欧洲心脏手术风险评估系统预测中国人心瓣膜手术后并发症的发生及预后

目的评估欧洲心脏手术风险评估系统(EuroSCORE)能否有效预测中国人心瓣膜手术后重症监护(ICU)时间延长、死亡以及主要并发症的发生。方法将2004年1月至2006年1月北京阜外心血管病医院连续收治的后天性心瓣膜病患者2 218例纳入研究,其中男1 047例,女1 171例;年龄49.26±11.10岁。所有患者均行心瓣膜手术。将EuroSCORE的logistic模型和additive模型应用于所有患者,评估两种方法预测心瓣膜手术后患者死亡I、CU时间延长以及重要并发症的发生。模型的区分能力采用受试者工作特征曲线(ROC曲线)评价,校正能力采用Hosmer-Lemeshow拟合优度检验评价。结果 EuroSCORE的logistic模型和additive模型预测术后死亡的ROC曲线面积分别为0.710和0.690,ICU时间延长为0.670和0.660,心力衰竭为0.650和0.640,呼吸功能衰竭为0.720和0.710,肾功能衰竭为0.700和0.740,二次开胸止血为0.540和0.550;其中肾功能衰竭和心力衰竭两种模型的ROC曲线下面积差异有统计学意义(P0.05)。EuroSCORE预测术后死亡、心力衰竭、肾功能衰竭、二次开胸止血以及ICU时间延长的Hosmer-Lemeshow拟合优度欠佳,但logistic模型预测术后呼吸功能衰竭的拟合优度良好(P=0.120)。结论 EuroSCORE预测中国人心瓣膜手术后死亡I、CU时间延长以及重要并发症发生的预测效果较差,但logistic模型可用来预测术后呼吸功能衰竭。

European System for Cardiac Operative Risk Evaluation Predicts Postoperative Complications and Prognosis of Chinese Patients Operated for Acquired Heart Valve Diseases

Objective To evaluate the prediction validation of European system for cardiac operative risk evaluation(EuroSCORE) in prolonged intensive care unit(ICU) stay,mortality,and major postoperative complications for Chinese patients operated for acquired heart valve disease.Methods Between January 2004 and January 2006,2 218 consecutive patients treated for acquired heart valve diseases were enrolled in Fu Wai Hospital.All these patients accepted valvular surgery.Both logistic model and additive model were appli...
