Abstract
Mine-explosive trauma (MET) is the most common trauma type and one of the main disability causes of the able-bodied contingent. Among the mechanisms of the cardiovascular and cerebrovascular disorders development after MET, endothelial dysfunction (ED) plays an important role. The study aims - to assess the functional state of the microvessels and large arteries endothelium in men after a mine-explosive injury. Materials and methods: the functional state of the skin microvessels endothelium was determined using a two-channel laser Doppler flowmeter BLF-21D "Transonic Systems Inc" (USA) during the test with the creation of reactive hyperemia. The function of the large arteries endothelium was determined using the D.S. Celermajer test, with post-occlusion reactive hyperemia according to the generally accepted method on the Nemio XG device, SSA-580A (Toshiba) with a high-frequency linear sensor with a central frequency of 7 MHz. We examined men with mild MET (average age 37.7 ± 1.5 years). The control group was represented by 43 practically healthy men without MET (average age 41.8 ± 2.1 years). Results: dysfunction of the microvessels endothelium was found in most persons with MET (69.1%), compared to men without MET (41.9%). Dysfunction of the large vessels endothelium was found in 40.4% of examined persons with MET. Persons with MET have a combination of large and small vessel endothelial dysfunction in 23.4% of cases, at the same time persons without MET have a higher proportion of isolated microvessel endothelial dysfunction (34.9%). Conclusions: men with MET often have arterial endothelial dysfunction with microvascular endothelial dysfunction together, whereas men without MET have predominantly isolated microvascular endothelial dysfunction. ________________________________________________________________________________________ Keywords: mine-explosive injury; functional state of the endothelium; microcirculation.
