Due to the extreme conditions of mobile work in the Arctic, study of the impact of expeditionary shift on cardiovascular health associated with factors of chronic social stress and the prevalence of ischemic heart disease is of particular importance. Objective. To study the prevalence of ischemic heart disease, major stressors in family and at work with and without this pathology in men working by expeditionary rotational method in the Arctic. Materials and methods. Men aged 25—54 working on expeditionary rotational shift mode at the EURAKOR industrial enterprise were the object of the study performed as part of the cardiac screening in 2022—2023. Representative sample included 750 persons, response to screening — 82.4%. The prevalence of ischemic heart disease (IHD) was studied using standardized epidemiological methods. Stressors in the family and at work were identified by the WHO MONICA-MOPSY questionnaire. Results. For men aged 25—54 who are engaged in expeditionary rotational shift work in the Arctic, the prevalence of IHD according to extended epidemiological criteria was 9.1%, «definite» IHD — 3.3%, «possible» IHD — 5.8%. In the absence of IHD, conflicts in the family and reduced opportunities for home relaxation were the main stressors. In the presence of IHD, a decrease in workload and responsibility at the workplace and an increase in the number of changes at work were the main stressors. Conclusion. Considering the established high prevalence of ischemic heart disease among economically active men engaged in mobile work at the oil and gas production facility, an analysis of determining several chronic social stress factors — family and work-related stressors that have a significant impact on expeditionary rotational shift work, both in the presence and absence of ischemic heart disease — revealed the need for more detailed screening of cardiovascular pathology in shift workers, including when entering employment in extreme Arctic conditions.
