Abstract 4142395: Lipid Trends of Adults Who Participate in Hybrid Cardiac Rehabilitation

Background: Hybrid cardiac rehabilitation (HCR) is an emerging approach to increase participation in cardiac rehabilitation, which targets improvements in functional status and broader risk factor modification including lipid management. However, long-term lipid control trends of patients engaging in HCR remain unexplored. Methods: Using data from a quality improvement program initiated during COVID-19, we conducted a retrospective analysis of 68 adults eligible for HCR from Jan 2021 to Feb 2023 at the Johns Hopkins Health System (Baltimore, MD), utilizing the Corrie digital health platform. This multi-component platform combines expert knowledge with gamified education and virtual coaching to deliver HCR. Patients hospitalized for cardiovascular events qualifying for HCR were recruited for a pilot study of a randomized controlled trial (mTECH REHAB; NCT05238103). We modeled trends in low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides via mixed-effects regression. Results: Among 68 eligible adults, 41 participated in HCR, with a mean age of 60.1 years, 78.1% male, 24.3% Black, and 14.6% Asian/Mixed. HCR participation was significantly associated with being married (61% vs 33%, p=0.044) or employed (63% vs 26%, p=0.015). On average, 2.3 lipid panels were assessed per person over a median of 12 months (max 30 months) post-discharge. During this period, LDL-C levels decreased from 84.6 mg/dL (95% CI: 75.0-94.1) to 53.0 mg/dL (95% CI: 34.3-71.8) (p for trend = 0.003). Non-HDL-C decreased from 105.9 mg/dL (95% CI: 95.7-116.1) to 74.2 mg/dL (95% CI: 54.1-94.3) (p for trend = 0.005). Levels of HDL-C and triglycerides showed no significant changes (p for trend = 0.724 and 0.607). Among 34 participants with ≥2 lipid panels, the proportion of LDL-C <70 mg/dL increased from 41.2% at hospitalization to 64.7% at the most recent check, and LDL-C <55 mg/dL increased from 14.7% to 38.2%. Conclusion: Improvements in atherogenic lipid levels, in particular LDL-C and non-HDL-C, were observed in adults participating in HCR after a cardiovascular event. Our findings highlight the potential of HCR to support optimal lipid management in adults with cardiovascular disease.
