摘　　要：【目的】探讨稳定型心绞痛患者心电图aVL导联T波改变与冠状动脉狭窄程度的相关性。【方法】回顾性分析2018年5月至2021年5月本院收治的90例稳定型心绞痛患者的临床资料,根据患者预后情况将患者分为预后良好组(n=60)和预后不良组(n=30)。比较两组一般资料、血清指标[心肌肌钙蛋白I(cTnI)、超敏C反应蛋白(hs-CRP)、脑钠肽(BNP)、肌酸激酶同工酶MB(CK-MB)],比较不同aVL导联T波改变情况,患者冠状动脉狭窄程度,采用多因素Logistic回归分析预后不良的独立危险因素。【结果】预后不良组aVL导联T波改变、ST段抬高、病理性Q波、冠状动脉狭窄占比高于预后良好组,差异有统计学意义(P<0.05)。Logistic回归分析显示,aVL导联T波改变、ST段抬高、病理性Q波、冠状动脉狭窄均为稳定型心绞痛患者预后不良的危险因素(P<0.05)。根据不同aVL导联T波改变情况将患者分为T波改变组和无T波改变组。T波改变组前降支中段狭窄程度高于无T波改变组,差异有统计学意义(P<0.05)。【结论】aVL导联T波改变、ST段抬高、病理性Q波、冠状动脉狭窄是影响稳定型心绞痛患者预后不良的危险因素,且aVL导联T波改变还可预测冠状动脉前降支中段狭窄程度。【Objective】To investigate the correlation between T-wave changes in lead aVL on electrocardiogram(ECG)and the degree of coronary artery stenosis in patients with stable angina pectoris.【Methods】The clinical data of 90 patients with stable angina pectoris admitted to our hospital from May 2018 to May 2021 were retrospectively analyzed.Based on prognosis,the patients were divided into a good prognosis group(n=60)and a poor prognosis group(n=30).General data and serum markers[cardiac troponin I(cTnI),high-sensitivity C-reactive protein(hs-CRP),brain natriuretic peptide(BNP),and creatine kinase-MB(CK-MB)]were compared between the two groups.The degree of coronary artery stenosis was compared among patients with different T-wave changes in lead aVL.Multivariate logistic regression analysis was used to identify independent risk factors for poor prognosis.【Results】The proportions of T-wave changes in lead aVL,ST-segment elevation,pathological Q waves,and coronary artery stenosis were significantly higher in the poor prognosis group than in the good prognosis group(P<0.05).Logistic regression analysis showed that T-wave changes in lead aVL,ST-segment elevation,pathological Q waves,and coronary artery stenosis were all risk factors for poor prognosis in patients with stable angina pectoris(P<0.05).Based on T-wave changes in lead aVL,patients were further divided into a T-wave change group and a no T-wave change group.The degree of mid-segment stenosis in the left anterior descending artery was significantly higher in the T-wave change group than in the no T-wave change group(P<0.05).【Conclusion】T-wave changes in lead aVL,ST-segment elevation,pathological Q waves,and coronary artery stenosis are risk factors for poor prognosis in patients with stable angina pectoris.Moreover,T-wave changes in lead aVL can predict the degree of mid-segment stenosis in the left anterior descending artery.
