摘要(Abstract):
目的 评价改良球囊拘禁技术(MJBT)在冠状动脉分叉病变介入治疗过程中应用的效果。方法 选择2022年10月至2023年12月在沧州市中心医院心血管内科医学中心行经皮冠状动脉介入治疗(PCI)的冠状动脉分叉病变患者110例。应用MJBT(MJBT组)54例患者,应用标准拘禁导丝技术(JWT组)56例患者。比较两组患者基线资料、PCI相关资料、随访12个月主要不良心血管事件(MACE,包括心源性死亡、再次住院、急性心肌梗死和靶病变血运重建)。结果 两组患者基线临床资料比较,差异均无统计学意义(均P>0.05)。MJBT组与JWT组相比,手术时间及X线曝光量比较,差异均无统计学意义(均P>0.05)。MJBT组支架置入即刻成功率高于JWT组(85.2%比64.3%,P=0.012),导丝再次进入分支比例低于JWT组(18.5%比37.5%,P=0.029),导丝再次进入分支的时间比JWT组明显减少[(7.20±1.81)min比(11.48±8.70)min,P=0.038],差异均有统计学意义。所有患者在住院期间均未发生支架内血栓形成等不良事件。随访12个月两组MACE发生率比较,JWT组5.4%(3/56),MJBT组1.9%(1/54),差异无统计学意义(P>0.05)。两组患者均未发生急性心肌梗死、急性支架内血栓形成及死亡事件。结论 MJBT在冠状动脉分叉病变介入治疗过程中可以提高介入手术的即刻成功率,减少再次进入分支的时间,进而保证分支血流,为冠状动脉分叉病变介入治疗分支保护提供了一种新方法。
