【摘要】 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更多还原

【Abstract】 Objective To investigate the relationship of clinical characteristics and angiographic results in patients with acute inferior myocardial infarction Methods 62 patients with acute inferior myocardial infarction had accepted CAG and ECG examination Results In patients with LAD lesions, the incidence of hypertension, smoking, diabetes mellitus and hyperlipoidemia were 29 7%, 70 3%, 21 6% and 37 9% respectively; on the other hand, in the group without LAD lesions were 9 1%, 0%, 68 3% and 31 9%, respectively All patients were divided into four groups according to ECG appearance The occurence rate of LAD lesion was 33 3% in group Ⅰ, 16 7% in group Ⅱ, 81 0% in group Ⅲ and 75 0% in group Ⅳ, respectively Conclusion The precordial ST segment depression in V 1 6 or V 4 6 in patients with acute inferior myocardial infarction suggests the presence of LAD lesion Patients with inferior AMI and diabetes mellitus at the same time have LAD lesion mostly更多还原
