SST2 and morphofunctional parameters of the left ventricle in patients with ischemic heart disease with chronic heart failure and previous COVID-19

Objective: to assess the concentration of the sST2 biomarker and its relationship with the morphological and functional parameters of the LV myocardium in patients with coronary artery disease and chronic heart failure (CHF) I-III functional class (FC), who had and did not have COVID-19. Material and methods. We examined 100 patients (66 males), median ( Me ) age 65 [63; 67] years, with stable coronary artery disease with CHF I-III FC (New York Heart Association), divided into 2 groups depending on the COVID-19. Along with the conventional clinical examination, the concentration of serum sST2 was determined by enzyme immunoassay.
