对３２例２型糖尿病患者作彩色多普勒超声检查，观察左中指固有动脉、足背动脉和心脏血流动力学改变，并与１９例非糖尿病者比较。发现糖尿病患者肢体远端动脉管壁增厚，走行迂曲，管腔轻度狭窄；血流频谱呈双相波，无舒张晚期频谱。糖尿病组的左房内径增大，二尖瓣舒张期频谱Ｅ峰降低，Ａ峰升高，Ｅ／Ａ比值减少。提示２型糖尿病未发生四肢缺血表现以前，已有上、下肢远端动脉硬化、狭窄和心脏舒张功能不全。
Color Doppler echocardiography was performed in 32 patients with type 2 diabetes mellitus. The left and middle third arteries, the dorsalis pedis artery and the hemodynamics were observed and compared with 19 non-diabetic patients. Diabetic patients found distal limb artery wall thickening, walking tortuous, mild stenosis; blood flow spectrum was biphasic, no late diastolic spectrum. Diastolic diameter of diastolic left atrium, mitral diastolic spectrum E peak decreased, A peak increased, E / A ratio decreased. Tip type 2 diabetes did not occur before the performance of limb ischemia, distal and distal lower limb atherosclerosis, stenosis and diastolic dysfunction.
