超声多普勒检测糖尿病左室舒张功能的探讨

目的 探讨无创评价糖尿病左室舒张功能。方法 对60例正常人和128例糖尿病患分三个年龄段比较超声多普勒检测二尖瓣口血流早期充盈峰（E）和舒张晚期充盈峰（A）的值。以及左室等容舒张时间（IVRT）值，分析糖尿病患血流参数之异常。结果 糖尿病患E/A值降低。IVRT值延长。结论 糖尿病患左室舒张功能减弱。多普勒检查能无创的评价糖尿病患的左室舒张功能。

Study of left ventricular diastolic function in patients with diabetes mellitus by Doppler ul-trasound

Purpose To estimate the left ventricular diastolic function of patients with diabetes mellitus harmelessly. Methods One hundred and twenty - eight DM patients and Sixty nromal subjects were divided into three groups according to the age. The measurements included the maximal velocity, time - velocity integral of the early filling, isovolumentrie contraction time and their ratio. Deserve the abnormal of flow parmeter of the patients with diabets mellitus. Results Comparion with normal subjects E/A decreased and IVRT increased in groups of diabetes mellitus. Conclusion there is impairment of left ventricular diastolic funciton in patients with diabetes millilus. Doppler echocardiography can estimate left ventricular diastolic function of patients with diabetes mellitus.
