摘要 目的 分析急性ST段抬高型心肌梗死并发心室颤动患者冠状动脉造影特点.方法 回顾性分析66例明确诊断为急性ST段抬高型心肌梗死并且在急性期出现心室颤动和接受急诊冠状动脉造影及直接经皮冠状动脉介入治疗的患者的临床资料.结果 ①临床特点:男55例(83.3%),女11例(16.7%),男性明显多于女性,差异有统计学意义(P<0.05).②心电图特征:66例患者中,41例(62.1%)为急性前壁心肌梗死,其中30例为急性广泛前壁心肌梗死,占73.2%;25例(37.9%)为下壁、正后壁心肌梗死,其中合并右心室梗死18例,占72.0%.③冠状动脉造影特征:41例急性前壁心肌梗死患者中,2例患者梗死相关动脉为左主干病变;余39例均为左冠状动脉前降支,罪犯病变在近段者28例,中段者9例,远段者2例,其中37例闭塞或中重度狭窄,轻度狭窄者2例.25例急性下壁心肌梗死中,7例(28.0%)患者梗死相关动脉为左冠状动脉回旋支,其中罪犯病变在近段者1例,中段者5例,远段者1例;18例(72.0%)患者梗死相关动脉为右冠状动脉,罪犯病变在近段者10例,中段者8例,均为重度狭窄或闭塞.66例患者中,多支病变46例(69.7%),其中三支病变25例(37.9%).结论 在急性ST段抬高型心肌梗死急性期合并心室颤动患者,以广泛前壁心肌梗死最为常见,下壁心肌梗死则常合并右心室梗死,左冠状动脉前降支作为梗死相关动脉最为常见,罪犯病变以近、中段重度狭窄或闭塞为主.
