Background. The problem of prevention and treatment of cerebrovascular diseases (CVD) in the world and in Ukraine takes a leading place in the decrease of the population mortality. Among the reasons of CVD development the atherosclerosis of vessels and hypertonic disease are mentioned the most often. However, less attention is paid to other etiological factors. The biological action of vibration on the human body can be the cause of development of the brain vessel pathology and, in our opinion, affects the formation of CVD.
Purpose. To study the prevalence, determination of risks of development of CVD and the etiological effect of vibration on their development in miners with vibration disease (VD), working in the open cast mines, caused by the effect of general vibrations in the post-contact period.
Materials and methods. 496 cards, designed for dynamic examination of patients with VD, caused by the effect of the general vibration on men-miners, residing in Dnipropetrovsk oblast (region) over the period of 1993—2012.
Results. The analysis of the statistical data shows that the vessel syndrome takes 64,5 % in the structure of VD and that 44,9 % patients suffer from cerebral vessel affection. Thus, among patients with the vessel pathology the cerebral angiodis-tonic syndrome has been is recorded in 70 % cases. Almost 5 % patients with VD have CVD due to the action of the general vibration. The analysis of the prevalence of the cerebrovascular diseases in the group of patients with VD allows to state that the latter is 3,36 times higher that indices for the adult male population, and the prevalence of the brain infarction is higher in 70 times. The risks of development of CVD in patients with VD prevail by several times as compared with such risks in the male population of Dnipropetrovsk oblast. In this, the probability of CVD development in the post-exposure period in patients with VD is 4,1 times higher than in the population.
Conclusion. The prevalence of CVD in patients with VD, due to the action of the general vibrations in the post-exposure period is several times higher than the same in the adult male population, and the brain infarction — by tens times. The risk of development of CVD in the post-exposure period in patients with VD as s result of the general vibrations is several times higher than in the population. All this demonstrate that the further study of peculiarities of VD development as a result of the action of the general vibration in the post-exposure period is rather actual and necessary.
