Abstract:
ObjectiveTo assess the prognostic efficiency of three different risk socres in patients underwent redo-coronary artery bypass grafting (redo-CABG).MethodsFrom January 1997 to July 2011,57 patients underwent redo-CABG in Fu Wai Hospital.All patients were prospectively scored for operative mortality using EuroScore,STS Score and Sinoscore.The overall expected mortality were compared with the observed mortality.Discrimination was evaluated by receiver operating characteristic (ROC) cures and area under a ROC curve (AUC).ResultsFour patients died in the whole group,the observed mortality was 7％.The overall predicted mortality of EuroScore,STS Score and SinoScore were 5.6％,2.2％ and 1.5％,all lower than the observed mortality.The AUC of the three kinds of score were respectively 0.495,0.557 and 0.535,which indicated that the discrimination of the three kinds of score are poor.ConclusionThe predictive value of EuroScore,STS Score and SinoScore for early postoperative mortality in patients undergoing redo-CABG is poor.Surgical technology is an important predictor for early postoperative mortality.
