应用多普勒超声心动图二尖瓣舒张期血流速度积分(FVi)及前(3/1)、(2/1)时间充盈分数(1/3TFF、(1/2)TFF)法,检测46例非胰岛素依赖型糖尿病(NIDDM)和30例正常查体者左室舒张功能。结果:NIDDM全组FVI减低,但无显著性差异,前(1/3)TFF相差非常显著;(1/2)TFF相差显著,NIDDM伴合并症组FVI、(1/2)TFF相差显著、(1/3)TFF相差非常显著,无合并症组前(1/3)TFF相差显著、FVI及(1/2)TFF无显著性差异。结论:NIDDM伴合并症组心肌舒张功能严重受损,应视为糖尿病性心肌病,无合并症组仅早期主动舒张功能减退,心肌代偿好,可视为临床前期心肌损害。多普勒超声心动图充盈分数法可用于糖尿病友室舒张功能的评价及糖尿病性心肌病的筛选。
Application of Doppler echocardiography mitral diastolic flow velocity integral (FVi) and before (3/1), (2/1) time filling fraction (1 / 3TFF, (1/2) TFF) 46 cases of non-insulin-dependent diabetes mellitus (NIDDM) and 30 cases of normal physical examination of left ventricular diastolic function. Results: The FVI and (1/2) TFF in the NIDDM group were significantly lower than those in the NIDDM group (P <0.05), but there was no significant difference between the two groups (1/3) TFF, the difference between before and after (1/3) TFF was not significant, FVI and (1/2) TFF had no significant difference. Conclusions: Myocardial diastolic function is severely impaired in NIDDM with comorbid syndrome and should be regarded as diabetic cardiomyopathy. Only the early active diastolic dysfunction and compensatory myocardium in non-comorbid comorbid group may be regarded as preclinical myocardial damage. Doppler echocardiography filling fraction method can be used to evaluate the diastolic function of diabetic compartment and diabetic cardiomyopathy screening.
