Conclusions Higher ambulatory pulse pressure could induce the increase of left ventricular hypertrophy and decrease of left ventricular diastole function in the very elderly patients with hypertension .

结论动态脉压高的高龄高血压患者较动态脉压低者更易导致左室肥厚和左 室 舒张功能减退。

In the left ventricular outflow tract during diastole were similar echoes which returned to the aortic root during ventricular systole .

在 舒张期左 室流出道有相似的回声，而在收缩期，此回声又回到主动脉根部。

CONCLUSION The enlargement of left antrum and the reduction of left ventricular diastole function are the early cardiac zhanges of hypertention disease . Those changes occur before hypertrophy and enlargement of left ventrcle .

结论左房扩大及左 室 舒张功能减低为高血压病早期的心脏改变，发生在左室肥厚及左室扩大之前。

The function of left ventricular diastole weakened with age .

随年龄增长左 室 舒张功能减退；

When left diastole function in mitral flow pulse ( MFP ) is pseudo normal ' PW-DTI can actually assess the decrease of left ventricular diastole function .

以及左室舒张功能障碍患者二尖瓣血流频谱（MFP）表现为假正常时，DTI-PW在舒张功能障碍中的鉴别诊断价值，从而对左 室 舒张功能减低做出准确的评价。

Objective To evaluate the deformation features of left ventricular longitudinal myocardial contraction and diastole in coronary artery disease using the strain ( S ) and strain rate imaging ( SRI ) .
