摘要(Abstract)：
目的评价西罗莫司洗脱支架(CypherTM支架)治疗急性心肌梗死的安全性及远期疗效。方法78例急性心肌梗死患者行急诊介入术时接受了CypherTM支架治疗,78处靶病变共置入97枚CypherTM支架。观察手术成功率、并发症、随访期间心脏不良事件发生率、再狭窄率及晚期管腔丢失等。结果在78处靶病变中,完全闭塞病变占82·3%,狭窄达95%以上的病变占17·7%。所有支架均成功置入,无残余狭窄或残余狭窄<10%,未见任何并发症。临床随访10·0±3·6(6~15)个月,临床随访率100%,有2例症状复发,后经冠状动脉造影证实为支架内再狭窄所致,需再次血运重建,其余患者均未发生任何心脏不良事件,无1例死亡。64例患者术后9±2·2(6~14)个月复查了冠状动脉造影,造影随访率82·1%,支架近端边缘节段平均晚期管腔丢失(0·24±0·05)mm;支架内平均晚期管腔丢失(0·19±0·03)mm,支架远端边缘节段平均晚期管腔丢失(0·10±0·02)mm。靶病变再狭窄率为3·1%(2/64),病例复发率为3·1%(2/64),再次血运重建率为3·1%(2/64)。结论CypherTM支架治疗急性心肌梗死是安全可行的,其近期及术后9个月内的疗效是满意的,它能显著降低9个月内的支架内再狭窄率及再次血运重建率。
