应用彩色多普勒超声心动图检测１５３例Ⅱ型糖尿病患者和８０例正常人的左室结构及功能参数，显示糖尿病患者的室间隔和左室后壁均有不同程度的增厚，左室心肌重量增加，伴大血管病变者更为明显（Ｐ＜０．０１）；左室舒张功能异常，表现舒张早期二尖瓣口的血流峰值速度（ＰＶＥ）和二尖瓣前叶活动曲线的Ｅ峰至Ｆ点的斜率（ＭＥＦ）降低，左房收缩时二尖瓣口的血流峰值速度（ＰＶＡ）和ＰＶＡ与ＰＶＥ的比值升高（Ｐ＜０．０１）；收缩功能异常仅见于伴大血管病变的患者，表现每搏量（ＳＶ）、心排出量（ＣＯ）和射血分数（ＥＦ）减少（Ｐ＜０．０５）。提示糖尿病患者常见左室舒张功能损害，甚至见于无血管病变的患者，左室壁厚度和心肌重量均有不同程度的增加。彩色多普勒超声心动图检查有助于糖尿病心肌病的早期诊断。
The color Doppler echocardiography was used to detect the left ventricular structural and functional parameters in 153 patients with type 2 diabetes mellitus and 80 normal subjects. The results showed that left ventricular posterior wall and ventricular septum were thickening to varying degrees in diabetic patients, (P <0.01), diastolic dysfunction of left ventricle, peak velocity of mitral inflow in early diastole (PVE), and E The peak-to-F slope (MEF) decreased, the mitral valve peak velocity (PVA) and the ratio of PVA to PVE increased (P <0.01) in left atrial systole; systolic dysfunction was found only in patients with large Patients with vascular disease showed reduced stroke volume (SV), cardiac output (CO), and ejection fraction (EF) (P <0.05). Prompt common left ventricular diastolic dysfunction in patients with diabetes, and even seen in patients without vascular disease, left ventricular wall thickness and myocardial weight increased to varying degrees. Color Doppler echocardiography is helpful for the early diagnosis of diabetic cardiomyopathy.
