摘　　要：目的:探讨应用多普勒超声心动图鉴别基础状态下左室充盈模式正常的无症状性Ⅱ型糖尿病患者左室舒张功能假性正常化发生率,以正确评价左室舒张功能障碍发病率。方法:对63例血糖控制良好的Ⅱ-型糖尿病患者进行多普勒超声心动图检测,应用二尖瓣血流充盈模式区分左心室舒张功能状态,应用Valsalva实验鉴别左室舒张功能假性正常化与左心室正常充盈状态。结果:左心室充盈状态正常34人(54%)、异常29人(46%),后者中左心室舒张功能损害18人(29%)、假性正常化11人(17%)。结论:在血糖控制良好的II型-糖尿病患者中左心室舒张功能障碍也常发生;对于在基础状态下二尖瓣血流充盈模式正常者,Valsalva动作可以鉴别出左室舒张功能假性正常化患者。Objective： To distinguish pseudo-normal diastolic function from normal filling pattern of left ventricular（LV） in patients with non-insulin dependent diabetes by using Doppler echocardiography.Methods： 63 diabetics with normal blood sugar levels after treatment accepted Doppler echocardiography.The filling patterns of mitral valvular blood flow was used to characterize diastolic physiology,and the Valsalva test was used to differentiate pseudo-normal from normal filling patterns of LV.Results： Normal filling patterns of LV occurred to 34 subjects（54%）,abnormal patterns appeared in 29 patients（46%）,among the later,18 patients（29%） had impaired relaxation and 11（17%） had pseudo-normal filling pattern.Conclusions： Diastolic dysfunction is often found in patients with non-insulin dependent diabetes,whose blood sugar levels were under control.The Valsalva test can distinguish pseudo-normal filling pattern of LV from normal filling pattern of atrioventricular valve in ordinary condition.
