摘要:
目的 探讨二尖瓣口血流频谱和瓣环的组织多普勒频谱与左室平均舒张压的关系。 方法 将79例患者分为正常组、早期舒张功能不全组和假性正常化组，测量其二尖瓣口的血流频谱（E、A、E/A比值和E峰减速时间DT）、二尖瓣环的组织多普勒频谱（s、e、a和e/a比值）、肺静脉血流频谱（PVs、PVd）及E/e。 结果 与假性正常化组的E/e比值比较，显著高于其它两组（P<0.01）；与假性正常化组的左室平均舒张压（mLVDP）为（12.6±2.8 ）mmHg比较，显著高于早期舒张功能不全组的左室平均舒张压（6.8±1.7） mmHg（P<0.01），E/e比值与左室平均舒张压（mLVDP）呈较好的相关性（r＝0.83，P<0.01）。 结论 E/e比值增高对评估mLVDP升高意义较大。
Abstract:
AIM To evaluate the value of Doppler echocardiography and tissue Doppler imaging (DTI) in assessing left ventricular diastolic pressure. METHODS Seventynine patients were divided into three groups: the normal group, the impaired relaxation group and the pseudonormal group. The transmitral flow velocity, mitral annular motion velocity and pulmonary venous flow velocity were measured. RESULTS The E/e ratio was related well to the mean left ventricular diastolic pressure (mLVDP). CONCLUSION The E/e ratio is of high valuable in estimating the elevated mLVDP.
