简单风险指数对急性ST段抬高性心肌梗死患者住院死亡率的预测价值

目的：评价简单风险指数（SRI）对急性ST段抬高性心肌梗死（STEMI）病人住院死亡率的预测价值。方法：心内科CCU收住的符合条件的STEMI病人共133例为研究对象，比较死亡组与存活组一般临床资料、ST段抬高导联数、ST抬高指数（STI）、治疗方案及SRI值的差别，分析各计量资料的相关关系，检验全部观察变量中影响预后的主要因素。结果：两组年龄、ST段抬高导联数、SRI值存在显著差异（P〈0．05）；SRI与ST抬高导联数具统计学意义的正相关关系（r=0．305）；Logistic回归分析显示SRI及ST抬高导联数是STEMI预后的独立危险因子。结论：SRI评分越高，病人心脏受损的导联数越多，死亡危险性越大，SRI是STEMI病人住院死亡的快速、有效预测因子。

Value of a Simple Risk Index to Predict in-hospital Mortality in ST-segment Elevation Myocardial Infarction

Objective: To evaluate the value of a simple risk index(SRI) which predict in-hospital mortality in ST-segment elevation myocardial infarction(STEMI).Methods: Totally 133 STEMI patients were enrolled,24 patients died(group 1),109 patients survived(group 0).Basic characteristics,therapy methods,the number of ST-segment elevation lead,ST-segment elevation index(STI) and the simple risk index(SRI) in the two groups of patients were compared.Continuous data were compared with their correlations.All variables were tested to find which was the mainly factor that influenced prognosis. Results: There were statistical differences between the two groups on age,the number of ST-segment elevation leads,SRI(P<0.05),and SRI vs number of ST-segment elevation leads(r=0.305,P<0.05).SRI and number of ST-segment elevation leads were the mainly factors that influenced prognosis.Conclusion: The SRI is a convenient and effective tool to be used in the rapid triage of patients with STEMI outside the hospital or on first arrival in the hospital and it can effectively predict in-hospital mortality in STEMI patients.
