急性心肌梗塞患者发病前状况与其死亡率的相关性分析

The Relationship between The Epidemiology of Acute Myocardial Infarction and Its Mortality

目的:研究各种因素对急性心肌梗塞患者死亡率的影响。方法:总结分析某院近5年急性心梗患者临床资料。结果:早期入院组与晚期入院组患者年龄分布存在显著性差异(χ2=8.898,P=0.031)。当收缩压<80mmHg或舒张压<60mmHg时,AMI患者死亡率均明显高于其他组(分别为χ2=99.329,P=0.00;χ2=78.521,P=0.00)。发病前有无心绞痛对AMI患者死亡率有很大的影响(χ2=9.303,P=0.02);心肌梗塞面积对AMI死亡率有着重要的影响(χ2=25.016,P=0.00)。结论:心梗病人的年龄、血压、梗塞部位、范围及有无侧支循环直接关系到AMI患者病情的发展和预后。

Objective： To study the influencing factors of acute myocardial infarction＇s mortality. Methods： Collect the clinical datas of acute myocardial infarction in my hospital from 2002.08-2007. 12. Results： There was significantly difference on the age distribution of patients between admission in time and later（χ^2 = 8. 898, P = 0. 031） When SBP〈 80mmHg or DBP0mmHg, AMI＇s mortality was different from others （χ^2 = 99. 329,P=0. 00;χ^2 =78. 521 ,P=0. 00 respectively）. And angina pectoris was closely related to AMI＇s mortality（χ^2 = 9. 303, P = 0.02）. The myocardial infarct size was closely related to AMI＇s mortality, too（χ^2 = 25. 016,P=0.00）. Conclusion. The age, blood pressure, location of infarction and excentence of coronary collaterals were directly related the development and prognosis of patients with acute myocardial infarction
