Abstract
BACKGROUND: Coronary Artery Bypass Graft (CABG) is one solution to overcome cardiovascular problems. EuroSCORE II is a scoring system to predict mortality risk in patients undergoing cardiac surgery including CABG. Unfortunately, there's still much debate about the benefits of EuroSCORE II in Asia, including Indonesia. This study aims to validates EuroSCORE II in predicting the outcomes in patients underwent CABG without any other procedure. RESULTS: A total of 2628 patients were included. The mean age was 59 years, mostly male (84.97%; n = 2233). Most patients underwent elective surgery (93.07%; n = 2446) and only 1.67% (n = 44) of the patients has high EuroSCORE category. Death was found in 4.22% (n-111) patients. EuroSCORE II had fair discriminant power (AUC 0.72), but a lower mortality predicted value for each group. CONCLUSION: The parameters in EuroSCORE II are related with mortality in isolated CABG patients, but they cannot be used as mortality predictors in Indonesia.
