摘要
用Mx3型脉象仪描记68例冠心病患者(内有36例急性心肌梗塞患者)桡动脉脉象;用QFM1000型多普勒超声血流仪检测了其中20例的颈动脉桡动脉的血流量,流速、管径、搏动范围。计算得出零压周围阻力,血管容积弹性模数。与20例同年龄、除患有动脉硬化外,无其他心脑血管疾患者相对照,结果表明,慢性冠状动脉供血不足的患者与对照组比较,颈动脉血流量减少较桡动脉明显,而颈动脉、桡动脉零压周围阻力均增加,似表明这种改变是心源性的。急性心肌梗塞患者的脉象图改变主要是主波幅降低及全曲线总面积减少。
In 68 cases of coronary heart disease,36 pertaining to acutemyocardial infarctions,the sphygmographic study of radial arteries per-formed with Mx3 sphygmographic apparatus.20 among the 68 cases werealso examined with QFM system 1000 Doppler ultrasonic rheogram,thecarotid and radial arteries examined and the blood volume,velocity ofblood flow,diameters of arteries and their scope of fluctuations can beread out directly,and the zero pressure resistance and modulus of arterialvolume elasticity calculated out.The control group consists of 20 cases of the same age group without cardio-cerebral vascular diseases exceptarteriosclerosis.In chronic coronary insufficiency the reduced blood volumeis more apparent in carotid arteries than in radial arteries,and theincrease of zero pressure resistance is evident in both arteries.Thisdifference probably indicated its cardiac origin,In acute myocardial infar-ction the sphygmographic changes are essentially the diminished amplitudeof the main wave and the area enveloped in the entire tracing.Thesemanifestations of dynamics of peripheral arterial circulations are comple-mentary to each other from the sphygmographic and the Doppler ultra-sonic rheographic examinations.
