However, the impact of cognitive impairment (CI) on these secondary prevention strategies following ACS has not been examined. Methods: Cognitive status of 1374 patients with ACS from six hospitals in Massachusetts and Georgia enrolled in the ongoing TRACE-CORE (Transitions, Risks, and Actions in Coronary EventsCenter for Outcomes Research and Education) study was assessed during hospitalization using the 41-point Telephone Interview for Cognitive Status (TICS). Information on recommendation and initiation of changes to diet, exercise, tobacco and alcohol use, stress, and cardiac rehabilitation attendance was collected through self-report one month after discharge. Medication adherence was assessed using the 8-item Morisky Scale. Among patients who reported receiving a recommendation for a lifestyle change, we modeled associations between CI and initiation of lifestyle changes and medication adherence, adjusting for demographics via logistic regression. Results: Mean age of participants was 63.0±11.1 years, 67% were male and 79% white; 526 (38.3%) screened positive for CI (TICS score ≤30) during hospitalization. Screening positive for CI was associated with being older, male, non-white, and less educated. Patients with CI more frequently received a recommendation to reduce alcohol use (25% vs. 16% of drinkers, p=.003) but were referred less often to a cardiac rehabilitation program (45% vs. 61%, p=.01). Among patients referred to cardiac rehabilitation (n=743), those with CI at baseline were less likely to report rehabilitation attendance at 1-month (OR= 0.70, 95%CI 0.50-0.97) compared to patients with normal cognitive function. Initiation of other lifestyle changes and medication adherence did not differ by cognitive status. Conclusions: CI is common among patients hospitalized for ACS and is associated with recommendation and initiation of certain lifestyle changes, making it an important factor to consider during the peri-discharge period.
