Background: Non-ST-elevation myocardial infarction (NSTEMI) carries a poor prognosis, and accurately prognostication has significant clinical importance. In this study, we analyzed the predictive value of the CHADS2, CHA2DS2-VASc, and R2-CHADS2scores for major adverse cardiac events (MACE) following percutaneous coronary intervention (PCI) in patients with NSTEMI using data from a prospective multicenter registry.Methods and Results: The registry included 440 consecutive patients with NSTEMI and coronary artery disease who underwent successful PCI. Patients were clinically followed for up to 3 years or until the occurrence of MACE. MACE was defined as a composite of all-cause death and nonfatal MI. During the follow-up period, 55 patients (12.5%) experienced MACE. Risk analysis of MACE occurrence, adjusted for the multivariable model, demonstrated a significant increase in risk with higher CHADS2, CHA2DS2-VASc, and R2-CHADS2scores. Kaplan-Meier analysis showed a higher incidence of MACE in patients with higher CHADS2, CHA2DS2-VASc, and R2-CHADS2scores, both in the short- and long-term periods.Conclusions: Patients with NSTEMI and higher CHADS2, CHA2DS2-VASc, and R2-CHADS2scores displayed a greater incidence of MACE.
