Association of Home-Based Cardiac Rehabilitation With Lower Mortality in Patients With Cardiovascular Disease: Results From the Veterans Health Administration Healthy Heart Program.

Background Home-based cardiac rehabilitation (HBCR) and traditional facility-based cardiac rehabilitation (CR) programs have similar effects on mortality in clinical trials and meta-analyses. However, the effect of HBCR on mortality in clinical practice settings is less clear. Therefore, we sought to compare mortality rates in HBCR participants versus nonparticipants. Methods and Results We evaluated all patients who were referred to and eligible for outpatient CR between 2013 and 2018 at the San Francisco Veterans Health Administration. Patients who chose to attend facility-based CR and those who died within 30 days of hospitalization were excluded. Patients who chose to participate in HBCR received up to 9 telephonic coaching and motivational interviewing sessions over 12 weeks. All patients were followed through June 30, 2021. We used Cox proportional hazards regression models with inverse probability treatment weighting to compare mortality in HBCR participants versus nonparticipants. Of the 1120 patients (mean age 68, 98% male, 76% White) who were referred and eligible, 490 (44%) participated in HBCR. During a median follow-up of 4.2 years, 185 patients (17%) died. Mortality was lower among the 490 HBCR participants versus the 630 nonparticipants (12% versus 20%; P<0.01). In an inverse probability weighted Cox regression analysis adjusted for patient demographics and comorbid conditions, the hazard of mortality remained 36% lower among HBCR participants versus nonparticipants (hazard ratio, 0.64 [95% CI, 0.45-0.90], P=0.01). Conclusions Among patients eligible for CR, participation in HBCR was associated with 36% lower hazard of mortality. Although unmeasured confounding can never be eliminated in an observational study, our findings suggest that HBCR may benefit patients who cannot attend traditional CR programs.

Healthy hearts healthy minds: A randomized trial of online interventions to improve physical activity.

INTRODUCTION: Depressed individuals are more likely to die from cardiovascular disease (CVD) than those without depression. People with CVD have higher rates of depression than those without and have higher mortality rates if they have comorbid depression. While physical activity (PA) improves both, few people engage in enough. We compared self-guided internet-based cognitive behavior therapy (CBT) + Fitbit or mindfulness-based cognitive therapy (MBCT) + Fitbit, with Fitbit only to increase daily steps for participants with depression who have low PA. METHODS: Adult participants (N = 340) were recruited from two online patient-powered research networks and randomized to one of three study interventions for 8 weeks with an additional 8 weeks of follow-up. Using linear mixed effects models, we evaluated the effect of the intervention on average daily steps (NCT03373110). RESULTS: Average daily steps increased 2.8 steps per day in MBCT+Fitbit, 2.9 steps/day in CBT + Fitbit, but decreased 8.2 steps/day in Fitbit Only. These changes were not statistically different between the MBCT+Fitbit and CBT + Fitbit groups, but were different from Fitbit Only across the initial 8-week period. Group differences were not maintained across follow-up. Exploratory analyses identified comorbid anxiety disorders, self-reported PA, and employment status as moderators. DISCUSSION: Changes in daily steps over both 8- and 16-week periods-regardless of intervention group-were minimal. The results emphasize the limits of using self-guided web-based psychotherapy with an activity tracker to increase PA in participants with a history of depression and low PA.

Implementing the National Heart, Lung, and Blood Institute's Strategic Vision in the Division of Cardiovascular Sciences-2022 Update.

Spurred by the 2016 release of the National Heart, Lung, and Blood Institute's Strategic Vision, the Division of Cardiovascular Sciences developed its Strategic Vision Implementation Plan-a blueprint for reigniting the decline in cardiovascular disease (CVD) mortality rates, improving health equity, and accelerating translation of scientific discoveries into better cardiovascular health (CVH). The 6 scientific focus areas of the Strategic Vision Implementation Plan reflect the multifactorial nature of CVD and include (1) addressing social determinants of CVH and health inequities, (2) enhancing resilience, (3) promoting CVH and preventing CVD across the lifespan, (4) eliminating hypertension-related CVD, (5) reducing the burden of heart failure, and (6) preventing vascular dementia. This article presents an update of strategic vision implementation activities within Division of Cardiovascular Sciences. Overarching and cross-cutting themes include training the scientific workforce and engaging the extramural scientific community to stimulate transformative research in cardiovascular sciences. In partnership with other NIH Institutes, Federal agencies, industry, and the extramural research community, Division of Cardiovascular Sciences strategic vision implementation has stimulated development of numerous workshops and research funding opportunities. Strategic Vision Implementation Plan activities highlight innovative intervention modalities, interdisciplinary systems approaches to CVD reduction, a life course framework for CVH promotion and CVD prevention, and multi-pronged research strategies for combatting COVID-19. As new knowledge, technologies, and areas of scientific research emerge, Division of Cardiovascular Sciences will continue its thoughtful approach to strategic vision implementation, remaining poised to seize emerging opportunities and catalyze breakthroughs in cardiovascular sciences.

A Review of the Design and Implementation of a Hybrid Cardiac Rehabilitation Program: AN EXPANDING OPPORTUNITY FOR OPTIMIZING CARDIOVASCULAR CARE.

PURPOSE: This review describes the considerations for the design and implementation of a hybrid cardiac rehabilitation (HYCR) program, a patient-individualized combination of facility-based cardiac rehabilitation (FBCR) with virtual cardiac rehabilitation (CR) and/or remote CR. REVIEW METHODS: To help meet the goal of the Millions Hearts Initiative to increase CR participation to 70% by 2022, a targeted review of the literature was conducted to identify studies pertinent to the practical design and implementation of an HYCR program. Areas focused upon included the current use of HYCR, exercise programming considerations (eligibility and safety, exercise prescription, and patient monitoring), program assessments and outcomes, patient education, step-by-step instructions for billing and insurance reimbursement, patient and provider engagement strategies, and special considerations. SUMMARY: A FBCR is the first choice for patient participation in CR, as it is supported by an extensive evidence base demonstrating effectiveness in decreasing cardiac and overall mortality, as well as improving functional capacity and quality of life. However, to attain the CR participation rate goal of 70% set by the Million Hearts Initiative, CR programming will need to be expanded beyond the confines of FBCR. In particular, HYCR programs will be necessary to supplement FBCR and will be particularly useful for the many patients with geographic or work-related barriers to participation in an FBCR program. Research is ongoing and needed to develop optimal programming for HYCR.

Longitudinal Association Between Angina Pectoris and Quality of Life.

Angina is a common symptom in patients with coronary artery disease (CAD); however, its impact on patients' quality of life over time is not well understood. We sought to determine the longitudinal association of angina frequency with quality of life and functional status over a 5-year period. We used data from the Heart and Soul Study, a prospective cohort study of 1,023 outpatients with stable CAD. Participants completed the Seattle Angina Questionnaire (SAQ) at baseline and annually for 5 years. We evaluated the population effect of angina frequency on disease-specific quality of life (SAQ Disease Perception), physical function (SAQ Physical Limitation), perceived overall health, and overall quality of life, with adjusted models. We evaluated these associations within the same year and with a time-lagged association between angina and quality of life reported 1 year later. Generalized estimating equation models were used to account for repeated measures and within-subject correlation of responses. Over 5 years of follow-up, patients with daily or weekly angina symptoms had lower quality of life scores (52 vs 89, p <0.001) and greater physical limitation (61 vs 86, p <0.001) after adjustment. Compared with patients with daily or weekly angina symptoms, those with no angina symptoms had 2-fold greater odds of better quality of life (odds ratio 2.39, 95% confidence interval 1.76 to 3.25) and 5-fold greater odds of better perceived overall health (odds ratio 5.45, 95% confidence interval 3.85 to 7.73). In conclusion, angina frequency is strongly associated with quality of life and physical function in patients with CAD. Even after modeling to adjust for both clinical risk factors and repeated measures within subjects, we found that less frequent angina symptoms were associated with better quality of life.

Rural health disparities in chronic heart disease.

Rural communities suffer from significant disparities in cardiovascular health. The reasons for worse cardiovascular health and outcomes is due to a number of factors including economic, educational, and healthcare access. This commentary draws attention to these challenges and highlights how telemedicine may reduce a portion of this gap. In particular, an opportunity to modify cardiac rehabilitation programs to include a remotely-administered model using telemedicine is a novel method that holds promise.

An online intervention for increasing physical activity in individuals with mood disorders at risk for cardiovascular disease: Design considerations.

BACKGROUND: Physical activity can mitigate the risk of cardiovascular diseases, but the presence of mood disorders makes it challenging to follow or develop a regular exercise habit. We conducted an online comparative effectiveness study (Healthy Hearts Healthy Minds) to evaluate whether an online psychosocial intervention adjunctive to an activity monitor (Fitbit) can improve adherence to physical activity among individuals with mood disorders who have or are at-risk for cardiovascular disease (CVD). METHODS: In this paper, we explore design considerations (including both procedural challenges and achievements) of relevance to our study. RESULTS: Challenges of this study included navigating a complex IRB review process, integrating two study platforms, automating study procedures, and optimizing participant engagement. Achievements of this study included building trust with collaborators, leveraging existing online communities, generating daily data reports, and conducting patient-centered research. LIMITATIONS: These design considerations are based on a single online comparative effectiveness study, and other online intervention studies may be presented with other unique challenges that are specific to their study format or aims. Consistent with some of the generalizability challenges facing other online studies, participants in this study were overall highly educated (most had at least a college degree). CONCLUSIONS: We successfully conducted a large-scale virtual online intervention to increase physical activity of participants with comorbid mood and cardiovascular disorders by overcoming substantial operational and technical challenges. We hope that this exploration of design considerations in the context of our online study can inform upcoming online intervention studies.

Effects of Home-Based Cardiac Rehabilitation on Time to Enrollment and Functional Status in Patients With Ischemic Heart Disease.

Background Cardiac rehabilitation is an established performance measure for adults with ischemic heart disease, but patient participation is remarkably low. Home-based cardiac rehabilitation (HBCR) may be more practical and feasible, but evidence regarding its efficacy is limited. We sought to compare the effects of HBCR versus facility-based cardiac rehabilitation (FBCR) on functional status in patients with ischemic heart disease. Methods and Results This was a pragmatic trial of 237 selected patients with a recent ischemic heart disease event, who enrolled in HBCR or FBCR between August 2015 and September 2017. The primary outcome was 3-month change in distance completed on a 6-minute walk test. Secondary outcomes included rehospitalization as well as patient-reported physical activity, quality of life, and self-efficacy. Characteristics of the 116 patients enrolled in FBCR and 121 enrolled in HBCR were similar, except the mean time from index event to enrollment was shorter for HBCR (25 versus 77 days; P<0.001). As compared with patients undergoing FBCR, those in HBCR achieved greater 3-month gains in 6-minute walk test distance (+95 versus +41 m; P<0.001). After adjusting for demographics, comorbid conditions, and indication, the mean change in 6-minute walk test distance remained significantly greater for patients enrolled in HBCR (+101 versus +40 m; P<0.001). HBCR participants reported greater improvements in quality of life and physical activity but less improvement in exercise self-efficacy. There were no deaths or cardiovascular hospitalizations. Conclusions Patients enrolled in HBCR achieved greater 3-month functional gains than those enrolled in FBCR. Our data suggest that HBCR may safely derive equivalent benefits in exercise capacity and overall program efficacy in selected patients.

Association of Cardiac Rehabilitation With Survival Among US Veterans.

Importance: Participation in cardiac rehabilitation (CR) programs at Veterans Affairs (VA) facilities is low. Most veterans receive CR through purchased care at non-VA programs. However, limited literature exists on the comparison of outcomes between VA and non-VA CR programs. Objective: To compare 1-year mortality and 1-year readmission rates for myocardial infarction or coronary revascularization between VA vs non-VA CR participants. Design, Setting, and Participants: This cohort study included 7320 patients hospitalized for myocardial infarction or coronary revascularization at the VA between 2010 and 2014 who did not die within 30 days of discharge and who participated in 2 or more CR sessions after discharge. The study excluded individuals hospitalized for ischemic heart disease after December 2014 when the VA Choice Act changed referral criteria for non-VA care. Data analysis was performed from November 2019 to January 2020. Exposures: Participation in 2 or more CR sessions within 12 months of discharge at a VA or non-VA facility. Main Outcomes and Measures: The 1-year all-cause mortality and 1-year readmission rates for myocardial infarction or coronary revascularization from date of discharge were compared between VA vs non-VA CR participants using Cox proportional hazards models with inverse probability treatment weighting. Results: The 7320 veterans with ischemic heart disease who participated in CR programs had a mean (SD) age of 65.13 (8.17) years and were predominantly white (6005 patients [82.0%]), non-Hispanic (6642 patients [91.0%]), and male (7191 patients [98.2%]). Among these 7320 veterans, 2921 (39.9%) attended a VA facility, and 4399 (60.1%) attended a non-VA CR facility. Black and Hispanic veterans were more likely to attend CR programs at VA facilities (509 patients [17.4%] and 378 patients [12.9%], respectively), whereas white veterans were more likely to attend CR programs at non-VA facilities (3759 patients [85.5%]). After inverse probability treatment weighting, rates of 1-year mortality were 1.7% among VA CR participants vs 1.3% among non-VA CR participants (hazard ratio, 1.32; 95% CI, 0.90-1.94; P = .15). Rates of readmission for myocardial infarction or revascularization during the 12 months after discharge were 4.9% among VA CR participants vs 4.4% among non-VA CR participants (hazard ratio, 1.06; 95% CI, 0.83-1.35; P = .62). Conclusions and Relevance: These findings suggest that rates of 1-year mortality and 1-year readmission for myocardial infarction or revascularization did not differ for participants in VA vs non-VA cardiac rehabilitation programs. Eligible patients with ischemic heart disease should participate in CR programs regardless of where they are provided.

Patient Perspectives on Declining to Participate in Home-Based Cardiac Rehabilitation: A MIXED-METHODS STUDY.

PURPOSE: A minority of eligible patients participate in cardiac rehabilitation (CR) programs. Availability of home-based CR programs improves participation in CR, yet many continue to decline to enroll. We sought to explore among patients the rationale for declining to participate in CR even when a home-based CR program is available. METHODS: We conducted a mixed-methods evaluation of reasons for declining to participate in CR. Between August 2015 and August 2017, a total of 630 patients were referred for CR evaluation during index hospitalization (San Francisco VA Medical Center). Three hundred three patients (48%) declined to participate in CR. Of these, 171 completed a 14-item survey and 10 patients also provided qualitative data through semistructured phone interviews. RESULTS: The most common reason, identified by 61% of patients on the survey, was "I already know what to do for my heart." Interviews helped clarify reasons for nonparticipation and identified system barriers and personal barriers. These interviews further highlighted that declining to participate in CR was often due to competing life priorities, no memory of the initial CR consultation, and inadequate understanding of CR despite referral. CONCLUSION: We identified that most patients declining to participate in a home-based CR program did not understand the benefits and rationale for CR. This could be related to the timing of the consultation or presentation method. Many patients also indicated that competing life priorities prevented their participation. Modifications in the consultation process and efforts to accommodate personal barriers may improve participation.

Association of Mental Health Conditions With Participation in Cardiac Rehabilitation.

Background Mental health conditions are associated with adverse cardiovascular outcomes in patients with ischemic heart disease, and much of this risk can be attributed to poor health behaviors. Although all patients with ischemic heart disease should be referred for cardiac rehabilitation (CR), whether patients with mental health conditions are willing to participate in CR programs is unknown. We sought to compare CR participation rates among patients with ischemic heart disease with versus without comorbid depression and/or posttraumatic stress disorder (PTSD). Methods and Results We used national electronic health records to identify all patients hospitalized for acute myocardial infarction or coronary revascularization at Veterans Health Administration hospitals between 2010 and 2014. Multivariable logistic regression models were used to determine whether comorbid depression/PTSD was associated with CR participation during the 12 months after hospital discharge. Of the 86 537 patients hospitalized for ischemic heart disease between 2010 and 2014, 24% experienced PTSD and/or depression. Patients with PTSD and/or depression had higher CR participation rates than those without PTSD or depression (11% versus 8%; P<0.001). In comparison to patients without PTSD or depression, the odds of participation was 24% greater in patients with depression alone (odds ratio, 1.24; 95% CI, 1.15-1.34), 38% greater in patients with PTSD alone (odds ratio, 1.38; 95% CI, 1.24-1.54), and 57% greater in patients with both PTSD and depression (odds ratio, 1.57; 95% CI, 1.43-1.74). Conclusions Among patients with ischemic heart disease, the presence of comorbid depression and/or PTSD is associated with greater participation in CR, providing an important opportunity to promote healthy lifestyle behaviors and reduce adverse cardiovascular outcomes among these patients.

Predictors of Patient Participation and Completion of Home-Based Cardiac Rehabilitation in the Veterans Health Administration for Patients With Coronary Heart Disease.

Traditional, facility-based cardiac rehabilitation (CR) is vastly underutilized in the United States. The Veterans Health Administration (VA) has developed new home-based cardiac rehabilitation (HBCR) programs to address this issue. However, the characteristics of patients who choose HBCR are unknown. We sought to determine predictors of participation and completion of HBCR at the San Francisco VA (SFVA). We evaluated patients hospitalized for ischemic heart disease between 2013 and 2016 at SFVA. Logistic regression models were used to identify predictors of participation and completion of HBCR. In 724 patients with ischemic heart disease who were eligible for CR between 2013 and 2016, 314 (43%) enrolled in HBCR. Older age was associated with lower odds of participation in HBCR (odds ratio [OR] 0.84; p <0.01). Additionally, patients with coronary artery bypass grafting (CABG) were twice as likely as those with percutaneous coronary intervention to participate in HBCR (OR 2.03; 95% confidence interval 1.40, 2.97). In HBCR participants, 48% (150/314) completed ≥9 sessions. Patients with CABG were twice as likely as those with percutaneous coronary intervention to complete the HBCR program (OR 2.02; 95% confidence interval 1.18, 3.44). There were no differences in participation or completion rates by gender, race, ethnicity, or rurality. Our study showed that the SFVAMC HCBR program achieved a 43% participation rate, well above the VA average of 13%. There were no disparities by gender, race, or rurality in terms of participation and adherence. CABG as the indication for CR was the most significant predictor of participation and completion of HBCR.

Cardiac Rehabilitation Participation and Mortality After Percutaneous Coronary Intervention: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program.

Background Cardiac rehabilitation (CR) is strongly recommended after percutaneous coronary intervention (PCI), but it is underused. We sought to evaluate CR participation variation after PCI and its association with mortality among veterans. Methods and Results Patients undergoing PCI between 2007 and 2011 were identified in the Veterans Affairs Clinical Assessment, Reporting, and Tracking database and followed up until January 25, 2017. We excluded patients who died within 30 days of PCI and calculated the percentage participating in ≥1 outpatient CR visits within 12 months after PCI. We constructed multivariable hierarchical logistic regression models for CR participation, clustered by facility. We estimated propensity scores for CR participation, matched participants and nonparticipants by propensity score, calculated mortality rates, and estimated the association with mortality using Cox proportional hazards models. Participation in CR after PCI was 6.9% (2986/43 319) and varied significantly by PCI facility (range, 0%-36%). After 6.1 years median follow-up, CR participants had a 33% lower mortality rate than all nonparticipants (3.8 versus 5.7 deaths/100 person-years; hazard ratio, 0.67; 95% confidence interval, 0.61-0.75; P<0.001) and a 26% lower mortality rate than 2986 propensity-matched nonparticipants (3.8 versus 5.1 deaths/100 person-years; hazard ratio, 0.74; 95% confidence interval, 0.65-0.84; P<0.001). Participants attending ≥36 sessions had the lowest mortality rate (2.4 deaths/100 person-years; hazard ratio, 0.47; 95% confidence interval, 0.36-0.60; P<0.001). Conclusions CR participation after PCI among veterans is low overall, with significant facility-level variation. CR participation is associated with lower mortality rates in veterans. Additional efforts are needed to promote CR participation after PCI among veterans.

Participation in Pulmonary Rehabilitation by Veterans Health Administration and Medicare Beneficiaries After Hospitalization for Chronic Obstructive Pulmonary Disease.

BACKGROUND: Hospitalization with acute exacerbation of chronic obstructive pulmonary disease (COPD) is common and costly to the health care system. Pulmonary rehabilitation (PR) can improve symptom burden and morbidity associated with COPD. The use of PR among Medicare beneficiaries is poor, and the use by Veterans Health Administration (VHA) beneficiaries is unknown. We sought to determine whether participation in PR was similarly poor among eligible veterans compared with Medicare beneficiaries. METHODS: We performed a retrospective study using national VHA and Medicare data to determine the proportion of eligible patients who participated in PR after hospitalization for an acute exacerbation of COPD between January 2007 and December 2011. We also evaluated patient characteristics including demographic factors and comorbid medical history associated with participation. RESULTS: Over the 5-year study period, 485 (1.5%) of 32 856 VHA and 3199 (2.0%) of 158 137 Medicare beneficiaries hospitalized for COPD attended at least 1 session of PR. Among both VHA and Medicare beneficiaries, participation was higher in those who had had comorbid pneumonia or pulmonary hypertension and was lower in older patients. Although participation increased in both groups over time, it remained exceedingly low overall. CONCLUSION: Pulmonary rehabilitation is significantly underused in both the VHA and Medicare populations. Although comorbid pulmonary disease is associated with higher use, the proportion of eligible patients who participate remains extremely low.

Geographic Variation in Cardiac Rehabilitation Participation in Medicare and Veterans Affairs Populations: Opportunity for Improvement.

BACKGROUND: Cardiac rehabilitation is strongly recommended after myocardial infarction, percutaneous coronary intervention, or coronary artery bypass surgery, but it is historically underused. We sought to evaluate variation in cardiac rehabilitation participation across the United States. METHODS: From administrative data from the Veterans Affairs (VA) healthcare system and a 5% Medicare sample, we used International Classification of Diseases, 9th Revision codes to identify patients hospitalized for myocardial infarction, percutaneous coronary intervention, or coronary artery bypass surgery from 2007 to 2011. After excluding patients who died in ≤30 days of hospitalization, we calculated the percentage of patients who participated in ≥1 outpatient visits for cardiac rehabilitation during the 12 months after hospitalization. We estimated adjusted and standardized rates of participation in cardiac rehabilitation by state using hierarchical logistic regression models. RESULTS: Overall, participation in cardiac rehabilitation was 16.3% (23 403/143 756) in Medicare and 10.3% (9123/88 826) in VA. However, participation rates varied widely across states, ranging from 3.2% to 41.8% in Medicare and 1.2% to 47.6% in VA. Similar regional variation was observed in both populations. Patients in the West North Central region (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota) had the highest participation, whereas those in the Pacific region (Alaska, California, Hawaii, Oregon, and Washington) had the lowest participation in both Medicare (33.7% versus 10.6%) and VA (16.6% versus 5.1%) populations. Significant hospital-level variation was also present, with participation ranging from 3% to 75% in Medicare and 1% to 43% in VA. CONCLUSIONS: Cardiac rehabilitation participation remains low overall in both Medicare and VA populations. However, remarkably similar regional variation exists, with some regions and hospitals achieving high rates of participation in both populations. This provides an opportunity to identify best practices from higher performing hospitals and regions that could be used to improve cardiac rehabilitation participation in lower performing hospitals and regions.

Participation in Cardiac Rehabilitation Among Patients With Heart Failure.

BACKGROUND: Cardiac rehabilitation (CR) is linked to reduced mortality and morbidity, including improvements in cardiorespiratory fitness, psychosocial state, and quality of life in patients with heart failure (HF). However, little is known about CR utilization among patients with HF. OBJECTIVE: We sought to determine (a) the proportion of patients with HF who participated in CR and (b) patient characteristics associated with participation. METHODS: A retrospective study was conducted with the use of national data from the Centers for Medicare and Medicaid Services and the Veterans Health Administration. We used primary discharge ICD-9 codes to identify patients hospitalized for HF during 2007-2011 and identified CR participation with the use of current procedure terminology codes from claims data. Multivariate logistic regression was used to identify patient characteristics associated with CR participation. RESULTS: There were 66,710 veterans and 243,208 Medicare beneficiaries hospitalized for HF and 1554 (2.3%) and 6280 (2.6%), respectively, who attended ≥1 sessions of outpatient CR. Among Medicare beneficiaries, men were more likely than women to participate in CR (3.7% vs 1.8%; P < .001), but there was no gender difference among veterans (2.3% vs 2.8%; P = .40). Characteristics associated with participation in CR in both groups included younger age, white race, and history of ischemic heart disease. CONCLUSIONS: Very few HF patients participated in CR, with lower rates among older non-white women with a history of depression or other chronic medical conditions. Because Medicare has recently introduced coverage for CR in patients with systolic HF, we must increase efforts to improve CR participation, especially among these vulnerable groups.

The Design and Implementation of a Home-Based Cardiac Rehabilitation Program.

A home-based cardiac rehabilitation program improves access and enrollment by using an evidence-based alternative model of care.
