摘要(Abstract)：

目的探讨血管内超声(IVUS)在ST段抬高型心肌梗死(STEMI)患者急诊介入诊疗中的应用。方法选择冠状动脉造影(CAG)提示心肌梗死相关血管(IRA)固定狭窄为临界病变的STEMI患者80例,发病在12小时内,并且远端血流TIMIⅢ级;随机分为IVUS组(试验组)38例和未行IVUS组(对照组)42例;对照组全部置入支架,试验组进一步经IVUS评价病变分为低危和高危患者,决定是否置入支架;观察两组患者住院期间、术后1个月、3个月、6个月、1年心脏主要不良事件发生率,左心室舒张末期内径(LVEDD)及射血分数(EF)值的变化,支架置入的个数。结果两组患者住院期间、术后1个月、3个月、6个月、1年心脏主要不良事件发生率比较无明显差异,两组LVEDD及EF值比较无明显差异(P>0.05);试验组比对照组支架置入的个数减少,差异有显著性(P<0.05)。结论在IVUS指导下的急诊介入诊疗中,STEMI低危患者不置入支架也是安全的、可行的,减少了患者支架置入数量。
