Background Cardiac rehabilitation (CR) is a comprehensive secondary cardiovascular disease program with structured lifestyle interventions to reduce morbidity and mortality. The American Heart Association cardiovascular health (CVH) framework measures health‐promoting behaviors and clinical factors, but it has not been rigorously evaluated in the CR setting. Methods This retrospective cohort study analyzed patients attending CR from January 2018 to September 2020. Patients were evaluated at baseline (pre‐CR) and completion (post‐CR) using 3 clinical factors (blood pressure, cholesterol, and hemoglobin A1c) and 4 health behaviors (smoking, body mass index, physical activity, and diet). CVH score was computed as a composite of each Life's Simple 7 component by assigning 0 points for poor, 1 point for intermediate, or 2 points for ideal (range 0–14 points). CVH scores were further categorized as poor (0–6 points), intermediate (7–8 points), and ideal (9–14 points). Missing data in the analysis were accounted for using a multiple imputation procedure. Results Patients (N=937) were aged 64.0±13.4 years old, 34% women, and attended 11±12 CR sessions. Pre‐CR, 97.2% had poor CVH scores, 2.8% had intermediate scores, and none met ideal CVH criteria. Post‐CR, there was a reduction in poor scores across all metrics except for hemoglobin A1c, which increased (40.6%–43.5%). Younger patients showed improvement in hemoglobin A1c, while older patients improved in body mass index and blood pressure. Conclusions Our study demonstrates the efficacy of CR in improving CVH but underscores the need for better blood glucose management. Tailored interventions based on age and sex may further optimize outcomes for CR participants.

Background: Cardiac rehabilitation (CR) is essential to secondary cardiovascular disease prevention and management of cardiac patients. Despite its proven benefits, CR remains underutilized with enrollment and completion rates ranging from 10-30% in the US. Yet, there is a scarcity of nationally representative data among diverse populations on socioeconomic differences in barriers and beliefs of CR participation and delivery mode preferences. Hypothesis: The perceptions (barriers, beliefs), CR delivery mode preferences, and CR utilization (prior enrollment) varies by socioeconomic status (SES) among CR-eligible individuals. Methods: We conducted an anonymous national electronic survey from March 2023 to January 2024 of individuals self-reporting a prior CR-eligible diagnosis. The 22-item CR Barriers Scale assessed perceived barriers to CR enrollment and participation using a 5-point Likert scale (strongly disagree to strongly agree). A 13-item, validated questionnaire assessed 4 subscales pertaining to patients’ beliefs about CR, each rated on a 5-point Likert scale (strongly disagree to strongly agree): perceived necessity, concerns about exercise, practical barriers and perceived suitability. CR delivery mode preferences were ascertained (eg, virtual, at-home, etc.). Mean barriers and belief scores as well as delivery mode preferences were stratified by SES. Low SES was defined as ≤ high school education, Medicaid insurance, or uninsured. High SES was defined as > high school education and non-Medicaid health insurance. Responses were analyzed using descriptive statistics with R software. Results: A total of 466 participants completed the survey (38.1% women, 30.6% minoritized racial/ethnic group, 29.6% low SES, 95% response rate) ( Table 1 ). The majority indicated prior enrollment in CR (81.5%) with no difference by SES. CR barrier scores did not differ significantly by SES (p=0.331) ( Table 2 ). Beliefs about CR perceived necessity and perceived suitability differed by SES (p<0.001 and p=0.025), but beliefs regarding concerns about exercise and practical barriers did not. The low SES group reported a higher preference for completely at-home CR compared to the high SES group (33.6% vs 7.4%, p<0.001). Conclusion: Our findings suggest that CR beliefs varied by SES while utilization did not. For CR-eligible patients experiencing socioeconomic disadvantage, at-home CR may be a preferred alternative to center-based CR to increase CR participation and adherence.

Background: Life's Simple 7 (LS7) have been identified as key health factors aimed at achieving ideal cardiovascular health (CVH) and improving healthy life expectancy; however, it is unclear if different patient populations respond similarly to optimization of health behaviors. We sought to quantify the contribution of sex and age differences to changes in LS7 components in patients participating in cardiac rehabilitation. Methods: We included 937 adult patients who participated in CR from January 2018 to September 2020. LS7 metrics at baseline (pre-CR) and completion of CR (post-CR) were collected and changes in LS7 components (body mass index (BMI), diet, smoking, physical activity (PA), blood pressure (PB), cholesterol, glucose) were assessed by sex and age groups (<65 vs ≥65 years old). Each LS7 component was assigned 0 (poor), 1 (intermediate), or 2 (ideal) points and a final score was computed to estimate an individual’s level of CVH (0-14 pts): 0-6 = poor, 7-8= intermediate, 9 -14= ideal. Results: The mean age was 64±13 years, and 34% were female. Patients attended a mean of 11.1±12.5 CR sessions. LS7 components with the highest proportion within the poor category were HbA1c (41%) and BMI (50%) at the time of CR enrollment; neither women nor men showed improvement on either component. The trend towards improvement from poor to intermediate range on cholesterol and BP metrics was seen only in older patients (Table 1). Mean LS7 score improvement was greater in the older group, P=.01 (Fig 1). Both women and men equally improved LS7 scores (Table 2, Fig 2). Conclusions: Patients participating in CR demonstrated improvement in overall LS7 scores regardless of sex and age. However, age disparities exist in LS7 metrics, with exacerbated differences noted by a lack of improvement in LS7 components such as BP and cholesterol in younger patients. Our insights provide opportunities to explore equitable CVH.

Background Innovative restructuring of cardiac rehabilitation (CR) delivery remains critical to reduce barriers and improve access to diverse populations. Destination Cardiac Rehab is a novel virtual world technology‐based CR program delivered through the virtual world platform, Second Life, which previously demonstrated high acceptability as an extension of traditional center‐based CR. This study aims to evaluate efficacy and adherence of the virtual world–based CR program compared with center‐based CR within a community‐informed, implementation science framework. Methods Using a noninferiority, hybrid type 1 effectiveness‐implementation, randomized controlled trial, 150 patients with an eligible cardiovascular event will be recruited from 6 geographically diverse CR centers across the United States. Participants will be randomized 1:1 to either the 12‐week Destination Cardiac Rehab or the center‐based CR control groups. The primary efficacy outcome is a composite cardiovascular health score based on the American Heart Association Life's Essential 8 at 3 and 6 months. Adherence outcomes include CR session attendance and participation in exercise sessions. A diverse patient/caregiver/stakeholder advisory board was assembled to guide recruitment, implementation, and dissemination plans and to contextualize study findings. The institutional review board–approved randomized controlled trial will enroll and randomize patients to the intervention (or control group) in 3 consecutive waves/year over 3 years. The results will be published at data collection and analyses completion. Conclusions The Destination Cardiac Rehab randomized controlled trial tests an innovative and potentially scalable model to enhance CR participation and advance health equity. Our findings will inform the use of effective virtual CR programs to expand equitable access to diverse patient populations.

Introduction: Cardiac rehabilitation (CR) is a comprehensive secondary cardiovascular disease (CVD) program which integrates structured lifestyle interventions to reduce morbidity and mortality. The Life’s Simple 7 (LS7) is an objective measure of cardiovascular health (CVH) which incorporates health-promoting behaviors and clinical factors however, it has not been rigorously evaluated in the CR setting. Methods: Retrospective cohort study of 937 patients who attended center-based CR at Mayo Clinic from Jan 2018 -Sept 2020. Patient characteristics and LS7 component metrics at baseline (pre-CR) and completion (post-CR) were collected: 3 clinical factors (blood pressure [BP], cholesterol, and hemoglobin A1c [HbA1c]), and 4 health behaviors (smoking, body mass index [BMI], physical activity [PA] and diet). LS7 score was computed as a composite of each LS7 component by assigning 2-points for ideal, 1-point for intermediate, or 0-points for poor CVH ranging from 0-14 points. LS7 score was further categorized as poor 0-6, intermediate 7-8 and ideal 9 -14. Results: Patients were 64±13 years old, 34% were female, and attended a mean of 11±12 CR sessions, Table 1. At baseline, the LS7 components with the highest proportion within the poor category were HbA1c (201/495, 41%) and BMI (465/936, 50%), Table 2. From pre to post-CR, there was a reduction in proportion of patients classified within the poor category for each LS7 component except HbA1c ( Figure 1 ), and the proportion of patients with LS7 scores in the ideal range increased from 6.4% to 19% (P<0.001). There was a statistically significant improvement in LS7 score from 5.5±1.8 to 6.7± 2.4 (+Δ1.6±2.4, P<.0001), Table 2 . Conclusions: Patients attending CR demonstrated an improvement in LS7 score and almost all LS7 components suggesting an overall positive impact of CR on CVH. Further research is needed to better understand the impact of the individual LS7 components on CV outcomes in diverse populations participating in CR.
