Atherosclerosis of peripheral arteries in patients with coronary artery disease and type 2 diabetes mellitus

Abstract

Aim. To study the features of atherosclerosis of peripheral arteries in patients with coronary artery disease (CAD) depending on the presence of type 2 diabetes mellitus (T2DM) and to identify factors associated with multifocal atherosclerosis. Materials and methods. The study included 140 patients (77 men and 63 women) with CAD (mean age 62.0 (56.0-66.0) years). The first group included 70 people with CAD and T2DM, and the second group included 70 patients with CAD without T2DM. All patients underwent duplex scanning of the carotid and lower limb arteries (LLA). Local vascular stiffness of the common carotid artery (CCA) was assessed by ultrasound scanning. The Peterson elasticity modulus, distensibility and strain of the CCA were determined. The ankle - brachial index (ABI) was measured by the Doppler method. Results and discussion. In the group of patients with T2D, there were statistically more patients with atherosclerotic plaques in both carotid arteries and LLA. Also among patients with T2DM the severity of stenosis of carotid arteries and LLA at all levels was significantly greater. Local carotid stiffness was higher in the first group of patients. The proportion of individuals with reduced ABI
