Area Deprivation Index and Cardiovascular Events: CAN CARDIAC REHABILITATION MITIGATE THE EFFECTS?

Introduction: Neighborhood socioeconomic status is associated with health outcomes. Cardiac rehabilitation (CR) provides a cost-effective, multidisciplinary approach to improve outcomes in cardiovascular disease. We aimed to evaluate the association of the Area Deprivation Index (ADI), a marker of neighborhood social composition, with risk of recurrent cardiovascular outcomes and assessed the modifying effect of CR. Methods: We identified patients with a primary diagnosis of (1) myocardial infarction or (2) incident heart failure (HF) admitted to a large-sized regional health center during 2010-2018. We derived the ADI from home addresses and categorized it into quartiles (higher quartiles indicating increased deprivation). We obtained number of CR visits and covariates from the health record. We compared rehospitalization (cardiovascular, acute coronary syndrome [ACS], and HF) and mortality rates across ADI quartiles. Results: We included 6957 patients (age 69.2 ± 13.4 yr, 38% women, 89% White race). After covariate adjustment, the ADI was significantly associated with higher incidence rates (IRs)/100 person-yr of cardiovascular rehospitalization (quartile 1, IR 34.6 [95% CI, 31.2-38.2]; quartile 4, 41.5 [95% CI, 39.1-44.1], P
