应用脉冲多普勒超声心动图对５５例正常人和７０例高血压患者进行左室舒张功能评价的结果示高血压患者（Ｈ）组和正常人的二尖瓣血流速度同样受年龄影响，但程度不同；高血压患者心室舒张功能异常早于收缩功能异常，异常舒张功能的二尖瓣血流频谱表现各异，高血压病Ｈ１（Ａ／Ｅ≥１）亚组为典型改变，而Ｈ２（Ａ／Ｅ＜１）亚组（３３％，２２／７０）却呈“正常化”。认为不能仅以二尖瓣血流频谱尤其Ａ／Ｅ值作为准确评价高血压患者心室舒张功能的依据。
Using pulsed Doppler echocardiography to evaluate left ventricular diastolic function in 55 normal subjects and 70 hypertensive patients showed that mitral flow velocities in hypertensive patients (H) and normal subjects were also affected by age, However, the degree of ventricular diastolic dysfunction was earlier than that of systolic dysfunction in hypertensive patients, and the mitral flow spectrum of abnormal diastolic function was different. The subtypes of hypertensive H1 (A / E≥1) (A / E <1) subgroup (33%, 22/70) showed “normalization”. It is not believed that only the mitral flow spectrum, especially the A / E value, should be used as the basis for accurate assessment of ventricular diastolic function in hypertensive patients.
