摘要 目的探讨直接经皮冠状动脉介入(PCI)、延迟PCI对心电图表现包含缺血性J波急性心肌梗死的预后影响。方法80例急性心肌梗死(ST段抬高型合并J波综合征)患者分为直接PCI组和延迟PCI组,各40例。观察发病后24h至3周各种疗法对J波的持续时间、恶性室性心律失常发生率、左心室功能及射血分数、心率变异等指标的影响。结果直接PCI组J波持续时间与延迟PCI组持续时间比较差异无显著性,但直接PCI组出现恶性心律失常发生率明显低于延迟PCI组,左心功能下降及射血分数下降低于延迟组,而心率变异性(HRV)时域指标(SDNN)延迟PCI组较直接PCI组明显下降(<0.05)。结论心电图表现包含缺血性J波的急性冠脉综合征患者经直接PCI治疗各参数改善均优于延迟组,提高对缺血性J波的认识水平,建议把缺血性J波作为急性冠脉综合征的预警信号,为直接PCI治疗赢得时间。
