摘要 目的:评价早期应用替罗非班对ST段抬高型急性心肌梗死(STEMI)患者急诊冠状动脉介入治疗(PCI)后心肌微循环灌注及安全性影响。方法:选择我院2009年1月至2011年1月心内科住院拟行PCI患者110例,年龄28~60岁,平均(46.2±8.1)岁;按随机数字表法分为PCI早期应用组(A组,在获取PCI知情同意后立即开始使用替罗非班者)和PCI即刻使用组(B组,在导丝通过冠状动脉病变后应用替罗非班),每组均55例。观察两组患者在常规使用阿司匹林和氯吡格雷基础上,PCI前后心肌梗死溶栓(Thrombolysis in Myocardial Infarction,TIMI)分级和梗死区心肌灌注(TIMI myocardial perfusion grade,TMPG)分级、血小板聚集以及出血等不良反应。结果:A组PCI前TIMI 3级和TMPG3级获得率分别为30.9%和34.5%,B组分别为12.7%和12.7%;PCI后A组分别为94.5%和80%,B组分别为84.7%和52.7%,两组PCI前TIMI 3级、TMPG3级及PCI后TMP3、TIMI3级比较差异有统计学意义(P<0.05)。A组和B组相比,血小板聚集率明显降低(P<0.05)。轻度出血并发症明显增多(P<0.05),重度出血并发症差异无统计学意义(P>0.05)。结论:在常规应用阿司匹林和氯吡格雷抗血小板治疗基础上,对≤60岁急性ST段抬高心肌梗死患者行急诊PCI,早期应用替罗非班能尽早抑制血小板聚集功能,明显改善梗死相关血管(infarction related artery,IRA)的血流及心肌微循环灌注,且未增加术后30d重度出血的概率。
