目的 探讨急性下壁心肌梗塞患者临床与冠状动脉造影特点之间关系。方法 对６２ 例急性下壁心肌梗塞患者的临床特点与冠状动脉造影结果进行回顾性分析。结果 ３ 例冠状动脉造影结果正常；５９ 例异常者中，合并前降支病变组中糖尿病、高血压、吸烟和高脂血症的发生率分别为２１．６％ 、２９．７％ 、７０．３％ 、３７．９％ ；在未合并前降支病变组中分别为：０％ 、９．１％ 、６８．３％ 和３１．９％ 。根据心电图改变分为：Ⅰ组、Ⅱ组、Ⅲ组和Ⅳ组的前降支病变发生率分别为：３３．３％ 、１６．７％ 、８１．０％ 和７５．０％ 。结论 急性下壁心肌梗塞合并糖尿病或伴心电图广泛前壁（Ｖ１－６）或前侧壁（Ｖ４－６）ＳＴ 段下降者，大多合并前降支病变
Objective To investigate the relationship between clinical characteristics and coronary angiography in patients with acute inferior myocardial infarction. Methods The clinical features and coronary angiography findings of 62 patients with acute inferior myocardial infarction were retrospectively analyzed. Results The results of coronary angiography were normal in 3 cases. The incidence of diabetes, hypertension, smoking and hyperlipidemia was 21.6%, 29.7% and 70 respectively in 59 cases of abnormalities. 3% and 37.9%, respectively; 0%, 9.1%, 68.3% and 31.9% in the group of non-combined anterior descending coronary artery disease respectively. According to the change of electrocardiogram, the incidences of anterior descending coronary artery disease were 33.3%, 16.7%, 81.0% and 75.0% respectively in group Ⅰ, group Ⅱ, group Ⅲ and group Ⅳ. Conclusions Acute inferior myocardial infarction combined with ST-segment decline in the anterior wall (V1-6) or anterior wall (V4-6) of diabetes mellitus or with ECG, most of them complicated with anterior descending coronary artery disease
