Abstract

Introduction: Cardiac rehabilitation (CR) is an evidence-based secondary prevention strategy that improves functional capacity, quality of life, and cardiovascular outcomes. However, adherence to CR programs remains suboptimal, limiting their effectiveness. Methods: A retrospective multicenter cohort study was conducted among patients enrolled in outpatient CR programs at two specialized cardiovascular centers. Adherence was defined as attendance at ≥70% of the prescribed sessions (≥25 of 36 sessions). Bivariate analyses were performed to compare adherent and non-adherent participants. Variables with p < 0.20 were included in a multivariable logistic regression model to identify factors independently associated with adherence. Results: A total of 210 participants were included, of whom 77.6% (163/210) were classified as adherent. The median age was 68 years (IQR 60.3-75.0), and 64.3% were men. Most participants (70.5%) completed more than 30 rehabilitation sessions. Adherence rates were highest among patients undergoing surgical myocardial revascularization (80.6%) and valve surgery (76.0%). In multivariable analysis, program duration was the only factor significantly associated with adherence (OR = 4.59; 95% CI: 2.46-8.59; p < 0.001). History of dyslipidemia showed a non-significant trend toward higher adherence (OR = 3.29; 95% CI: 0.91-11.90; p = 0.069). Educational level, left ventricular ejection fraction, and health insurance affiliation were not independently associated with adherence. Conclusions: Adherence to CR was high in this cohort. Longer participation in the program was the only independent predictor of adherence, highlighting the importance of strategies that promote sustained engagement throughout the rehabilitation process.
