摘要
目的分析常规心电图在心肌梗死相关冠状动脉病变评估中的意义。方法选定荥阳市人民医院心电图室2020年7月至2022年7月接受心电图检查的150例急性心肌梗死(AMI)患者设为病变组,另选取同期荥阳市人民医院体检中心150名健康体检者设为健康组,均给予常规心电图检查,以Gensin积分评估冠状动脉病变程度,比较2组QRS波时限、Gensin积分,比较不同冠状动脉病变程度组QRS波时限、Gensin积分,比较不同冠状动脉病变支数组QRS波时限、Gensin积分,Pearson相关分析QRS波时限与Gensin积分的相关性,绘制受试者工作特征曲线(ROC),分析QRS波时限对冠状动脉狭窄的诊断效能。结果病变组QRS波时限、Gensin积分均高于健康组,P<0.05。冠状动脉病变重度组QRS波时限、Gensin积分均高于中度组、轻度组,P<0.05。≥3支冠状动脉病变组QRS波时限、Gensin积分均高于双支冠状动脉病变组、单支冠状动脉病变组,P<0.05。QRS波时限与Gensin积分呈正相关性(r=0.41,P<0.05)。QRS波时限诊断冠状动脉狭窄的最佳截断值取68.34 ms时,曲线下面积(AUC)是0.903,95%CI(0.849,0.967),灵敏度是96.8%、特异度是91.1%。结论心肌梗死相关冠状动脉病变患者常规心电图QRS波时限呈异常高表达,且冠状动脉病变程度越重,QRS波时限越高,QRS波时限在诊断冠状动脉病变方面的灵敏度及特异度较高,具有一定的参考价值。
Objective To analyze the significance of routine electrocardiogram in the evaluation of myocardial infarction related coronary artery lesions.Methods A total of 150 patients with acute myocardial infarction(AMI)who received electrocardiogram examination from July 2020 to July 2022 in the ECG Office of Xingyang People's Hospital were selected as the lesion group,and another 150 healthy physical examination patients from the physical examination center of Xingyang People's Hospital during the same period were selected as the healthy group.All of them were given routine electrocardiogram examination.The degree of coronary artery disease was evaluated by Gensin integral,and the QRS duration and Gensin integral of the two groups were compared;the QRS duration and Gensin integral of the groups with different degrees of coronary artery disease were compared;the QRS duration and Gensin integral of the groups with different numbers of coronary artery disease were compared.Pearson analyzed the correlation between QRS duration and Gensin integral,drew receiver operating curve(ROC),and analyzed the diagnostic efficacy of QRS duration in coronary artery stenosis.Results QRS duration and Gensin scores in the pathological group were higher than those in the healthy group(P<0.05).The QRS duration and Gensin scores in severe coronary artery disease group were higher than those in moderate and mild groups,P<0.05.The QRS duration and Gensin scores in≥3 coronary artery disease group were higher than those in double coronary artery disease group and single coronary artery disease group(P<0.05).QRS duration was positively correlated with Gensin integral(r=0.41,P<0.05).When the best cutoff value of QRS wave duration in the diagnosis of coronary artery stenosis was 68.34ms,the AUC was 0.903,the 95%CI(0.849,0.967),the sensitivity was 96.8%,and the specificity was 91.06%.Conclusion The QRS duration of routine ECG in patients with myocardial infarction related coronary artery disease is abnormally high expression,and the more severe the degree of coronary artery disease,the higher the QRS duration,the higher the sensitivity and specificity of QRS duration in the diagnosis of coronary artery disease,has a certain reference value.
