1827例急性心肌梗死患者梗死部位的相关分析

目的　调查不同部位急性心肌梗死患者梗死的发病特点。方法　通过回顾病史 ,将符合诊断标准的住院患者按照不同发病部位分组 ,分别记录发病特点 ,了解不同发病部位的构成比 ,不同发病部位的男女构成比以及发病部位与病死率的关系。结果　符合条件的病例共 182 7例 ,前壁急性心肌梗死 (前壁、前间壁和广泛前壁 )占总发病的 4 5 8% ,其次是下壁急性心肌梗死组占 2 6 7%。在所有部位急性心肌梗死病例中 ,男性发病比例 (6 4 0 %～ 88 3% )与女性 (11 7%～ 36 0 % )相比均有很大差别 (P <0 0 5 )。各部位急性心肌梗死的病死率为 8 7%～ 2 0 6 %。除急性前壁合并下壁组心肌梗死病例病死率差异有显著性外 (P <0 0 5 ) ,其他部位急性心肌梗死患者的病死率与急性心肌梗死平均住院病死率相比差异未见显著性(P >0 0 5 )。结论　急性心肌梗死以前壁或下壁为主 ,男性仍是发生急性心肌梗死的主要人群 ,急性前壁和合并下壁心肌梗死的病死率显著高于急性心肌梗死平均病死率。

Investigation of infarction position in 1827 patients with acute myocardial infarction

Objective To investigate the characteristics of acute infarction in different locations.Methods A retrospective study was carried out in the patients with acute myocardial infarction. The patients were divided into different groups according to the infarction walls.Results There were 1 827 patients who matched the diagnosis criterion of acute myocardial infarction. The patients with infarction of the anterior wall accounted for 45.8 %, while 26.7 % were infarction of the inferior wall. Among all the groups, the incidences in male patients ranging from 64.0% to 88.3% were higher than those of the female patients with 11.7% to 36.0%. There was significant difference between males and females (P<0.05).The group of acute myocardial infarction with both anterior and inferior walls had a significant higher mortality than the average mortality (P<0.05).Conclusion Anterior or inferior wall of the ventricle were the two most common of myocardial infarction.Male had the higher risk of acute myocaridial infarctions. Patients with acute infarction of both anterior and inferior walls have a markedly increased mortality.
