Women's Cardiac Rehabilitation Barriers: Results of the International Council of Cardiovascular Prevention and Rehabilitation's First Global Assessment

Are the Cardiovascular Benefits and Potential Risks of Physical Activity and Exercise Dependent on Race, Ethnicity, or Sex?

Physical activity (PA) is established as a cornerstone of cardiovascular health, however, disparities in participation exist across sociocultural groups, which in turn affect cardiovascular outcomes. Evidence suggests that although the positive cardiovascular effects of exercise are consistent across populations, notable differences in the magnitude of these benefits exist for racial and ethnic minorities and the female sex. Women derive greater protection from PA compared with men, with reduced rates of sudden cardiac death. In this review we examine the complex interplay of race and/or ethnicity and sex on the cardiovascular benefits associated with PA and exercise, cardiovascular adaptations to exercise, risks of sudden cardiac death, and "excessive" volume of exercise. Understanding these factors is crucial for developing targeted interventions to promote cardiovascular health and offset disparities.

Psychometric validation of the Cardiac Rehabilitation Barriers Scale Revised (CRBS-R) for hybrid delivery

OBJECTIVE

To test the measurement properties of the revised version of the English Cardiac Rehabilitation Barriers Scale (CRBS-R), suitable for hybrid delivery, structural validity, internal reliability, as well as face, cross-cultural, construct and criterion validity were assessed.

DESIGN

Cross-sectional study, where participants completed an online survey via Qualtrics (2023-2024).

SETTING

Multicentre, with cardiac rehabilitation (CR) programmes recruiting patients globally; most patients stemmed from a hybrid programme in Iran and supervised programme in Brazil.

PARTICIPANTS

Participants include inpatients or outpatients with a cardiovascular diagnosis or procedure that is indicated for participation in CR.

MEASURES

In addition to sociodemographic and CR use items, the 21-item CRBS-R was administered. It assesses multilevel barriers and was revised based on a literature review. Responses range from 1 to 5, with higher scores indicating greater barriers.

RESULTS

235 patients participated from all 6 WHO regions. Items were rated as highly applicable, and open-ended responses revealing no key barriers were omitted, supporting face and cross-cultural validity. Cronbach's α for the total CRBS-R was 0.82. Principal components analysis resulted in the extraction of 4 components, which collectively accounted for 60.5% of the variance and were all internally consistent. Construct validity was supported by associations of total CRBS scores with work status (p=0.04), exercise history (p=0.01) and social support (p=0.03). Total CRBS-R scores were significantly lower in patients who were referred and enrolled versus those who were not (both p≤0.01), confirming criterion validity.

CONCLUSIONS

The CRBS-R is a reliable and valid scale comprising four subscales, applicable to hybrid CR across diverse settings. It can serve as a valuable tool to support identification of patient's CR barriers, to optimise secondary prevention utilisation globally.

A multi-site mixed-method evaluation of 'Cardiac College for Women' implementation: perspectives of cardiac rehabilitation patients and providers

A Cardiac College for Women curriculum was developed to address the dearth of women-focused cardiac rehabilitation (CR) education. This study investigated: (1) patient utilization of the education; (2) acceptability and applicability of the education; as well as (3) patient and CR providers' experiences implementing it. This was a multi-site, mixed-methods study. After baseline assessments at an academic CR program in two Canadian provinces, the 12 weekly 30 min structured in-person group education sessions were led by staff in the relevant discipline, with supporting online videos and written materials. Women reported their engagement with the education in weekly diaries, and completed a survey post-program. Semi-structured virtual interviews were held with willing participants and staff delivering the intervention. Transcripts were analyzed concurrently by two researchers independently via NVIVO using text condensation, followed by consensus reconciliation and multi-source validation. Forty patients participated in the women-focused education program, with 28 completing weekly diaries and 36 post-intervention surveys. Participants attended 80% of sessions (67%-89%). They spent an average of 30 min/week engaging additionally with the online education, with 83% rating the weekly content applicable (73%-100%). Overall acceptability was rated 4.3 ± 1.7/5. Twelve patients and 5 staff participated in interviews. Four themes were identified: contextual considerations, staffing and implementation issues, valued aspects, and suggestions for improvement. In conclusion, Cardiac College for Women was established as highly acceptable and applicable to patients, supporting their self-management. The women-specific CR education materials were also established as readily implementable by CR staff.

Gender differences in cardiac rehabilitation participation and outcomes: an 18-year retrospective study in Iran

BACKGROUND

Cardiac rehabilitation (CR) is crucial for addressing cardiovascular diseases globally, with a specific emphasis on gender differences. Despite its demonstrated benefits for women, there's limited acceptance globally, especially in low- and middle-income countries. The program aims to optimize risk factors and improve overall patient well-being.

METHODS

A cohort study was performed on those who were candidates for CR programs during 2001-2019. Assessments were performed within one week before and one week after the 8-week CR program. Age, sex, smoking status, clinical data, resting systolic and diastolic blood pressure (SBP and DBP, respectively), echocardiography and laboratory data were obtained. Functional capacity was evaluated using the international physical activity questionnaire, and a treadmill exercise test. Anxiety, depression, general quality of life (QoL), and health-related QoL were selected for psychological status. Then statistical analysis was performed on data.

RESULT

In this study, the number of male patients was 1526 (73.69%). The average age of patients in the female group was higher than that of males (58.66 ± 9.08 vs. 56.18 ± 9.94), according to the crude model results, the changes in emotional, social and physical scores were significant (P-value:0.028, 0.018, 0.030), as well as the differences in Mets and smoking were significant (P-value for both < 0.001) in the adjusted model, the emotional variables and Mets changes were significant in two groups, so that the emotional score in the female group was higher than that of the male group, and the female Mets score was significantly lower than that of the male group.

CONCLUSION

The CR program can improve cardiovascular outcomes, but the greatest impact was on the quality of life, patient METs and smoking behavers. Also the number of female participants in the CR program was less than the number of males.

Sex and gender specific pitfalls and challenges in cardiac rehabilitation: a working hypothesis towards better inclusivity in cardiac rehabilitation programmes

Notwithstanding its acknowledged pivotal role for cardiovascular prevention, cardiac rehabilitation (CR) is still largely under prescribed, in almost 25% of patients owing an indication for. In addition, when considering differences concerning the two sexes, female individuals are underrepresented in CR programmes with lower referral rates, participation, and completion as compared to male counterpart. This picture becomes even more tangled with reference to gender, a complex socio-cultural construct characterized by four domains (gender identity, relation, role, and institutionalized gender). Indeed, each of them reveals several obstacles that considerably penalize CR adherence for different categories of people, especially those who are not identifiable with a non-binary gender. Aim of the present review is to identify the sex- (i.e. biological) and gender- (i.e. socio-cultural) specific obstacles to CR related to biological sex and sociocultural gender and then envision a likely viable solution through tailored treatments towards patients' well-being.

Effects of a brief intervention based on Acceptance and Commitment Therapy versus usual care for cardiac rehabilitation patients with coronary heart disease (ACTonHEART): a randomised controlled trial

OBJECTIVES

The main objective of the study is to investigate the short-term efficacy of Acceptance and Commitment Therapy (ACT) on the simultaneous modification of biological indicators of risk and psychological well-being in patients with coronary heart disease attending cardiac rehabilitation (CR).

DESIGN

This was a two-arm randomised controlled trial comparing a brief, manualised, ACT-based intervention with usual care (UC).

SETTING

The study was conducted in an outpatient CR unit in Italy. Data collection took place from January 2016 to July 2017.

PARTICIPANTS

Ninety-two patients were enrolled and randomised, following an unbalanced randomisation ratio of 2:1 to the ACT group (n=59) and the control group (n=33). Eighty-five patients completed the ACT (n=54) and the UC (n=31) interventions and were analysed.

INTERVENTIONS

The control group received UC, a 6 weeks multidisciplinary outpatient CR programme, encompassing exercise training, educational counselling and medical examinations. The experimental group, in addition to UC, participated in the Acceptance and Commitment Therapy on HEART disease (ACTonHEART) intervention encompassing three group sessions based on ACT.

OUTCOMES

The primary outcomes were Low Density Lipoproteins (LDL)cholesterol, resting systolic blood pressure, body mass index (BMI) and psychological well-being measured by the Psychological General Well-Being Index (PGWBI). Outcome measures were assessed at baseline and at the end of CR.

RESULTS

Based on linear mixed models, no significant group × time interaction was observed for either the primary outcomes (β, 95% CI: PGWBI =-1.13, -6.40 to -4.14; LDL cholesterol =-2.13, -11.02 to -6.76; systolic blood pressure =-0.50, -10.76 to -9.76; diastolic blood pressure =-2.73, -10.12 to -4.65; BMI =-0.16, -1.83 to -1.51, all p values >0.05) or the secondary outcomes (all p values >0.05). A significant time effect was found for the PGWBI total (beta=4.72; p=0.03).

CONCLUSIONS

Although analyses revealed null findings, the results can inform the design of future ACT-based CR interventions and can help researchers to strike a balance between the idealised implementation of an ACT intervention and the structural limitations of existing CR programmes.

Comprehensive and personalized approach is a critical area for developing remote cardiac rehabilitation programs

In the evolving landscape of cardiac rehabilitation (CR), adopting digital technologies, including synchronous/real-time digital interventions and smart applications, has emerged as a transformative approach. These technologies offer real-time health data access, continuous vital sign monitoring, and personalized educational enhanced patient self-management and engagement. Despite their potential benefits, challenges and limitations exist, necessitating careful consideration. Synchronous/real-time digital CR involves remote, two-way audiovisual communication, addressing issues of accessibility and promoting home-based interventions. Smart applications extend beyond traditional healthcare, providing real-time health data and fostering patient empowerment. Wearable devices and mobile apps enable continuous monitoring, tracking of rehabilitation outcomes, and facilitate lifestyle modifications crucial for cardiac health maintenance. As digital CR progresses, ensuring patient access, equitable implementation, and addressing the digital divide becomes paramount. Artificial intelligence holds promise in the early detection of cardiac events and tailoring patient-specific CR programs. However, challenges such as digital literacy, data privacy, and security must be addressed to ensure inclusive implementation. Moreover, the shift toward digital CR raises concerns about cost, safety, and potential depersonalization of therapeutic relationships. A transformative shift towards technologically enabled CR necessitates further research, focusing not only on technological advancements but also on customization to meet diverse patient needs. Overcoming challenges related to cost, safety, data security, and potential depersonalization is crucial for the widespread adoption of digital CR. Future studies should explore integrating moral values into digital therapeutic relationships and ensure that digital CR is accessible, equitable, and seamlessly integrated into routine cardiac care. Theoretical frameworks that accommodate the dynamic quality of real-time monitoring and feedback feature of digital CR interventions should be considered to guide intervention development.

Targeting behavioral factors with digital health and shared decision-making to promote cardiac rehabilitation-a narrative review

Cardiac rehabilitation (CR) represents an important steppingstone for many cardiac patients into a more heart-healthy lifestyle to prevent premature death and improve quality of life years. However, CR is underutilized worldwide. In order to support the development of targeted digital health interventions, this narrative review (I) provides understandings of factors influencing CR utilization from a behavioral perspective, (II) discusses the potential of digital health technologies (DHTs) to address barriers and reinforce facilitators to CR, and (III) outlines how DHTs could incorporate shared decision-making to support CR utilization. A narrative search of reviews in Web of Science and PubMed was conducted to summarize evidence on factors influencing CR utilization. The factors were grouped according to the Behaviour Change Wheel. Patients' Capability for participating in CR is influenced by their disease knowledge, awareness of the benefits of CR, information received, and interactions with healthcare professionals (HCP). The Opportunity to attend CR is impacted by healthcare system factors such as referral processes and HCPs' awareness, as well as personal resources including logistical challenges and comorbidities. Patients' Motivation to engage in CR is affected by emotions, factors such as gender, age, self-perception of fitness and control over the cardiac condition, as well as peer comparisons. Based on behavioral factors, this review identified intervention functions that could support an increase of CR uptake: Future DHTs aiming to support CR utilization may benefit from incorporating information for patients and HCP education, enabling disease management and collaboration along the patient pathway, and enhancing social support from relatives and peers. To conclude, considerations are made how future innovations could incorporate such functions.

Women-Focused Cardiac Rehabilitation Delivery Around the World and Program Enablers to Support Broader Implementation

Background

Women are less likely than men to use cardiac rehabilitation (CR); thus, women-focused (W-F) CR was developed. Implementation of W-F CR globally was investigated, as well as barriers and enablers to its delivery.

Methods

In this cross-sectional study, a survey was administered to CR programs via Research Electronic Data Capture (REDCap) from May to July, 2023. Potential respondents were identified via the International Council of Cardiovascular Prevention and Rehabilitation's network.

Results

A total of 223 responses were received from 52 of 111 countries (46.8% country response rate) in the world that have any CR, across all 6 World Health Organization regions. Thirty-three programs (14.8%) from 30 countries reported offering any W-F programming. Programs commonly did offer elements preferred by women and recommended, namely, the following: patient choice of session time (n = 151; 70.6%); invitations for informal care providers and/or partners to attend sessions (n = 121; 57.1%); CR staff that have expertise in women and heart diseases (n = 112; 53.3%); separate changerooms for women (n = 38; 52.8%); and discussion of CR referral with patients (n = 112; 52.1%). Main barriers to delivery of W-F exercise were physical resources (n = 33; 14.8%), space (n = 30; 13.5%), and staff time (n = 26; 11.7%) and expertise (n = 33; 10.3%). Main barriers to delivery of W-F education were human resources (n = 114; 51.1%), educational resources (n = 26; 11.7%), and expertise in the content (n = 74; 33.2%). Enablers of W-F education delivery were availability of materials, in multiple modalities, as well as educated staff and financial resources.

Conclusions

Despite the benefits, W-F CR is not commonly offered globally. Considering the barriers and enablers identified, the International Council of Cardiovascular Prevention and Rehabilitation is developing resources to expand delivery.

Quo vadis cardiac rehabilitation; the role of comprehensive cardiac rehabilitation in modern cardiology

In accordance with the guidelines established by prominent European and global cardiology associations, comprehensive cardiac rehabilitation (CR) stands as an officially endorsed and highly recommended therapeutic approach (class I recommendations; level of evidence A) for a diverse spectrum of cardiac patients. Nevertheless, it is a cause for concern to observe that fewer than 50% of eligible patients are being effectively referred for CR, whether in an outpatient or inpatient setting. Concurrently, studies reveal that a substantial proportion of individuals with atherosclerotic cardiovascular disease maintain unhealthy lifestyles and exhibit suboptimal management of modifiable cardiovascular risk factors, including hypertension, lipid levels, and diabetes. Beyond the conventional patient profile encompassing those recovering from acute coronary syndrome with or without percutaneous coronary intervention, as well as patients who have undergone coronary or valvular surgery, contemporary CR now emphasizes specialized subgroups of patients. These include frail elderly patients, the female population with its unique considerations, individuals burdened by multiple cardiovascular comorbidities, those who have developed psychological consequences due to a cardiac illness and particularly those grappling with chronic heart failure. This editorial seeks to offer a state-of-the-art assessment of the significance and role of comprehensive CR within modern cardiology.

"Challenges to Normalcy"- Perceived Barriers to Adherence to Home-Based Cardiac Rehabilitation Exercise in Patients with Chronic Heart Failure

Purpose

The aim of this study was to explore perceived barriers to adherence to home-based cardiac rehabilitation exercise in patients with chronic heart failure.

Patients and Methods

A qualitative descriptive study was conducted in this study from May to July 2023. A purposive sampling approach was adopted to select patients with chronic heart failure. Semi-structured interviews were completed to collect qualitative data for exploring the perceived barriers. In addition, information saturation and validation strategies were adopted to prove the adequacy of qualitative data. Transcripts were analysed using thematic analysis.

Results

A total of 16 patients with chronic heart failure were included in this study. Analysis of the data revealed five main barriers to adherence to home-based cardiac rehabilitation in patients with chronic heart failure. These include (1) lack of knowledge, (2) activity intolerance, (3) exercise fear, (4) role conflict, and (5) lower exercise self-efficacy.

Conclusion

This study delved deeper into understanding the challenges faced by chronic heart failure patients in adhering to home-based cardiac rehabilitation exercise. The development of precise and effective management and intervention strategies based on these barriers is necessary to improve patient compliance with home-based cardiac rehabilitation exercise.

Examining the effectiveness of home-based cardiac rehabilitation programs for heart failure patients with reduced ejection fraction: a critical review

BACKGROUND

Heart failure (HF) is the most common cardiovascular reason for hospital admission, particularly among patients older than 60 years old. Heart failure with reduced ejection fraction (HFrEF) comprises approximately 50% of all heart failure cases. Home-based cardiac rehabilitation (HBCR) is an alternative option to enhance the participation rate in cardiac rehabilitation (CR) interventions for patients who are not able to attend center-based cardiac rehabilitation (CBCR). The purpose of this review is to clarify the extent to which present studies of HBCR align with the core components defined by both the European Society of Cardiology (ESC) and the British Association for Cardiac Prevention and Rehabilitation (BACPR).

METHODS

A critical review was conducted through four databases, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews, to identify randomized controlled trials up until June 2022. We scrutinized the commonalities between BACPR and ESC and developed a list of standards. The risk of bias was assessed using the RoB 2 tool.

RESULTS

Among the 87 papers selected for full-text screening, 11 studies met the inclusion criteria. Six papers possessed a high proportion of fidelity to essential standards, four studies had a medium alliance, and one intervention had a low level of alliance.

CONCLUSION

Overall, the majority of included studies had medium to high alignment with standards and core components. However, a need for more attention to long-term strategy as an important standard is revealed. Rapid identification and initial assessment are the most met standards; however, lifestyle risk factor management and long-term outcomes were recognized as the least met standards.

The effects of CPET-guided cardiac rehabilitation on exercise tolerance in older persons with CHD after PCI

Prescribing appropriate exercise is an important means to improve the safety and efficacy of cardiac rehabilitation. Improper exercise may induce an increased cardiovascular risk in older persons with coronary heart disease. Cardiopulmonary exercise testing (CPET)-guided cardiac rehabilitation could be helpful for providing clinical evidence for cardiac rehabilitation therapy in older persons after percutaneous coronary intervention (PCI). We retrospectively included older persons who underwent PCI and cardiac rehabilitation based on CPET at the Cardiac Rehabilitation Center of Peking University Third Hospital from January 2014 to December 2019. Patients' baseline and follow-up clinical data were collected. A total of 403 older persons after PCI were included in the study. The mean age was 80.5 ± 4.3. The mean follow-up time was 12 ± 2 months. During the follow-up period, no significant exercise-related adverse events occurred, and the peak oxygen uptake (VO2peak) increased compared with baseline (15.5 ± 3.8 ml/min/kg vs. 17.3 ± 4.1 ml/min/kg). Among the 90 patients (22.2%) without exercise habits at baseline who started regular exercise during follow-up, the improvement in VO2peak was most significant, at 3.2 ± 0.4 ml/min/kg. Cardiac rehabilitation based on CPET improved exercise habits and exercise tolerance in older persons with coronary heart disease after PCI.
