description The objective of this study was to evaluate the vasculomotor function of endothelium in patients with type 2 diabetes mellitus and assess the role of its functional state in the development of ischemic episodes. A total of 93 patients (52 men and 41 women) of the mean age of 58.3+-4.8 years were involved in the study. Group 1 comprised 47 patients with coronary heart disease (CHD) and type 2 diabetes, group 2 included 46 patients with CHD in the absence of disturbances of carbohydrate metabolism. Patients of the two groups were matched for age, gender, and major risk factors. Their comprehensive examination included 24 hour ECG monitoring, veloergometry, echocardiography, and reactive hyperemia test (ultrasound evaluation of endothelium-dependent dilation of the brachial artery). The patients of group 2 showed longer total duration of episodes of myocardial ischemia, the elevated number of painless (PMI) episodes, and greater maximum depression of ST-segment compared with CHD patients having no disturbances of carbohydrate metabolism. Correlation analysis demonstrated significant negative relationship between endothelial dysfunction, the number and duration of PMI episodes, and delay of pain syndrome with respect to ischemic depression of ST-segment in patients of group 1.
