Objective:To assess the clinical value of EuroSCORE for predicting the early prognosis in patients with coronary artery bypass grafting(CABG)in China.Methods:We retrospectively summarized the data of 1623 patients who underwent CABG or combined with CABG surgery from June 2006 to December 2007 in our hospital.The EuroSCORE additive model and multiple regression model were performed to assess the postoperative mortality,the extended ICU time and the major important complications.The resolution ability was eva-luated by the receiver operating characteristic(ROC)curve and the calibration evaluation was conducted by Hosmer-Lemeshow X2 test.Results:The additive model and the logistic model of EuroSCORE predicted that the postoperative mortality area under ROC curves were 0.787 and 0.801 respectively,the extended ICU time were 0.725 and 0.741,the postoperative respiratory failure were 0.692 and 0.702,the postoperative kidney failure were 0.788 and 0.796,the second open thoracic surgery for bleeding were 0.711 and 0.723 respectively.Hosmer-Lemeshow X2 test presented that the additive model had the better fit than the logistic model.Conclusion:Our work indicated that the clinical value of EuroSCORE was at the middle level in Chinese patients for predi-cting the CABG mortality,the extended ICU time,the postoperative renal failure and the second open thoracic surgery for blee-ding.The additive model had the better prediction accuracy than the logistic model.
