摘要
目的探讨心电图缺血分级与急性心肌梗死(AMI)罪犯冠脉狭窄程度的相关性。方法回顾性收集2018年6月至2020年6月于我院接受治疗的73例急性心肌梗死患者临床资料,根据Birnbaum心电图缺血分级结果,分为Ⅱ级组(n=45)与Ⅲ级组(n=28),比较两组AMI罪犯冠脉狭窄情况,并分析心电图缺血分级与AMI罪犯冠脉狭窄程度的相关性。结果Ⅱ级组管腔狭窄程度、罪犯冠脉病变数目、心肌梗死面积均低于Ⅲ级组,差异有统计学意义(p<0.05);经Logistic回归分析检验得到方程:Y=-51.737+2.137X1+40.629X2+3.156X3,提示罪犯冠脉狭窄指标可能是老年AMI患者心电图缺血分级的影响因素(OR>1,p<0.05);绘制ROC曲线,结果显示,罪犯冠脉狭窄指标联合预测AMI患者心电图缺血分级的AUC为0.917,具有较高的诊断价值。结论急性心肌梗死患者心电图缺血分级与罪犯冠脉狭窄情况密切相关,且罪犯冠脉狭窄是诱发心肌缺血的影响因素,临床可加强对患者罪犯冠脉狭窄情况的监测,为临床实施合理的预防与治疗方案提供理论基础。
Objective To investigate the correlation between electrocardiogram ischemia grade and target vessel stenosis in acute myocardial infarction(AMI). Methods Retrospectively collected in June 2018 to June 2020 in our hospital for treatment of 73 cases of acute myocardial infarction patients with clinical data, according to the Birnbaum ischemia ECG classification result, divided into Level Ⅱ group(n=45) and Level Ⅲ group(n=28), compare the two groups of AMI target vascular stenosis, and analyze ECG ischemia classification with AMI narrow correlation target blood vessels. Results In level Ⅱ group, the degree of luminal stenosis, the target number of vascular lesions,myocardial infarction area was lower than Level Ⅲ group, the difference was statistically significant(p<0.05). The equation was obtained by Logistic regression analysis: Y=-51.737+2.137 X1+40.629 X2+3.156 X3, suggesting that target vascular stenosis may be an influential factor in the ischemic grade of ECG in elderly patients with AMI(OR>1,p<0.05). ROC curve was drawn, and the results showed that the AUC of target vascular stenosis combined with the prediction of electrocardiogram ischemia grade in AMI patients was 0.917, which was of high diagnostic value.Conclusions ECG ischemia grade in patients with AMI is closely related to target vessel stenosis, and target vessel stenosis is an influential factor in inducing myocardial ischemia. Clinical monitoring of target vessel stenosis in patients can be strengthened, providing a theoretical basis for clinical implementation of reasonable prevention and treatment programs.
