Comorbidity in patients with cardiovascular disease who underwent a new coronavirus infection


According to Rosstat data for 2020, the total mortality in Russia against the background of the COVID‑19 pandemic increased by 19.2%. In parallel, there was also an increase in mortality from cardiovascular diseases (CVD) by 11.8%. Negative dynamics can be caused by a number of organizational and medical reasons. Among the first, it is worth noting a decrease in the volume of care provided to cardiological patients, due to the periodic conversion of hospitals for the treatment of patients with COVID‑19. Unpredictable stoppage and delays in the planned treatment of CVD can worsen the patient’s prognosis in a short time or lead to cardiological pathology decompensation. Voluntary patients refusals from hospitalization due to the unfavorable epidemiological situation and fear of intrahospital infection with COVID‑19 could also limit the availability of medical care. However, the increase in mortality from CVD is not only due to the difficulties of routing cardiological patients, but also the nature of the disease itself. A new coronavirus infection is often both the main cause of death and a serious concomitant disease that significantly affects the development of lethal complications with existing chronic pathology.
