| Popis: | The purpose of the study was to assess work-related diseases of blood circulation among workers occupationally exposed to noise in mineral extraction. Material and methods. Working conditions, health status of 1481 workers of leading occupations of oil and ore minerals extraction along with the assessment of cardio-vascular system functional state according to electrocardiography, eye fundus vessels, systemic microhemodynamics and blood microcirculation of bulbar conjunctiva have been studied. Results and discussion. Workers of these occupations are exposed to a complex of work environment and work process factors with occupational noise as a priority one. Blood circulation diseases are detected two times more frequently among workers than in the control group. Arterial hypertension frequency increases with age and work experience; a reliable increase is observed among individuals with work experience of 11-15 years and more than 15 years as compared to the group of workers with 6-10-year work experience and less than 5 years. On electrocardiographic examination, changes in the heart have been revealed in 54.2 % of workers engaged in ore extraction and 42.9 % of workers of oil extraction. Cerebrovascular diseases in most workers have been diagnosed along with arterial hypertension and atherosclerotic processes confirmed by changes in the eye fundus vessels. Thus, the elevated prevalence and an increase in arterial hypertension frequency due to work experience do not exclude potential impact of hazardous working conditions on its formation. The significant role of working conditions for arterial hypertension development has been established among operators of overhaul and underground repair of wells, drift miners, machinists of loading and delivery machines, aggregates and excavators. This is the foundation for the development of measures for creating safe working conditions and prevention of blood circulation diseases. |
