摘　　要：目的　分析血清肌钙蛋白I(cTnI)峰浓度与心电图Q波、ST段的相关性 ,以了解它们在急性心肌梗死 (AMI)病情和预后判断中的作用。方法　 172例急性心肌梗死患者在不同时间段系列采血测定血清cTnI峰浓度 ,检查标准 18导联心电图 ,统计出现病理性Q波的导联数 ,病理性Q波总幅度 ,最大病理性Q波 ,ST段抬高的导联数 ,并与血清cTnI峰浓度比较。同时考虑对冠脉再灌注的影响。结果　不论再通与否 ,AMI(包括前壁、下壁 )患者标准 18导联心电图病理性Q波的总幅度、最大病理性Q波幅度、出现病理性Q波的导联数目以及急性前壁心肌梗死ST段抬高的导联数目与血清cTnI峰浓度有明显的等级相关性。结论　急性心肌梗死患者血清cTnI峰浓度与心电图病理性Q波的总幅度、最大病理性Q波幅度。Objective It is to study the role of serum cTnI peak concentration and Q wave, ST section in judgment of the clinic condition and prognosis of AMI patients by comparing the relationship between them. Methods Blood samples for cTnI measurement were collected at admission and all following time points in 172 cases of AMI. Standard 18-conductor electrocardiogram (ECG) was checked. The numbers of pathologic Q waves, elevated ST sections and the assemble extents of pathologic Q wave and maximum extent of pathologic Q wave in each ECG was calculated. The relationship between them and serum cTnI peak concentration was investigated. Results There was a significant rank correlation among the numbers of pathologic Q waves and elevated ST sections, the assemble extents of pathologic Q wave, the maximum extent of pathologic Q wave and serum cTnI peak concentration. Conclusions Serum cTnI peak concentration and ECG indices above are helpful to prognosis.
