心电图及超声心动图对缺血性心脏病责任血管的预测价值

Predictive Value of ECG and Echocardiography in Predicting the Responsible Blood Vessels of Ischemic Heart Disease

目的:探讨心电图(ECG)及超声心动图与缺血性心脏病责任血管的相关性。方法:缺血性心脏病患者2 568例行冠状动脉造影术,以造影检查结果作为评价标准,将ECG及超声心动图的诊断结果与缺血性心脏病责任血管的关系进行分析。结果:冠状动脉单支病变组发病率高,占73.93%,单支病变组中以前降支发病率高,占63.59%;ECG及超声心动图阳性改变与冠状动脉单支病变组、双支病变组、三支病变组有预测预测价值(P=0.000);ECG阳性改变对预测前降支狭窄敏感性有高于回旋支、右冠状动脉的趋势,但无差异无统计学意义(P=0.539);超声心动图阳性改变对预测前降支、回旋支、右冠状动脉病变差异有统计学意义(P=0.023)。结论:ECG及超声心动图阳性结果与缺血相关责任血管具有一定预测价值,但阴性不能排除缺血性心脏病。

[ABSTRACT]Objective: To investigate the relationship between electrocardiogram (ECG) and echocardiography in patients with ischemic heart disease. Methods: 2 568 patients with ischemic heart disease underwent coronary angiography, and the results were evaluated by angiography. The relationship between ECG and echocardiography was analyzed. Results: The incidence of coronary artery disease was high, and the incidence rate was 73.93%. ECG and echocardiography were compared with that of single coronary artery disease group, double branch lesion group and three branch lesion group. The positive change of ECG was significantly higher than that of the right coronary artery(P=0.539), but no significant difference was statistically significant(P=0.023). Conclusions: The positive results of ECG and echocardiography have some predictive value, but it can not rule out the ischemic heart disease.
