摘要 315例确诊的ST段抬高性急性心肌梗死(STEMI)患者,根据PCI术中是否出现再灌注心律失常(RA)分为RA组和NRA组,对比观察两组住院期间心脏性死亡、休克、心力衰竭等不良事件发生率。PCI术后30d彩超测定左室收缩末期内径(LVESD)、左室舒张末期内径(LVEDD)及左室射血分数(LVEF)。结果:RA组PCI时间窗显著早于NRA组,梗死相关动脉(IRA)开通距发病6 h内者占65%。与NRA组比较,RA有较高的ST段回落率,住院期间心力衰竭发生率及心脏性死亡率较低;术后30 d时RA组具较低的LVESD及较高的LVEF值。提示STEMI直接PCI术中RA更多发生于IRA开通较早者,RA可能提示更早期和充分的心肌再灌注,近期临床预后优于无RA者。
