Abstrakt:	Introduction: Determining operative mortality risk is mandatory for adult cardiac surgery. Patients should be informed about the operative risk before surgery. There are some risk scoring systems that compare and standardize the results of the operations. These scoring systems needed to be updated recently, which resulted in the development of EuroSCORE II. In this study, we aimed to validate EuroSCORE II by comparing it with the original EuroSCORE risk scoring system in a group of high-risk octogenarian patients who underwent coronary artery bypass grafting (CABG). Material and Methods: The present study included only high-risk octogenarian patients who underwent isolated coronary artery bypass grafting in our center between January 2000 and January 2010. Redo procedures and concomitant procedures were excluded. We compared observed mortality with expected mortality predicted by EuroSCORE (logistic) and EuroSCORE II scoring systems. Results: We considered 105 CABG operations performed in octogenarian patients between January 2000 and January 2010. The mean age of the patients was 81.43 ± 2.21 years (80-89 years). Thirty-nine (37.1%) of them were female. The two scales showed good discriminative capacity in the global patient sample, with the AUC (area under the curve) being higher for EuroSCORE II (AUC 0.772, 95% CI: 0.673-0.872). The goodness of fit was good for both scales. Conclusions: We conclude that EuroSCORE II has better AUC (area under the ROC curve) compared to the original EuroSCORE, but both scales showed good discriminative capacity and goodness of fit in octogenarian patients undergoing isolated coronary artery bypass grafting.
