摘要
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。
The measurement of left coronary main trunk(LMT)by two dimensional echocardiography(2DE) of Colour Doppler and Treabmill Exercise Testing were performed in 100 patients with chest pain,who were diagnosed coronary heart disease,in whom 37 patients underwent coronary arteriography.The authers compared the result of 2DE,exercise testiong,with coronary arter- uiography and conclde: 1.The smaller LMT,the higher the degree of sclerosis of coronary artery will de.(P 0.01) 2.The heavier the degree of sclerosis of LMT,the higher the positive rate of exercise testing. 3.The smaller the LMT,a positive correlatiou exists LMT of 2DE,the heavier stricture of coronary arteriography,and the higher the positive rate of exercise testiug.
