摘要
目的 探讨急性前壁心肌梗死患者入院时心电图下壁导联 ST段下移与临床预后及左冠状动脉前降支“罪犯”血管病变部位之间的关系。方法 选择 1998年 1月~ 2 0 0 2年 10月住院诊治并行冠状动脉造影的急性前壁心肌梗死患者 5 9例 ,依据冠状动脉造影所示左前降支“罪犯”血管病变部位与第一对角支起始部的关系分成两组 , 组 36例病变部位位于第一对角支发出前 , 组 2 3例病变位于第一对角支发出后。结果  组 36例占 6 1.0 1% , 组 2 3例占 38.98%。 组病人多数合并下壁导联 ST段下移≥ 1mm ,在 、 、a VF导联分别为 81% ,92 % ,79%。 组多数 ST段位于等电位线或 ST段下移 <1m m,在 、 、a VF导联分别为 6 0 % ,6 1% ,5 3%。结论 急性前壁心肌梗死患者入院时心电图下壁导联 ST段下移可以预测“罪犯”血管病变部位位于第一对角支起始部近端 ,而 ST段位于等电位线或 ST段下移 <1mm预示病变部位位于前降支远端
