多普勒超声心动图观测左心结构及舒张功能对高血压早期诊断的意义

Significance of observation of left ventricular sreucturc and diastole function by doppler echocardiogram in rarly diagnosis of hypertention

目的 观测高血压病患者左室舒张功能及结构指标的变化。方法 采有多普勒超声心动图检测患病组与正常对照组的左室结构与左室舒张功能:高血压患者左房内径,左室内径,室壁厚度,左室心肌重量及舒张功能。结果 高血压组左房增大发生率为79％,左房内径与对照组比较有显著差异(P<0.01)。舒张功能指标与对照组比较亦有显著差异(P<0.01)。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。

AIM To observe the changes of the index of left ventricular structure and diastole function in hypertention patients. METHOD Using Doppler echocardiogram to measure the ventricular structure and diastole function in diseased group and normal control group as well asto observe the diameter of left antrum and left ventricle, thickness of ventricular wall, weight of left ventricular myocardium and diastole function in hypertention patients. RESULTS The incidence of enlargement of left antrum was 79%. The difference of the diameter of left antrum between the hypertention group and control group was significant ( P < 0. 01) . There was significant difference of the index of diastole funtion between the hypertention group and control group (P < 0. 01 ). 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.
