Short Sleep Duration After Hospital Evaluation for Acute Coronary Syndrome Is Associated With Increased Risk of 6-Month Readmission.

Abstract：

OBJECTIVE:Hospital readmission after acute coronary syndrome (ACS) is associated with worsened patient outcomes and financial burden. Short sleep duration is a risk factor for cardiovascular events and may therefore represent a behavioral factor that increases risk of adverse posthospitalization outcomes. This study examined whether short sleep duration in the month after hospital evaluation for ACS is associated with 6-month all-cause emergency department (ED) and hospital readmission. METHODS:The current analyses entail a secondary analysis of a larger prospective observational cohort study. Sleep duration during the month after hospital evaluation for ACS was assessed subjectively and dichotomized as short (<6 hours) or not short (≥6 hours). A Cox proportional hazards model was used to assess the association between short sleep duration during the month after ACS hospital evaluation and 6-month all-cause ED/hospital readmission. RESULTS:A total of 576 participants with complete data were included in analyses. Approximately 34% of participants reported short sleep duration during the month after ACS evaluation. Short sleep duration was significantly associated with 6-month all-cause ED/hospital readmission (hazard ratio = 2.03; 95% confidence interval = 1.12-3.66) in the model adjusted for age, sex, race/ethnicity, clinical severity, cardiac and renal markers, depression, acute stress, and including a sleep duration by ACS status interaction. CONCLUSIONS:Short sleep duration after ACS hospital evaluation is prevalent and is associated with increased risk of all-cause readmission within 6 months of discharge. Current findings suggest that short sleep duration is an important modifiable behavioral factor to consider after hospital evaluation for ACS.
