Cardiac Rehabilitation for Women

Relationship Between Participation of In-Hospital Cardiac Rehabilitation and Regional Characteristics in Japan - Insight From the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination

Background

The influence of various regional backgrounds on participation in cardiac rehabilitation (CR) remains underexplored. We investigated the regional characteristics that potentially promote CR participation.

Methods and Results

This was a nationwide cross-sectional cohort study using the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination. This study included a cohort of 2.7 million inpatients hospitalized between April 2012 and March 2021. The CR participation rate for each hospital was calculated as the percentage of eligible patients who underwent CR during their admission. Among all hospitals, those that do not perform CR were defined as No-CR hospitals. The remaining hospitals were categorized into High- and Low-CR hospitals based on the median level of the CR participation rate (41.5%). High-CR hospitals had significantly smaller medical service areas (P<0.0001), a higher number of physicians per population (P<0.0001), higher air temperature (P=0.02), and fewer primary industry workers (P=0.005) than the other 2 groups. Logistic regression analyses revealed that a lower consumer price index was a significant regional factor that characterized High-CR hospitals, and a lower population aged ≥65 years was a factor approaching significance that characterized the region where High-CR hospitals are located.

Conclusions

High-CR hospitals were found in regions with a lower consumer price index and a trend towards a lower population aged ≥65 years.

Supra-normal and mildly reduced ejection fraction in women -An overlooked vulnerable subpopulation in heart failure

BACKGROUND

Recently, patients with supra-normal left ventricular ejection fraction (snEF) are reported to have high risk of adverse outcomes, especially in women. We sought to evaluate sex-related differences in the association between LVEF and long-term outcomes in heart failure (HF) patients.

METHODS

The multicenter WET-HF Registry enrolled all patients hospitalized for acute decompensated HF (ADHF). We analyzed 3943 patients (age 77 years; 40.1% female) registered from 2006 to 2017. According to LVEF the patients were divided into the 3 groups: HF with reduced EF (HFrEF), mildly reduced EF (HFmrEF) and preserved EF. The primary endpoint was defined as the composite of cardiac death and ADHF rehospitalization after discharge.

RESULTS

In HFmrEF, implementation of guideline-directed medical therapy (GDMT) such as the combination of renin-angiotensin-system inhibitor (RASi) and β-blocker at discharge was significantly lower in women than men even after adjustment for covariates (p = 0.007). There were no such sex-related differences in HFrEF. Female sex was associated with higher incidence of the primary endpoint and ADHF rehospitalization after adjustment for covariates exclusively in HFmrEF. Restricted cubic spline analysis demonstrated a U-shaped relationship between LVEF and the hazard ratio of the primary endpoint showing higher event rate in HFmrEF and HFsnEF in women, but such relationship was not observed in men (p for interaction = 0.037).

CONCLUSIONS

In women, mrEF and snEF were associated with worse long-term outcomes. Additionally, sex-related differences in the GDMT implementation for HFmrEF highlight the need for further exploration, which might lead to creation of sex-specific guidelines to optimize HF management.

Intensive Cardiac Rehabilitation Attenuates the Gender Gap in Cardiac Rehabilitation Participation

INTRODUCTION

Traditional cardiac rehabilitation programs historically have had considerable gender gaps in cardiac rehabilitation (CR) outcomes. Intensive-Cardiac-Rehabilitation (ICR) has non-exercise components such as stress management, peer support and diet modification, in addition to exercise, which may reduce barriers to CR completion. However, there is a paucity of data in ICR outcomes based on gender.

METHODS

We conducted a nationwide retrospective cohort study of 15,613 patients enrolled in 46 Ornish-ICR programs across the US from January 2016 - December 2020 and compared ICR physical and psychological outcomes in women versus men. Primary endpoints were depression scores (CESD), health status (SF-36 physical and mental composite-scores) and exercise minutes per week.

RESULTS

Of 15,613 ICR participants who participated in the program, 6788 (44%) were women. ICR completion rates were 64.7% overall and nearly equal between men and women (63.3% women vs 65.9% men). There were a few small differences in outcomes after ICR completion: women had slightly more improvement in depression scores (women: -6.10 ± 8.79, 49.6% reduction vs. men: -4.92 ± 7.80, 46.4% reduction; P<0.01) and SF-36 physical (women: 5.95±6.86 vs men: 5.28±6.71, P<0.01) and SF-36 mental (women: 5.76±8.11 vs men: 4.60±7.33, P<0.01) composite scores than men. There was no significant difference in exercise-minutes per week between the two groups.

CONCLUSIONS

ICR attenuates the gender gap in cardiac rehabilitation completion. Further, of the completers, women achieved slightly higher depression and quality-of-life improvements compared to men. As such, ICR can be a good option to reduce gender-based differences in CR participation.

Outcomes and cost of women-focused cardiac rehabilitation: A systematic review and meta-analysis

BACKGROUND

The aim of this systematic review was to investigate the effects of women-focused cardiac rehabilitation (CR) on patient outcomes and cost.

METHODS

Medline, PubMed, Embase, PsycINFO, CINAHL, Web of Science, Scopus and Emcare were searched for articles from inception through to May 2020. Primary studies of any design were included, with adult females with any cardiac diseases. "Women-focused" CR comprised programs or sessions with >50% females, or 1-1 programming tailored to women's preferences. No studies were excluded on the basis of outcome. Two independent reviewers rated citations for potential inclusion, and one extracted data, including on quality, which was checked independently. Random-effects meta-analysis was used where there were ≥3 trials with the same outcome; certainty of evidence for these was determined based on GRADE. For other outcomes, SWiM was applied.

RESULTS

3498 unique citations were identified, of which 28 studies (52 papers) were included (3,697 participants; 11 trials). No meta-analysis could be performed for outcomes with "usual care" comparisons. Compared to "active comparison" group, women-focused CR had no meaningful additional effect on functional capacity. Women-focused CR meaningfully improved physical (mean difference [MD]=6.37, 95% confidence interval [CI]=3.14-9.59; I2=0%; moderate-quality evidence) and mental (MD=4.66, 95% CI=0.21-9.11; I2=36%; low-quality evidence) quality of life, as well as scores on seven of the eight SF-36 domains. Qualitatively, results showed women-focused CR was associated with lower morbidity, risk factors, and greater psychosocial well-being. No effect was observed for mortality. One study reported a favorable economic impact and another reported reduced sick days.

CONCLUSIONS

Women-focused CR is associated with clinical benefit, although there is mixed evidence and more research is needed.

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

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

Nature, availability, and utilization of women-focused cardiac rehabilitation: a systematic review

Background

Women do not participate in cardiac rehabilitation (CR) to the same degree as men; women-focused CR may address this. This systematic review investigated the: (1) nature, (2) availability, as well as (3a) utilization of, and (b) satisfaction with women-focused CR.

Methods

Medline, Pubmed, Embase, PsycINFO, CINAHL, Web of Science, Scopus and Emcare were searched for articles from inception to May 2020. Primary studies of any design were included. Adult females with any cardiac diseases, participating in women-focused CR (i.e., program or sessions included ≥ 50% females, or was 1-1 and tailored to women’s needs) were considered. Two authors rated citations for inclusion. One extracted data, including study quality rated as per the Mixed-Methods Assessment Tool (MMAT), which was checked independently by a second author. Results were analyzed in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guideline.

Results

3498 unique citations were identified, with 28 studies (53 papers) included (3697 women; ≥ 10 countries). Globally, women-focused CR is offered by 40.9% of countries that have CR, with 32.1% of programs in those countries offering it. Thirteen (46.4%) studies offered women-focused sessions (vs. full program), 17 (60.7%) were women-only, and 11 (39.3%) had gender-tailoring. Five (17.9%) programs offered alternate forms of exercise, and 17 (60.7%) focused on psychosocial aspects. With regard to utilization, women-focused CR cannot be offered as frequently, so could be less accessible. Adherence may be greater with gender-tailored CR, and completion effects are not known. Satisfaction was assessed in 1 trial, and results were equivocal.

Conclusions

Women-focused CR involves tailoring of content, mode and/or sex composition. Availability is limited. Effects on utilization require further study.

Sex differences in psychosocial and cardiometabolic health among patients completing cardiac rehabilitation

Current programs of cardiac rehabilitation (CR) typically provide a standardized approach to all patients. We examined whether CR would produce similar improvements in psychosocial and cardiometabolic health indicators in women compared with men. The records of patients who completed a 3-month outpatient CR program were examined. We compared health-related quality of life (i.e., Physical Component Summary (PCS) and Mental Component Summary (MCS) scores), anxiety, depression, and cardiometabolic health indicators between women and men completing CR. Of the 591 participants who completed CR, 155 (26.2%) were women and 436 (73.8%) were men. At baseline, women were older (64 ± 9 vs. 62 ± 9 years, p = 0.045), had lower PCS (39.5 ± 8.1 vs. 43.9 ± 7.8 points, p < 0.001), and MCS (46.6 ± 10.8 vs. 49.4 ± 9.8 points, p = 0.003) scores, experienced elevated levels of anxiety (6.4 ± 4.0 vs. 5.2 ± 4.0 points, p = 0.001) and depression (4.7 ± 3.5 vs. 3.6 ± 3.3 points, p = 0.001), and had higher low-density lipoprotein cholesterol (2.1 ± 0.9 vs. 1.7 ± 0.7 mmol/L, p < 0.001) and high-density lipoprotein cholesterol (1.4 ± 0.4 vs. 1.1 ± 0.3 mmol/L, p < 0.001) concentrations when compared with men. Following CR, women showed smaller improvements in percent body mass (+1.1% ± 10.1% vs. −2.1% ± 9.7%, p = 0.002) and PCS scores (3.0 ± 8.1 vs. 6.3 ± 7.5 points, p < 0.001) when compared with men. Considering poorer psychosocial health at baseline and smaller improvements in health-related quality of life in women when compared with men, more specific CR strategies addressing the particular needs of women are required to improve their health status and reduce the risk of secondary cardiac events.
