 and 05/2018.

METHOD

Besides general data (e.g. age, sex, diagnoses), parameters of risk factor management (e.g. smoking, hypertension), physical performance (e.g. maximum exercise capacity, endurance training load, 6-min walking distance) and patient-reported outcome measures (e.g. depression, anxiety, HRQL, subjective well-being, somatic and mental health, pain, lifestyle change motivation, general self-efficacy, pension desire and self-assessment of the occupational prognosis using several questionnaires) were documented at CR admission and discharge. These variables (at both measurement times and as changes during CR) were analysed using multiple linear regression models regarding their predictive value for RTW status and HRQL (SF-12) six months after CR.

RESULTS

Out of 1262 patients (54±7 years, 77% men), 864 patients (69%) returned to work. Predictors of failed RTW were primarily the desire to receive pension (OR = 0.33, 95% CI: 0.22-0.50) and negative self-assessed occupational prognosis (OR = 0.34, 95% CI: 0.24-0.48) at CR discharge, acute coronary syndrome (OR = 0.64, 95% CI: 0.47-0.88) and comorbid heart failure (OR = 0.51, 95% CI: 0.30-0.87). High educational level, stress at work and physical and mental HRQL were associated with successful RTW. HRQL was determined predominantly by patient-reported outcome measures (e.g. pension desire, self-assessed health prognosis, anxiety, physical/mental HRQL/health, stress, well-being and self-efficacy) rather than by clinical parameters or physical performance.

CONCLUSION

Patient-reported outcome measures predominantly influenced return to work and HRQL in patients with heart disease. Therefore, the multi-component CR approach focussing on psychosocial support is crucial for subjective health prognosis and occupational resumption.
