Psychoemotional stress is a leading cardiovascular risk factor. Objective — to investigate the manifestations of arterial hypertension (AH) in young men having a stressful job. Subjects and methods. A total of 132 young men younger than 40 years of age who had been exposed to varying job-related stress (JS) for 1 to 3 years of work experience in law-enforcement agencies and regular field activities were examined. A control group consisted of age-matched men who did no field work. The classificational stressful job model developed by R. Karasek and T. Theorell (1981 and 1989) was used, according to which this activity is associated with higher responsibility, tight time, and danger on the one hand, and a limited capacity of personal decision making on the other. 24-hour blood pressure monitoring (24-h BPM) and rheoencephalography (REG) were applied. Results. Different types (persistent, isolated, office, and latent) of stress-related AH were significantly more frequently detected in those exposed to JS than in the controls whose routine work was unrelated to field activities. On days-off, all 24-h BPM abnormalities virtually levelled off. The signs of altered cerebral blood flow were also found in the young men who were exposed even to moderate occupational stress. Conclusion. In the young men upon even short-term exposure to JS, 24-h BPM shows abnormalities following the pattern seen in labile and persistent AH. The use 24-h BPM and REG is proposed for the regular prophylactic medical examinations of young men exposed to occupational stress in order to make a timely differential diagnosis of different types of stress-related AH and its associated cerebrovascular disorders.
