Validation of the Chinese system for cardiac operative risk evaluation (SinoSCORE) in senior heart surgery patients / 中华胸心血管外科杂志

ABSTRACT

Objective To validate of the Chinese system for cardiac operative risk evaluation (SinoSCORE) in senior heart surgery patients. Methods Data from 43 Chinese Medical Centers in the period January 2004 through December 2008 were analyzed on 9445 heart surgery patients aged over 65 years. Firstly, risk factors of this series and database of SinoSCORE were compared. Then, the additive score of each patients and the discrimination and calibration of sinoSCORE in elder patients were calculated. Results There were significant differences between the risk factors of patients from two groups. Howerever,the SinoSCORE was able to predict the in-hospital mortality of senior patients with good discrimination ( Hosmer-Lemeshow test,P =0.45 ) and calibration (the area under the receiver operating characteristic curve, 0.73, P ＜ 0.01 ). Conclusion SinoSCORE was able to predict the in-hospital mortality of senior heart surgery patients.
