Popis: AIM The increased incidence of atherosclerotic macrovascular disease in type 2 diabetic patients is associated both with diabetes specific factors and coexisting classic cardiovascular risk factors as components of the metabolic syndrome. The aim of this study was to investigate the association between the duration of diabetes and early functional and morphological markers of atherosclerosis compared to the impact of coexisting cardiovascular risk factors such as hypertension, dyslipoproteinemia and cigarette smoking. METHODS 63 type 2 diabetic patients and 25 non-diabetic control subjects were investigated. Lumen diameter of the brachial artery was measured by high-resolution ultrasound at rest and after 5-min suprasystolic arterial compression. Endothelium-independent dilatation of the brachial artery was measured 4 min after sublingual administration of 400 mug of glycerol trinitrate (GTN). Percentage change of arterial lumen diameter during reactive hyperemia (FMD%) and after GTN administration (GTN%) relative to the baseline measurements were calculated. The intima-media thickness (IMT) of the common carotid artery was measured bilaterally and averages were calculated. RESULTS FMD% (3.8+/-0.8% vs. 6.9+/-0.9%; p
