介入相关性心肌梗死与预后的关系
Journal of Medical Research(2017)
Abstract
目的 研究经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后发生介入相关性心肌梗死对预后的影响.方法 选择行PCI术治疗的患者共360例,根据是否发生介入相关性心肌梗死分为心肌梗死组及非心肌梗死组,观察术后6个月超声心动图较术前相比左心室射血分数变化量(ΔLVEF)以及随访过程中主要不良心血管事件(the major adverse cardiovascular events,MACE)发生率.结果 ΔLVEF心肌梗死组与非心肌梗死组比较差异有统计学意义(P=0.002);MACE发生率心肌梗死组与非心肌梗死组比较差异有统计学意义(P=0.004);分层分析示,对于非旋磨患者,介入相关性心肌梗死与ΔLVEF(P=0.000)及MACE(P =0.004)相关,在旋磨患者中,介入相关性心肌梗死与ΔLVEF(P=0.857)及MACE(P=0.241)未见同样的相关性.结论 介入相关性心肌梗死对于非旋磨的患者发生左心室射血分数下降、MACE发生具有预测价值,在旋磨患者中则并未显示相应的预测性.
