Background. The novel coronavirus disease 2019 (COVID-19), caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become an unprecedented challenge for the health care system and has taken a leading position among infectious diseases due to the rapid spread and development of complications from various body systems. The problem of cardiac comorbidity in COVID-19 has several aspects: the impact of concomitant cardiovascular diseases on the incidence of a new viral infection, its severity and risk of mortality, as well as possible side effects of a number of drugs traditionally used to treat certain types of cardiovascular diseases. SARS-CoV-2 is not only a pneumonia pathogen, but also causes serious systemic consequences. Patients with cardiovascular diseases and risk factors for cardiovascular complications, such as hypertension and coronary heart disease, are more exposed to fatal consequences of COVID-19. In addition, a significant proportion of patients develop COVID-associated myocardial injury, which significantly increases the risk of in-hospital mortality. The purpose of the study was to investigate the prognostic role of individual biomarkers in patients with COVID-19-associated pneumonia on the background of chronic coronary syndromes. Materials and methods. This study was defined as an open-label, non-randomized, controlled, comparative one in parallel groups. 124 patients with COVID-19-associated pneumonia were selected upon admission, including 92 participants with a history of chronic coronary syndromes. Results. The study showed that elevated levels of biomarkers such as proinflammatory cytokine interleukin-6, iron-storage protein ferritin, serum angiotensin-converting enzyme-2, ketone body beta-hydroxybutyric acid, and fibrin breakdown product D-dimer may be associated with a more severe course of pneumonia caused by COVID-19 infection. Thus, these biomarkers had good prognostic value in predicting severe disease and death in patients with chronic coronary syndromes during hospitalization. Conclusions. The study confirms that an increase in the level of proinflammatory biomarkers is a predictor for the development of a severe coronavirus infection.
