KAMIR评分与GRACE评分预测急性心肌梗死患者一年死亡率的临床研究

摘要

目的 比较KAMIR评分与GRACE评分预测急性心肌梗死(AMI)患者一年死亡率的价值.方法 对收治128例AMI患者进行回顾性分析,计算KAMIR、GRACE评分,采用受试者工作特征曲线(ROC曲线),计算曲线下面积(AUC);KAMIR和GRACE的评分AUC比较采用Z检验.结果 KAMIR及GRACE评分预测AMI患者一年死亡率的AUC分别为0.880和0.792,两者比较差异有统计学意义(Z=2.524,P=0.0116).结论 KAMIR评分对预测AMI患者一年死亡率有较好的预测价值.%Objective To evaluate the predictive value of KAMIR and GRACE scores system score on predicting one - year mortality of acute myocardial infarction (AMI) patients. Methods One hundred and twenty - eight patients with AMI were retrospectively analyzed. The KAMIR and GRACE scores were calculated. The area under the receiver operating characteristic ( ROC ) curve ( AUC ) was evaluated using ROC curve. KAMIR, GRACE scores and AUC were analyzed by Z test. Results The AUCs of KAMIR and GRACE score for predicting one - year mortality of AMI patients were 0. 880 and 0. 792,respectively, which were significantly different between the two scores system(Z =2. 524,P = 0.0116). Conclusion KAMIR score is a better predictive factor of one - year mortality for AMI patients.
