Li Y, et al. - Whether CHADS₂ and R₂CHADS₂ scores could predict long-term outcome for patients with coronary artery disease (CAD) was investigated. A median 2.9-year follow-up was carried out to track the incidence of composite end point consisting of cardiovascular (CV) death, myocardial infarction (MI), stroke, heart failure, and all-cause death. CHADS₂ and R₂CHADS₂ scores were found to be quick and useful as tools to predict long-term outcome for patients with CAD. R₂CHADS₂ score vs CHADS₂ score had better discrimination for the prediction of long-term combined outcome, as demonstrated in receiver-operating characteristic analysis.
