The systolic and diastolic left-ventricular myocardium function was assessed by Doppler echocardiography in patients with hypertension. The study was carried out on 40 patients (26 men and 14 women) aged 21-50 years (mean 45 years) with essential hypertension, stage II according to WHO classification. The control group comprised 20 healthy subjects aged 19-48 years (mean 43 years). In patients with hypertension, as compared to controls, the Doppler curve of aortic flow showed an increased maximal and mean velocity of flow, the ejection time was shortened, and the ejection time to acceleration time index was decreased. The Doppler curve of the mitral flow in the patients showed reduced maximal velocity of early diastolic flow, increased velocity of maximal end-diastolic flow, decreased fraction of rapid left-ventricular filling, and lower ration of maximal early diastolic to end-diastolic flow. Doppler echocardiography is a useful method for assessment of left-ventricular myocardium functions in hypertension.
采用多普勒超声心动图评估高血压患者左心室心肌的收缩和舒张功能。该研究对40例年龄在21至50岁（平均45岁）的原发性高血压患者进行，根据世界卫生组织分类为II期。对照组包括20名年龄在19至48岁（平均43岁）的健康受试者。与对照组相比，高血压患者的主动脉血流多普勒曲线显示最大和平均血流速度增加，射血时间缩短，射血时间与加速时间指数降低。患者二尖瓣血流的多普勒曲线显示舒张早期血流最大速度降低，舒张末期血流最大速度增加，左心室快速充盈分数降低，舒张早期最大血流与舒张末期最大血流比值降低。多普勒超声心动图是评估高血压患者左心室心肌功能的一种有用方法。
