摘　　要：目的研究老年急性心肌梗死(AMI)患者心电图QRS时限与预后的相关性。方法选取老年AMI患者204例,按心电图QRS时限是否>110 ms,分为QRS时限正常组87例(QRS时限≤110 ms),QRS时限延长组117例(QRS时限>110 ms)。检测N末端脑钠肽前体(NT -proBNP)浓度,LVEF,观察Killip分级、主要不良心血管事件(MACE)的发生率、住院心源性死亡发生率。结果 2组的NT-proBNP、LVEF、KillipⅡ～Ⅳ级、MACE发生率及心源性死亡发生率比较有显著差异(P<0.05,P<0.01)。结论老年AMI患者心电图QRS时限延长的预后差,心力衰竭、MACE和心源性病死率发生率高。Objective To study the relation between electrocardiographic QRS duration and prog- nosis of elderly patients with acute myocardial infarction（AMI）. Methods Two hundred and four elderly AMI patients were divided into normal QRS duration group（n=87） and prolonged QRS duration group（n=117） according to whether their electrocardiographic QRS duration was 〉110 ms. Their NT-proBNP level and LVEF were measured. Killip classification, incidence of major adverse cardiovascular events（MACE）, and cardiogenic mortality in hospital were observed and recorded. Results The NT-proBNP,LVEF,Killip grades Ⅱ-Ⅳ and the incidence of MACE and cardiogenic mortality were significantly different between the two groups（P〈0.05, P〈0.01）. Conclusion The prognosis of elderly AMI patients with a prolonged electrocardiographic QRS duration is poor with a high incidence of heart failure, MACE and cardiogenic mortality.
