心肌梗死部位与危险因素及预后的相关性探讨

The study of correlation of myocardial infarction sites with risk factors and its prognosis

急性心肌梗死的部位是决定心肌梗死预后的重要因素，为此作者研究了１７９例急性前壁和下壁心梗（包括非Ｑ波性心梗）梗死部位与危险因素的差别及对住院病死率和并发症的影响。本文结果提示前壁心梗患者中，不吸烟者较下壁心梗患者中多，且前壁心梗患者中有高血压和高血脂者多，机械并发症多，预后差，病死率高。房室传导阻滞多见于下壁心梗，非Ｑ波心梗并发症少于有Ｑ波心梗患者。

This is a study of the relationship between the infarction sites and both risk factors and inhospital outcome in 179 consecutive patients admitted with myocardial infarctions. The number of non smokers in the patients with anterior infarctions was greater than that in the patients with inferior infarctions. But the patients with anterior infarctions had a higher prevalence of hypertension and a higher mean cholesterol level. Inhospital prognosis was worse in anterior infarctions with significantly higher rates of death and complications. Atrioventricular blocks were more common in inferior infarctions. Non Q wave infarctions had a lower incidence of complications than Q wave infarctions
