摘要 目的观察ST段抬高型心肌梗死(STEMI)患者行直接经皮冠状动脉介入(PCI)后碎裂QRS(fQRS)波的发生情况及其相关因素。方法直接PCI的STEMI患者224例,根据PCI后48 h心电图是否存在fQRS波分为fQRS组和非fQRS组。PCI后应用TIMI血流分级和心肌呈色分级(MBG)分析冠脉血流情况和心肌灌注情况。应用Logistic回归分析评估fQRS波与各因素之间的关系。结果 PCI后78例患者出现fQRS波群,占34.8%。与非fQRS组相比,fQRS组的年龄较大,吸烟率较高,HDL-C较低,CM-MB峰值较高,ST段抬高的导联数目和下壁心肌梗死较多,发病至球囊扩张时间较长,MBG分级<3级的比例较高。Logistic多元回归分析显示,MBG<3级、CK-MB峰值水平、心肌梗死部位、发病到球囊扩张时间为直接PCI后出现fQRS波的独立影响因素。结论 STEMI患者PCI术后有较多的患者出现fQRS,相关因素有MBG<3级、CK-MB峰值水平、心肌梗死部位、发病到球囊扩张时间。
