Key result
Work experience of 10 to 20 years in oil production was associated with unfavorable changes in heart rate variability, including a 2.2-fold decline in pNN50 and increases in SDANN and SDNN.
Why the study?
Reduced HRV is linked to elevated cardiovascular mortality, and oil production workers face occupational hazards that negatively impact the cardiovascular system.
Does exposure to occupational hazards in oil production alter heart rate variability in workers?
Observational
Does exposure to occupational hazards in oil production alter heart rate variability in workers?
Effect estimate: decline of pNN50 by 2.2 times, increase in SDANN by 1.4 times, increase in SDNN by 1.3 times
Long-term exposure to oil production hazards is associated with unfavorable changes in heart rate variability, highlighting the need for primary cardiovascular prevention in this workforce.
May warrant HRV monitoring in mid-career oil workers; hypothesis-generating for occupational CV prevention.
Reduced heart rate variability (HRV) is associated with the elevated mortality rate in patients with cardiovascular disease. Risk factors, in terms of the negative impact on the cardiovascular system of workers of oil production include noise, vibration, the severity of the labor process, climate, lighting, and various chemicals presenting in the working area (the total of various hydrocarbons, including aromatic hydrocarbons, disulfide sulfur). HRV indices were recorded daily by Holter monitoring. Employees with the work experience at oil production from 10 to 20 years were established to have a statistically significant increase in tone of the sympathetic nervous system, characterized by the decline ofpNN50 by 2.2 times and the increase of the vagal tone, characterized by an increase in SDANN by 1.4 times and SDNN - by 1.3 times. A significant dependence of the probability of the increasing of the tone of the sympathetic nervous system from work experience was established. Thus, the impact of hazards of oil-producing enterprise is associated with prognostically unfavorable changes in HRV. These changes may exacerbate hypertension in employees, which requires measures for the primary prevention of cardiovascular diseases.

Носов et al. (2019) conducted an observational in Cardiac abnormalities. Work experience at oil production was evaluated on Heart rate variability (HRV) indices (decline of pNN50 by 2.2 times, increase in SDANN by 1.4 times, increase in SDNN by 1.3 times). Work experience of 10 to 20 years in oil production was associated with unfavorable changes in heart rate variability, including a 2.2-fold decline in pNN50 and increases in SDANN and SDNN.
