Abstract: Background: Acute coronary syndrome (ACS) patients have a wide spectrum of risks for subsequent cardiovascular events and death. However, there is no simple, convenience scoring system to identify risk of adverse outcomes. We investigated whether CHADS2 and CHA2DS2-VASc scores were useful tools to assess the risk for adverse events among ACS patients. Methods: This observational prospective study was conducted at 39 hospitals. Totally 3,183 patients with ACS were enrolled, and CHADS2 and CHA2DS2-VASc scores were calculated. The primary endpoint was occurrence of adverse event, including subsequent myocardial infarction, stroke, or death, within 1 year of discharge. Results: CHADS2 and CHA2DS2-VASc scores were significant predictors of adverse events in separate multivariate regression analyses. A Kaplan-Meier analysis of CHADS2 and CHA2DS2-VASc scores of ≥2 showed a higher rate of adverse events as compared with scores of
