Left ventricular(LV) diastolic dysfunction with preserved LV systolic function is common among patients with hypertension, especially with LV hypertrophy. Doppler echocardiography is one of the most useful clinical tools for the evaluation of diastolic function. Mitral inflow and pulmonary venous flow velocities are used not only for the assessment of diastolic function but also for predicting prognosis. Recently, tissue Doppler echocardiography has been also applied to evaluate diastolic function. Accurate assessment of diastolic function has been demonstrated by measuring both mitral annulus and mitral inflow velocity. In this article, We review the diagnosis of diastolic dysfunction by Doppler echocardiography using mitral inflow velocity, pulmonary venous flow velocity and mitral annulus velocity measured by tissue Doppler imaging.
左心室收缩功能正常但舒张功能障碍在高血压患者中很常见，尤其是伴有左心室肥厚的患者。多普勒超声心动图是评估舒张功能最有用的临床工具之一。二尖瓣流入血流和肺静脉血流速度不仅用于评估舒张功能，还用于预测预后。近年来，组织多普勒超声心动图也被用于评估舒张功能。通过测量二尖瓣环和二尖瓣流入血流速度，已证实可准确评估舒张功能。在本文中，我们回顾了利用组织多普勒成像测量的二尖瓣流入血流速度、肺静脉血流速度和二尖瓣环速度，通过多普勒超声心动图诊断舒张功能障碍的方法。
