摘要 目的比较急性心肌梗死(AMI)患者心电图改变与心肌酶学指标变化在AMI超急性期的诊断意义。方法对我院从2005年1月到2009年11月共306例急性心肌梗死患者进行回顾性分析,根据发病时间分为3组,A组(发病时间<2h,n=98)、B组(发病时间在2~6h以内,n=129)和C组(发病时间超过6h,n=79)。分别比较两组患者一般资料、心电图和心肌酶学指标改变等情况。结果发现各组之间J点抬高和ST段抬高的比例都明显升高,无显著性差异(P>0.05);而ST段缩短和T波高尖的比例,三组差异明显,A组明显升高。三组患者心肌酶学指标的升高时间无明显差异。A组中高中或以上学历比例与B、C组比较明显升高,干部成分的比例也高于后两组。结论急性心肌梗死发生的前2h内,心肌代谢改变所导致的心电图改变远远早于心肌酶学指标改变,加强AMI超早期心电图特征的学习和应用,有利于AMI患者的及时诊断和有效治疗。
