Results: A significant relationship was found between the job demand-control model and cardiovascular risk factors. In terms of chisquared test results, the highest value was assessed for heart rate (Chi2 = 145.078). The corresponding results for smoking and BMI were Chi2 = 85.652 and Chi2 = 30.941, respectively. Subsequently, Eta result for total cholesterol was 0.469, followed by hypertension equaling 0.684. Moreover, there was a significant difference between cardiovascular risk factors and job demand-control profiles among different working groups including the operational group, repairing group and servicing group. Conclusion: Job control and demand are significantly related to heart disease risk factors including hypertension, hyperlipidemia, and cigarette smoking.RESULTS: The development and progression of CVD in petrochemical production workers affects a complex working environment hazards and the labor process, corresponding, according to R2.2.2006-05, classes, working conditions 3.1-3.3 Labor intensity. The most common form of cardiovascular nosology was hypertonic disease (HD), identified in 46,9% of apparatchiks and 29,2% of fitters of instrumentation and automation. Determination of the relative risk etiological share of the working environment factors in the development of HD showed high degree of professional conditioning of the disease in a group of apparatchiks (RR=1,58, and EF=36,7%). Molecular genetic factor predisposing to the development of CVD, is the deletion of the GSTM1 gene. This genetic marker could be used as a predictor of individual risk criterion CVD.CONCLUSION: A comprehensive assessment of working conditions of workers of petrochemical plants showed that the priority factors of occupational risk for apparatchiks are air pollution of the working area with harmful substances (class 3.1-3.2), noise (class 3.1) and labor intensity (class 3.1). It has been established that in the formation of cardiovascular diseases under the influence of production factors, genetic factors can participate.
