摘要(Abstract)：

目的评价急性心肌梗死患者行急诊PCI时在应用血栓抽吸导管进行血栓抽吸前后冠状动脉内注射替罗非班对患者的心肌再灌注、心功能以及主要心脏事件的影响。方法取2009年9月至2011年11月在常平医院行急诊PCI治疗的急性ST段抬高型心肌梗死153例,按数字表法随机分为两组,其中一组在造影术后,血栓抽吸前立即冠状动脉内注射替罗非班15ml,另一组在血栓抽吸术后冠状动脉内注射替罗非班15ml,评价PCI术后两组间造影结果以及左室射血分数、MACE的情况等等。结果在血栓抽吸前冠状动脉内注射替罗非班组MBG2、3级的比例为85.0%,而在血栓抽吸后冠状动脉内注射替罗非班组的比例为67.1%,差异具有统计学意义。出院前LVEF值分别为71.5±10.0和61.5±11.0,差异具有统计学意义。而冠状动脉内TIMI3级血流、CTFC帧数、以及ST段回落率在两组间的差异没有统计学意义。结论在急性ST段抬高型心肌梗死患者行PCI时,如果患者血栓负荷过重,在支架置入术前先行冠状动脉内替罗非班注射,然后再进行血栓抽吸可以得到更好的心肌再灌注,并且对LVEF的改善有益。
