Annotation. In recent decades, the role of a chronic inflammatory process in the development of cardiovascular complications in patients with coronary artery disease and diabetes has been actively discussed. Target. study of markers of the vascular inflammatory process in patients with coronary artery disease in combination with type 2 diabetes. Identify a set of laboratory parameters that can become predictors of cardiovascular complications. Materials and methods. We examined 69 patients aged 60.3±9.8 years with coronary artery disease, stable exertional angina. Patients are divided into 2 groups. Group 1 - patients with IHD (n=30), Group 2 - IHD with type 2 diabetes (n=39). Results. The study of laboratory parameters of blood serum was carried out against the background of standard therapy before and after 12±2.4 months of observation. Initially, in the 2nd group of patients, a significant excess of the level of atherogenic parameters of the lipid profile (total cholesterol, VLDL, TG) and markers of inflammation (highly sensitive C-reactive protein, fibrinorgen ) was revealed compared to the 1st group. In IHD patients with DM in the 2nd group, more numerous and highly significant relationships were registered between atherogenic lipid fractions (LDL, TG), inflammatory markers (highly sensitive C-reactive protein , fibrinogen), endothelial dysfunction parameters (brachial artery diameter), glycated hemoglobin. The analysis of the results demonstrated the absence of positive significant dynamics of the lipid spectrum, the preservation of a prolonged response to the activation of the inflammatory reaction, the indicator of which was C-reactive protein, fibrinogen, and the presence of endothelial dysfunction in both groups of patients. The results of the study indicate the persistence of a sluggish inflammatory process in the endothelium, which is a provoking factor in the destabilization of the atherosclerotic process, both in the 1st and 2nd groups of patients. Conclusion. The increased risk of atherothrombosis in both groups requires more stringent control of the effectiveness of the therapy.
