Introduction: After the COVID-19 pandemic, public healthcare has faced a new problem, the persistence of symptoms, the most significant of which is undue fatigue. The definition of coronavirus infection as an endothelial disease suggests a possible relationship between asthenic syndrome and endothelial dysfunction. Aim: to evaluate endothelial function in patients after COVID-19 before and after treatment with combination drug of ethylmethylhydroxyperidine succinate (EMHPS)/vitamin B6. Materials and Methods: A prospective study included 33 participants, 82% women and 18% men aged 22 to 68 years after COVID-19. There were two site visits made in the course of the study and a 4-week treatment course between the visits. Results: After the treatment, the index of endothelium-dependent vasodilation increased in women and decreased in men. The differences were statistically insignificant. The number of subjects with a normal level of endothelium-dependent vasodilation increased from 7 to 11 after the treatment. The index of vascular wall stiffness corresponded to the mean age of the examined participants and did not statistically change, although women tended to decrease stiffness and men to increase it. The initial level of nitric oxide was lower in women and statistically significantly increased after treatment, while it remained unchanged in men. Discission: The study confirms a prolonged course of the post-covid. We assume that the virus destroys endothelial cells.Endothelial dysfunction is known to be associated with an increased cardiovascular risk. Conclusion: The indicators of endothelial function changed in patients after treatment with the drug. It is necessary to perform endothelial function studies in more patients after COVID-19.
