摘要(Abstract)：
目的评价急性心肌梗死急诊冠状动脉介入治疗(PCI)中应用血栓抽吸导管(DIVERTM)的临床疗效与安全性。方法选择2005年3月至2006年4月符合急诊PCI治疗条件的急性心肌梗死患者共74例,入选患者梗死相关血管(IRA)100%闭塞伴冠状动脉内血栓,开通IRA后均置入西罗莫司药物涂层支架。其中36例(A组)将0.36mm(0.014in)BMW冠状动脉导丝送至闭塞血管远端,沿该导丝送入血栓抽吸导管(DIVERTM),持续负压下从血管近端至远端缓慢推抽2~3次,造影提示血栓影消失后直接置入支架;另外38例(B组)按常规方法完成PCI术。比较两组间血管开通率、无复流发生率、住院期间及出院后半年内心血管事件发生率。结果两组冠状动脉造影显示的血管开通率均为100%,A组无复流发生率及住院期间主要不良心脏事件发生率明显低于B组(2.78%比21.05%,2.78%比10.53%,P均<0.05)。平均随访3.2±1.4个月,随访率93.5%,两组半年内心血管事件发生率均为0。结论在急性心肌梗死急诊PCI中应用血栓抽吸导管(DIVERTM)安全可行,操作简单,能够明显减少冠状动脉内血栓,降低无复流和住院期间心血管事件发生率,其临床效果优于普通治疗组。
