摘要(Abstract)：

目的探讨血栓负荷重对老年ST段抬高急性心肌梗死患者急诊经皮冠状动脉介入治疗(PCI)预后的影响。方法73例老年ST段抬高急性心肌梗死患者在发病12h内行急诊PCI。根据冠状动脉造影后血栓负荷状态分为血栓负荷重组(n=26)和血栓负荷轻组(n=47),同时监测PCI后血流、肌酸激酶MB型同工酶(CK-MB)峰值、住院期间的射血分数(EF)和病死率。结果梗死相关血管内血栓负荷过重的发生率为35.6%,多见于右冠状动脉内。血栓负荷重组患者行PCI后TIMI3级血流的发生率明显低于血栓负荷轻组;血栓负荷重组的CK-MB峰值和近期死亡率明显高于血栓负荷轻组。结论血栓负荷过重是老年急性心肌梗死患者急诊PCI预后的危险因素。
