INTRODUCTION. Human labor activity in the Arctic takes place in severe climatic conditions associated with cooling, atmospheric pressure drops, high humidity, photoperiodicity, low oxygen content in the air. Endothelial dysfunction is an early pathophysiological sign and an independent predictor of poor prognosis in most cardiovascular diseases. OBJECTIVE.Тo analyze the dynamics of the level of metalloproteinase-9 and thrombin activity as predictors of the development of atherosclerosis in sailors during a translatitudinal sea voyage in the Arctic. MATERIALS AND METHODS. A prospective clinical and laboratory study of crew members was performed during the integrated marine research expedition “Transarctic-2019”. A clinical and laboratory study of the level of metalloprotease-9 (enzyme-linked immunosorbent assay), coagulation analysis of the parameters of the thrombin generation test, as well as ultrasonic dopplerography of the thickness of the intima-media complex were carried out. Statistical data processing was carried out using the methods of descriptive and analytical statistics in the StataCorp Stata 14.2 program. The study protocol was approved by the local ethical committee of the SSMU (protocol No. 03/5 dated May 27, 2015) and supported by the state task reg. No. NIOKTR 121030300111-7. RESULTS. A statistically significant increase in the level of MMP-9 in sailors after the expedition was noted, the relationship between the level of MMP-9, indicators of the thrombin generation test (lag time, min (p=0.0190), tPeak (p=0.0177), Peak (p= 0.0217) and KIM thickening. DISCUSSION. MMP-9 levels may be a predictor of early atherosclerosis and atherosclerotic plaque instability, as well as a risk factor for future adverse cardiovascular events. The relationship of MMP-9 with the kinetics of thrombin (one of the regulators of the antithrombotic state of the endothelium) during a translatitudinal voyage in sailors indicates the formation of readiness for prothrombotic events. CONCLUSION. Thus, in Arctic conditions, ...
