摘　　要：目的　探讨应用多普勒超声检测二尖瓣及肺静脉血流频谱对评估充盈限制型左室舒张功能不全的价值。方法　应用多普勒超声技术 ,对 10例充盈限制型左室舒张功能不全的冠心病患者和 46例正常对照者的二尖瓣及肺静脉血流频谱进行检测 ,并与常规超声心动图检查结果作对照分析。结果　充盈限制 (RF)组与对照组比较 ,表现为二尖瓣E峰、A峰速度比 (EV AV) >2 ,肺静脉收缩期、舒张期速度比 (VS VD) <1,肺静脉收缩分数 (SF) <0 .5 0 (P <0 .0 5 ) ,左房、左室及左室重量指数 (LVMI)增大 (P <0 .0 1) ,左室射血分数 (LVEF)下降 (P <0 .0 1) ,左房压力增高 (P <0 .0 1)。结论　结合常规超声心动图结果和临床症状 。Objective To investigate the value of Doppler echocardiography appilcation in assessing restrictive filling left ventricular diastolic function patients by measuring the spectra of mitral flow and pulmonary venous flow.Methods 10 coronary artery disease (CAD)patients which were restrictive filling left ventricular diastolic dysfunction and 46 normal control subjects mitral flow and pulmoary venous flow are measured,and corralation between Doppler spectra and conventional echocardiography measurements was analyzed.Results To compare with normal control subuects, restrictive filling (group RF):EV/AV>2,S/D<1,SF<0.50( p <0.05～0.01),accompanied with enlargemants of left atrium and ventricle, increased LVNI and decreased LVEF( P <0.01),elevated left atrial pressure(LAP)( p <0.01).Conclusion In carrying out a comprehensive analysis of Doppler echocardiographic measurements has fairly diagnositic value in restrictive filling left ventricular diastolic dysfunction, coupled with results of conventional echocardiography and clinical symptoms.
