Introduction. The relevance of the study of cardiovascular diseases (CVD) as a production-related pathology in workers at industrial enterprises is due to the presence in the technological process of production factors (noise, general vibration, microclimate, severity of labor, chemical factors), potentially capable of provoking the development of CVD.The aim of the study was to assess respiratory and metabolic disorders, which are risk factors for CVD, in workers exposed to dust, chlorine and hydrogen chloride.Materials and methods. 139 patients working under the influence of dust, chlorine and hydrogen chloride were examined. Among the surveyed 74 women and 65 men. The comparison group (45 people) consisted of 20 women and 25 men who were not exposed to harmful factors of production during their working life.Results. In the group of workers exposed to occupational exposure to dust, chlorine and hydrochloride vapors, it was revealed that the proportion of workers with arterial hypertension was 33.3%, in the comparison group–17.6%, p<0.05 (RR 1.99; 95% CI 1.01–3.93; EF=47%; the degree of professional conditioning is average). The volume of forced exhalation per 1 second (FEV1) in the observation group was 3.18±0.14 l, and in the comparison group–4.1±0.20 l (p<0.001). The level of total cholesterol in the observation group was 5.72±0.13 mmol / l, and in the comparison group–5.16±0.23 mmol / l (p<0.05). The observation group showed a decrease in HDL (1.35±0.04 mmol / l vs. 1.64±0.10 mmol / l in the comparison group, p<0.05) and an increase in triglycerides (2.3±0.17 mmol/l versus 1.51±0.16 mmol/l in the comparison group, p<0.05).Conclusions. In the group of workers exposed to professional dust, chlorine and hydrochloride vapors, a decrease in the speed parameters of the external respiratory function, the development of proatherogenic metabolic disorders, and an increase in laboratory indicators of inflammation were revealed. These changes can lead to early manifestation of cardiovascular and respiratory pathology in this category of workers.
