Application of high resolution sonography in evaluating vascular endothelial function in patients with early-stage diabetic patients / 中华老年医学杂志

ABSTRACT

Objective To evaluate the endothelial function in diabetic patients by high resolution sonography. Methods The intima-media thicknesses (IMT) of the bilateral carotid artery, femoral artery and the iliac artery of 22 elderly patients and 142 non-elderly patients with diabetes mellitus (DM) and 20 elderly and 20 non-elderly healthy persons were measured. The changes of the diameter of brachial artery were determined by measuring the diameter of brachial artery during reactive hyperemia and after sublingual nitroglycerin. Results The increased percentage of the brachial artery diameter under reactive hyperemia was significantly lower in elderly patients with DM (10. 03?6. 39)% than that in the elderly healthy control (15. 87?4. 79)% (P 0. 05). The IMT in elderly patients with early-stage DM incrassated significantly(P
