The state of peripheral and central hemodynamics was examined in 603 workers engaged into shifted duty expeditions in West Siberia, considering the length of service in the shifted duty cycle. The examination revealed high occurrence of cardiovascular diseases with prevalent hypertension. Rheographic findings proved that in 5 years of the shifted duty work high blood pressure develops with increased peripheral vascular tone (especially in brain) and enhanced contractility of left ventricle. Important role in the high blood pressure formation is played by changes of hemodynamics in first days after the duty shift.
