For the first time on the Fergana Valley model, prognostic markers of the risk of thrombotic complications in COVID-19 patients with type 2 diabetes were studied. It was found that the level of glycemia, the concentration of proinflammatory cytokines IL-6, ferritin and CRP, and the marker of thrombus formation - d dimer, have a prognostic significance, with the maximum prognostic significance of the concentration of CRP. The prognostic significance of ultrasound in the aspect of thrombosis of the branches of the PA in patients with COVID-19 against the background of type 2 diabetes was established. Predictor markers are mean PA pressure, LV myocardial mass index, signs of increased intraventricular pressure in the RV, and evidence of peripheral venous thrombosis.
