超声心动图和冠状动脉造影对冠心病诊断的比较观察

The relative observation of Echocardiogram and coronary arteriongraphy for the diagnosis of coronary heart disease

目的研究超声诊断冠心病的意义及应用价值。方法对88例临床拟诊为冠心病的患者行超声心动图检查,观察有无节段性室壁运动异常及其部位;对上述病人行冠脉造影检查,观察三支冠脉有无病变,狭窄及狭窄程度,狭窄大于50%则可诊断为冠心病。结果超声对冠心病的诊断符合率93.1%,定位准确率为82.9%,与冠脉造影相比没有显著性差异,二者有较好的一致性。超声表现特征为:节段性室壁运动减弱、消失或矛盾运动。结论对临床怀疑为冠心病的病人,超声心动图是一项首要的无创检查方法。

Objective To study the significance and application value of ultrasound in the diagnosis of coronary heart disease. Methods We treated clinical para - diagnosis coronary heart disease of 88 patients with echocardiography, to observe if there are regional wall motion abnormalities and their locations ; for the above patients, treated with coronary arteriongraphy coronary to observe whether there are pathological changes, stenosis and the degree of stenosis in the three coronary arteries, if the stenosis exceed 50% ,we can definite the coronary heart disease. Results The diagnose accordance rate of ultrasound to coronary heart disease is 93.1%, localization accurate rate is 82.9%, compared with coronary arteriongraphy there is no significant difference, the two have better con- sistency . The characteristic of ultrasonic manifestation ： regional wall motion abnormalities hypomotility, disappear or paradoxical motion. Conclusion To clinical doubt patients of coronary heart disease, Echocardiogram is the first method for non - invasive examination.
