Lesions in the functional state of the cardiovascular system of patients with COVID-19 infection

Abstract

The coronavirus family has been known since the 20th century, but until the outbreak of severe acute respiratory syndrome coronavirus disease (COVID-19) and Middle East respiratory syndrome (MERS-CoV), they were not given appropriate clinical and epidemiological significance. Thus, the most severe respiratory diseases were caused by 3 beta coronaviruses, in particular SARS-CoV, SARS-CoV-2 and MERS-CoV. Although most patients with COVID-19 have a predominantly respiratory tract involvement, a certain cohort has a more severe course of the disease with the development of systemic involvement characterized by resistant fever, acute lung injury and severe acute respiratory syndrome, shock and subsequent multiorgan failure. The combination of diffuse intravascular coagulation with the formation of large-caliber vascular thrombosis is also associated with the development of multiple organ failure. Mortality rates from COVID-19 reach at least 10.0%.
