目的:探讨急性ST段抬高型心肌梗死(STEMI)患者的住院死亡情况,分析与住院病死率相关的影响因素。方法:收集2007年9月～2010年8月潍坊市人民医院心内一科402例急性心肌梗死患者的病历资料,比较病死组与存活组患者各项指标情况异同,分析与住院病死率相关的各项影响因素。结果:STEMI患者的住院病死率为8.0%(32/402)。STEMI住院死亡患者主要特点:年龄大,左室排血功能(LVEF)低,Kjllip分级高,肾功能不全,休克的发生率高,β-受体阻断药使用率低,接受经皮冠状动脉介入治疗率低。Binary logistic多元回归分析显示高龄、Killip分级高、β-受体阻断药使用率低是STEMI患者住院病死率的独立危险因素。结论:高龄、心功能Killip分级高、β-受体阻断药使用率对STEMI患者的住院期间病死率具有显著影响。
Objective: To investigate the in-hospital mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) and to analyze the influencing factors associated with in-hospital mortality. Methods: The data of 402 cases of acute myocardial infarction in the First Department of Cardiology of Weifang People’s Hospital from September 2007 to August 2010 were collected. The differences of each index between the patients who died and those who survived were analyzed. Various factors. Results: In-hospital mortality was 8.0% (32/402) in STEMI patients. The main characteristics of STEMI in-hospital death were age, low left ventricular ejection fraction (LVEF), high Kjllip grade, renal insufficiency, high incidence of shock, low β-blocker use, and percutaneous coronary intervention Interventional treatment rate is low. Binary logistic multiple regression analysis showed that elderly patients with high Killip grade and low β-blocker use were independent risk factors for in-hospital mortality in STEMI patients. CONCLUSION: Elderly patients with high Killip heart function and the use of β-blockers have a significant effect on the in-hospital mortality of STEMI patients.
