Assessment of risk fors for the development of ischemic heart disease in workers of vibration-hazardous occupations

Introduction. Ischemic heart disease is common in workers exposed to vibration. In this regard, it is important to expand the search for cardiovascular risk factors among workers witih vibration-hazardous occupations for timely implementation of preventive measures aimed at reducing incidence, disability, and mortality from cardiovascular pathology. The aim of the study was to evaluate industrial and non-industrial risk factors for the development of ischemic heart disease in workers of vibration-hazardous occupations in the coal industry. Materials and methods. The study involved one hundred ninety four workers of the main occupations in the coal industry with vibration disease and 118 people without clinical signs of the disease. Clinical, instrumental, and laboratory investigations were conducted to identify ischemic heart disease and risk factors for its development. Results. Workers with vibration disease have been shown to have higher incidence of ischemic heart disease than the comparison group. The most significant non-occupational risk factors for ischemic heart disease in patients with vibration disease were revealed: arterial hypertension, abdominal obesity, burdened heredity, hypersthenic constitutional-morphological type according to Rees-Eysenck, increased levels of C-reactive protein, soluble fibrin-monomer complexes, hyperuricemia. The occupational risk factors for the development of ischemic heart disease in workers with vibration disease were determined: work experience in harmful labor conditions of 25 years or more, the development of the second degree of vibration disease. Limitations. The conducted study is limited to the number of workers exposed to vibration who were examined at the Federal State Budgetary Scientific Institution “Research Institute for Complex Problems of Hygiene and Occupational Diseases”. Conclusion. The most significant risk factors for the development of ischemic heart disease in workers of the main occupations in the coal industry who are exposed to vibration have been identified. During the prophylactic medical examination of patients with vibration disease, it is necessary to arrangement risk groups for the development of ischemic heart disease and elaborate measures for them aimed at correcting modifiable cardiovascular risk factors.
