Duration of Heightened Risk of Acute Ischemic Stroke After Hospitalization for Acute Systolic Heart Failure.

ABSTRACT: Background The duration and magnitude of increased stroke risk after a hospitalization for acute systolic heart failure (HF) remains uncertain. Methods and Results The authors performed a retrospective cohort study using claims (2008-2018) from a nationally representative 5% sample of Medicare beneficiaries aged ≥66 years. Cox regression models were fitted separately for the groups with and without acute systolic HF to examine its association with the incidence of ischemic stroke after adjustment for demographics, stroke risk factors, and Charlson comorbidities. Corresponding survival probabilities were used to compute the hazard ratio (HR) in each 30-day interval after discharge. The authors stratified patients by the presence of atrial fibrillation (AF) before or during the hospitalizati
