title: [24-h profile of arterial pressure in hypertensive patients working in rotatory teams in conditions of Far North (Tyumen Region)].
abstract: OBJECTIVE
  To specify a 24-h profile of arterial pressure (AP) in hypertensive patients working in duty regime in the Far North (Tyumen Region).
  
  
  METHODS
  AP parameters were studied in 155 males aged 25-59 with hypertension of stage I, II who were employed for duty work in the Far North areas and 38 control patients with hypertension stage I, II living in a moderate climatic zone (Tyumen). The groups were comparable by gender, age, duration of hypertension, office systolic and diastolic AP (SAP and DAP). All the patients have undergone 24-h monitoring of AP with assessment of basic mean parameters.
  
  
  RESULTS
  The study group patients had scare symptoms and lower mean 24-h SAP, but high AP variability, high DAD as reflection of more significant structural changes of vessels and special functioning of the autonomic nervous system in the North. Mean 24-h AP showed more unfavourable changes in hypertensive subjects who had flight from Yamburg-Moscow-Yamburg.
  
  
  CONCLUSIONS
  The data of the study dictate the necessity to develop a differentiated risk strategy for health promotion, prevention and treatment of hypertension in those who work in the North of Tyumen Region in duty regime.
