摘要 目的观察冠心病患者药物洗脱支架(DES)植入术后球囊高压后扩张的临床疗效。方法选择冠心病患者656例,其中332例(观察组)冠状动脉DES植入术后予非顺应性球囊高压后扩张,324例(对照组)仅行DES植入术,记录术中及术后情况。结果两组血管病变情况、血管病变数量、植入DES数量、支架植入后管腔狭窄程度、术中并发症比较,P均>0.05。对照组支架植入后管腔最小直径为(2.74±0.32)mm、绝对内径获得为(2.25±0.40)mm,观察组分别为(3.13±0.34)、(2.63±0.47)mm,P均<0.05;对照组术后随访亚急性支架内血栓发生率为1.54%、晚期支架内血栓发生率为1.85%,观察组分别为0.30%、0.30%,P均<0.05。对照组术后12个月主要心脏不良事件发生率为6.79%、支架内再狭窄发生率为6.10%、支架最小内径为(2.37±0.38)mm、支架绝对内径丢失为(0.38±0.19)mm、管腔狭窄程度为18.70%±9.28%,观察组分别为2.41%、2.28%、(2.78±0.42)mm、(0.23±0.13)mm、13.50%±8.67%,P均<0.05。结论冠心病患者DES植入术后行球囊高压后扩张治疗可明显减轻管腔狭窄、减少绝对内径丢失,主要心脏不良事件发生率和支架内再狭窄发生率也明显降低。
