摘要:目的分析影响急性心肌梗死急诊经皮冠状动脉介入治疗(PCI)后心电图ST段恢复的相关因素。方法患者行急诊PCI术后1h和术前患者的18导联心电图(ECG),测量并比较急诊PCI前后梗死相关导联最大ST段抬高幅度。按抬高的ST段下降幅度分为:A组,ST段下降≥50%;B组,ST段下降<50%。分析患者相关临床资料与ST段下降之间的关系。结果 2组患者性别、年龄未见明显差异;在糖尿病、梗死前心绞痛、梗死部位、Killips心功能分级、Q波计数、发病至急诊时间方面有显著差异;而在急诊至球囊开通时间以及梗死血管直径方面无显著差异。结论急性心肌梗死经急诊PCI术后心电图ST段恢复程度与糖尿病、梗死前心绞痛、梗死部位、Killips心功能分级、Q波计数、发病至急诊时间等有关,它们可能是影响ST段恢复的因素。

Abstract:Objective To analyze the factors related to ST-segment resolution in patients with acute myocardial infarction(AMI)after primary percutaneous coronary intervention(PCI).Methods The18-lead ECG before PCI and1h after PCI were to
the resolution of the ST-segment elevation in the infarct-related lead,the patients were classified into two groups;group A,with ST-segment resolution≥50%;group B,with ST-segment resolution<50%.The factors associated with ST-segment resolution were The differences between the2groups were not related to sex or age,the time from arriving at emergency roomto the start of PCI,or the diameter of the infarct-related -segment res-olution was found to be related to diabetes mellitus history,angina pectoris before MI,infarct area,Killip class of heart function,number of Qwaves,and the time from symptom onset to arrival at emergency The
