采用心尖搏动图(ACG)和多普勒超声心动图检查50例老年冠心病患者的左室功能,并与32的健康老年人比较。结果冠心病患者均有程度不同的舒张功能异常。主要表现为多普勒二尖瓣口舒张早期峰值速度(E)降低、舒张晚期峰值速度(A)增加,A/E比值增大;ACG的A波及心房音S_4振幅增大。两种方法检测结果相关性较好。
Left ventricular function was measured in 50 elderly patients with coronary heart disease using apical beating chart (ACG) and Doppler echocardiography, and compared with 32 healthy controls. Results Patients with coronary heart disease have different degrees of diastolic dysfunction. The main manifestations of Doppler mitral valve early diastolic peak velocity (E) decreased peak late diastolic velocity (A) increased, A / E ratio increased; ACG A and atrial stenosis amplitude increased. The correlation between the two methods test results is good.
