摘要
目的探讨急性冠状动脉综合征患者avL导联T波改变对预后的预测意义。方法选择急性冠状动脉综合征患者142例,行心电图与冠状动脉造影检查,记录影像学特征。随访患者的预后,根据预后情况分为预后不良组和预后良好组,并对观察项目进行相关性分析。结果142例患者中42例患者(预后不良组,29.6%)到达心血管事件终点,100例患者预后良好(预后良好组,70.4%)。预后良好组avL导联T波改变发生率为13.0%,显著低于预后不良组的85.7%(P<0.05);预后良好组ST段抬高、ST段压低、病理性Q波等发生率也显著低于预后不良组(P<0.05)。预后不良组冠状动脉狭窄率显著高于预后良好组(P<0.05)。COX模型分析显示冠状动脉狭窄率、avL导联T波改变、ST段抬高、病理性Q波具有独立的预后预测价值(P<0.05)。结论急性冠状动脉综合征患者avL导联T波改变可预测其预后,avL导联T波改变是患者心血管事件终点发生的独立危险因素。
Aim To investigate the predictive value of T wave changes in avL lead in patients with acute coronary syndrome.Methods Electrocardiogram and coronary angiography were performed in 142 patients with acute coronary syndrome,and imaging features were recorded.The prognosis of the patients were followed up.The prognosis group and the prognosis group were classified accorded to the prognosis,and the correlation analysis were performed on the observation items.Results There were 42 patients(poor prognosis group,29.6%)were reached the end of the cardiovascular event,and 100 patients were good prognosis(good prognosis group,70.4%).The the avL lead T wave change rates in the good prognosis group were 13.0%,which were significantly lower than 85.7%in the poor prognosis group(P<0.05).The ST segment elevation,ST segment depression,pathological Q wave,etc in the good prognosis group were significantly lower than the poor prognosis group(P<0.05).The rates of coronary artery stenosis in the good prognosis group were significantly higher in the poor prognosis group(P<0.05).COX model analysis showed that coronary stenosis rate,avL lead T wave change,ST segment elevation,and pathological Q wave had independent prognostic value(P<0.05).Conclusion T-wave changes in the avL lead in patients with acute coronary syndrome can predict their prognosis,and the T-wave change in the avL lead is an independent risk factor for the endpoint of cardiovascular events in patients.
