本文100例临床以心前区疼痛疑诊冠心病住院患者,经彩色多普勒超声心动图的二维超声观察和测量左冠状动脉(LCA)主干的结果与活动平板运动试验.并和其中37例冠脉造影进行对照。结果表明:(1)LCA 主干内经越小.硬化程度越高.P<0.01.(2)LCA硬化程度越高.运动试验阳性率亦越高 P<0.001、(3)冠脉内径越小,冠脉造影狭窄越重.运动试验阳性率亦越高。
This article 100 cases of clinically suspected patients with coronary heart disease in patients with suspected coronary artery disease, two-dimensional ultrasound color Doppler echocardiography and measurement of the left coronary artery (LCA) trunk and treadmill exercise test results and 37 Cases of coronary angiography control. The results showed that: (1) The smaller the LCA trunk was, the higher the sclerosis degree was. P <0.01. (2) The higher the degree of LCA sclerosis, the higher the positive rate of exercise test was P <0.001. (3) Coronary angiography stenosis heavier. The higher the positive rate of exercise test.
