ObjectiveTo validate of the Chinese system for cardiac operative risk evaluation(SinoSCORE)in Cantonese surgery patients.MethodsData from Guangdong Cardiovascular Institute in the period January 2004 through December 2008 were analyzed on 2462 Cantonese heart surgery patients.First，compared risk factors of this series and database of SinoSCORE，and then calculated the additive score of each patients and evaluate the discrimination and calibration of sinoSCORE in Cantonese patients.ResultsThere were some differences between the risk factors of patients from two groups.The gender，smoking，diabetes，hyperlipemia，hypertension，chronic pulmonary diseases，stroke，cardiovascular surgery history，left main disease，atrial fibrillation/atrial flutter，pulmonary arterial hypertension，concomitant coronary surgery and concomitant valve surgery in Cantonese patients were different between two groups.However，The SinoSCORE was able to predict the in-hospital mortality of senior patients with good discrimination(Hosmer-Lemeshow test，P=0.34)and calibration(the area under the receiver operating characteristic curve，0.84，P ＜ 0.01).ConclusionSinoSCORE was able to predict the in-hospital mortality of Cantonese heart surgery patients.14 refs，1 fig，2 tabs.
