Cardiovascular risk in petrochemical workers

Abstract

Introduction. The high prevalence of diseases of the circulatory system of workers in various sectors of the economy, the lack of data on the effects of harmful production factors on the formation of cardiovascular diseases in petrochemical industry workers justify the importance of conducting special studies on these petrochemical complex plants with the aim of assessing cardiovascular risk with the subsequent development of preventive measures. Material and methods. The objects of the study were workers in the production of monomers (ethylene, propylene, ethylbenzene, isoprene, divinyl) of petrochemical enterprises. Hygienic studies of the working conditions of workers included an assessment of the factors of the working environment and the labor process using generally accepted methods. Comprehensive clinical examination of workers included periodic examinations (n = 2634) with calculation of total and relative cardiovascular risk using the SCORE system, using questionnaire data, a Reeder L questionnaire and an in-depth clinical diagnostic medical examination (n = 101) with the definition total cardiovascular risk. Results. The most significant occupational factors of the labor process for workers in the main profession - panmen were established to include the combination of a chemical factor with the occupational noise and labor intensity, with an overall assessment of working conditions 3.2. The class of working conditions of workers of the comparison group (locksmith in instrumentation and automation corresponds to the permissible). There were revealed a high prevalence of arterial hypertension and other factors of cardiovascular risk. A higher dependence of the arterial hypertension level on age and length of service in the group of panmen was established when compared to the mechanicians of instrumentation and automation. Using mathematical models of multiple regression, the likely dynamics of the level of arterial hypertension and the left ventricular myocardial mass index were calculated under the influence of increasing age and other risk predictors. Conclusion. The results of a clinical study showed workers with severe arterial hypertension, a high and very high risk of death from cardiovascular disease on the SCORE scale, a high and very high overall cardiovascular risk, signs of dyslipidemia, obesity, high stress levels to require close attention. It is important to timely diagnose lesions of target organs, to conduct rational prevention aimed at reducing risk factors. According to the results of the study, there were developed preventive measures aimed at reducing cardiovascular morbidity and cardiovascular risk, prolonging the longevity of workers in petrochemical industries.
