TO THE QUESTION OF DIAGNOSES OF ENDOTHELIAL DYSFUNCTION UNDER THE CONDITIONS OF THE TRANSPORTED FLIGHT IN THE ARCTIC

Abstract

The aim of the study was to assess the state of endothelial function in conditions of in the work, individual biochemical (homocysteine, folate, vitamin B12 levels) and functional (by peripheral arterial tonometry) markers of endothelial dysfunction during a marine trans-latitude voyage in the Arctic were studied. The design of the study is a prospective cohort nonrandomized study. The object of the study was practically healthy people - members of the Arctic scientific expedition and crew members of the marine scientific research vessel. The preliminary analysis of the obtained data allows to state that in healthy participants of short-term transhort maritime voyage in the Arctic abnormalities of endothelium-dependent vasodilation function were detected using the method of peripheral arterial tonometry on EndoPaT-2000 device with a test with active hyperemia and homocysteine exchange results, which indicates the presence of endothelial dysfunction. The unfavorable influence of high latitudes of the Arctic on the formation of endothelial dysfunction in healthy participants of the expedition and members of the research vessel crew was revealed.
