摘要 目的探讨心电图V1导联P波终末电势(PTFV1)对冠心病陈旧性心肌梗死患者预后的意义;进一步探讨心电图V1导联中P波双向和P波负向对冠心病陈旧性心肌梗死患者预后是否有所不同。方法入选冠心病心肌梗死病史大于6个月的患者185例,在医院进行过冠脉造影检查并随访。PTFV1≥40mm×ms为PTFV1异常组,PTFV1<40mm×ms为PTFV1正常组,心电图PTFV1异常组再分为V1导联P波负向组和V1导联P波双向组,分别比较2组无主要事件发生率。结果与PTFV1正常组相比,心电图PTFV1异常组无主要事件发生率降低(P<0.01)。心电图PTFV1异常而V1导联P波负向的患者和心电图PTFV1异常而V1导联P波双向的患者,无主要事件发生率无差别。多变量Cox回归分析结果PTFV1异常(HR2.721,95%CI1.237~5.987,P=0.013)是主要终点的独立预测因子(P<0.05)。结论心电图PTFV1异常是冠心病陈旧性心肌梗死患者心脏性死亡或因心力衰竭住院的独立预测因子。心电图PTFV1异常中V1导联P波负向的患者和V1导联P波双向的患者,主要终点事件发生率没有差别。分析心电图PTFV1为冠心病心肌梗死患者提供了有用的预后信息。
