超声心动图检查高血压病对左心室构型和舒张功能的影响

目的探讨高血压病患左心室构型及舒张功能的变化。方法应用超声心动图检测51例高血压患及39例对照组的左心室结构，包括左室舒张期内径(LVDd)，室间隔厚度(IVST)，左室后壁厚度(LVPWT)，左房内径(LAD)，左室体质量(LVM)以及左室舒张功能指标，包括左室等容舒张时间(IVRT)，二尖瓣口血流频谱E峰最大流速(E)峰，A峰最大流速(A)峰值，E、A流速比E／A，E、A峰充盈分数比(FFE／FFA)，肺V血流频谱收缩期S波最大流速(S)，舒张期D波最大流速(D)，S、D峰值流速比(S／D)。结果左心室结构测值中室间隔厚度及左室质量两组参数具显差异，舒张功能指标中两组参数间均具显差异。结论高血压病早期构型已发生变化，且左室舒张功能趋于减退。

Ultrasonographic Evaluation of Hypertension Influence on Left Ventricular Remodeling and Diastolic Function

Objective To assess ventricular diastol ic function in patients with essential hypertension using Doppler echocardiograp hy. Methods Fifty-one patients with essential hypertension a nd thirty-nine normal controls were examined with echocardiography.Parameters w ere easured including left ventricular and diastolic function indices. Results There was significant difference in left ventricu lar diastolic function betweent the two groups including parameters of left vent ricular posterior wall thinkness(LVPWT)and interventriculare septum thinkness(IV ST). Conclusions Left ventricular remodeling is present in ess ential hypertension patients at early stage and is accompanied with left ventric ular diastolic function exacerbation.
