title: [Role of EuroSCORE and SinoSCORE in prediction of early postoperative quality of life in patients after coronary artery bypass surgery].
abstract: OBJECTIVE
  To investigate the predicting value of European system for cardiac operative risk evaluation (EuroSCORE) and sino system for coronary operative risk evaluation (SinoSCORE) in early quality of life of patients after coronary artery bypass surgery (CABG).
  
  
  METHODS
  A total of 218 consecutive patients who underwent CABG from March 2010 to January 2013 were evaluated with both systems before operation. Health related quality of life (QoL) was estimated by using 36-item short form health survey (SF-36) preoperatively and postoperatively in order to evaluate the predicting value of the two systems in early post-operative QoL. Calibration was evaluated by Hosmer-l,emeshow goodness-of-fit test.Discrimination was tested by determining the area under the receiver operating characteristic (ROC) curve.
  
  
  RESULTS
  There was no significant difference between the accumulation of the EuroSCORE and SinoSCORE in the all patients (t=-0.904, P=0.368), When using Wilcoxon test on life quality in the preoperative and postoperative patients respectively,the data showed that the quality of life improved significantly in various dimensions of the postoperative patients (Z=-2.886, P<0.001).Except for bodily pain (BP) and mental health (MH), statistically significant correlation was found between the preoperative risk evaluation scores and the postoperative QoL scores (r:-0.203 to -0.493, P<0.05). Logistic regression analyses indicated that both the scores emerged as the independent predictor for a relatively worse QoL (OR>1, P<0.05). Furthermore, the EuroSCORE predicted the outcome with a higher OR. For SinoSCORE the Hosmer-Lemeshow test was significant (P=0.628) and the area under ROC curve was 0.754.For the EuroSCORE the Hosmer-Lemeshow test was significant (P=0.538) and the area under ROC curve was 0.854.
  
  
  CONCLUSIONS
  Both EuroSCORE and SinoSCORE could be viewed as a predictor for several aspects of postoperative QoL, while EuroSCORE might have a greater predicting value.
