摘　　要：对70例经选择性冠状动脉（冠脉）造影确诊的冠心病患者作经颇多普勒超声检查，观察主要大中型脑动脉的搏动指数（PI）、阻力指数（RI）和狭窄情况，并与30例正常人进行对比。结果表明，冠心病患者各脑动脉的PI和RI均较正常人明显增加（P＜0．01），脑动脉狭窄发生率明显高于正常人（P＜0.01）。随着冠脉病变支数的增多，脑动脉的PI和RI相应增大（P＜0．05），脑动脉狭窄的例数有增多的趋势。Transcranial Doppler ultrasonography was performed in 70 coronary artery disease (CAD) patients who had been consecutively exandned by coronary angiography and 30 normal persons. Pulsatility index(PI),resistant index (RI) and the rate of stenosis of main large ndddle cerebral arteries were obtained. The results showed that PI and Rl of all cerebral arteries were sighficant increasing in CAD patients (P <0.01). The rates of stenosis of cerebral arteries in CAD patients were more high than normal control (P <0.01). As coronary atherosclerosis progressed,the rates of stenosis of cerebral arteries were also increased.
