摘要 目的:探讨血清心肌肌钙蛋白I(cTnI)峰浓度与心电图(ECG)ST段抬高、病理性Q波对早期估测急性心肌梗死(AMI)患者病情及预后的作用。方法:对120例AMI患者在来急诊24h内不同时间段采血测定cTnI峰浓度,同时检查标准18导联ECG,分别统计出不同ST段抬高及病理性Q波的导联数之间血清cTnI峰浓度的变化。结果:ST段抬高数目中A(2~3个)、B(4~5个)、C(≥6个)3组血清cTnI峰浓度组间比较,分别计算q=3.590、7.572和5.236,P<0.05或<0.01;病理性Q波数目中D(0~3个)、E(4~5个)、F(≥6个)3组血清cTnI峰浓度组间比较,分别计算q=5.361、4.392和4.573,P<0.01,差异有显著性。结论:cTnI峰浓度与ECG出现ST段抬高和病理性Q波的导联数有密切关系,对早期判断AMI患者的病情及预后有重要意义。
