Abstract:
Currently, there is no doubt about the importance of the role of impaired endothelial functional state in
the development of vascular pathology in a number of diseases, including rheumatic. With the advent and largescale
spread of a new coronavirus infection (COVID-19), a high rate of patient’s hospitalizations with
ankylosing spondyloarthritis (AS) and the development of extrapulmonary complications, such as myocardial
injuries, kidney damage and vascular thromboembolism, were noted. The development of this phenomenon
confirms the connection with pronounced endothelial dysfunction and its damage. This article presents the
results of evaluation of endothelial dysfunction in AS patients undergoing COVID-19.
