[Changes in central hemodynamics in persons with borderline arterial hypertension during work-related activities]. 1990

T I Gudkova, and V V Matiukhin, and G V Baĭkov, and I N Kas'ianova

Changes in the function of the cardiovascular system were studied in 30-39- and 40-49-year-old healthy subjects and patients with borderline arterial hypertension (BAH) who worked 8 or 12 hours every day. During an 8-hour working day, altered central hemodynamics was shown to be detected both in healthy subjects and BAH patients only at the age of 30-39 years and reflected by higher stroke volume (SV), higher cardiac output (CO) and lower total peripheral resistance (TPR) in healthy subjects and diminished heart rate (HR), CO in BAH patients. With this, the distribution of hemocirculatory patterns remained the same as it had been before work. After 12-hour work, the central hemodynamic changes were unindirectional in all the groups in question: decreased HR, SV, CO, cardiac index and increased TPR. There was a decrease in hyperkinetic hemodynamic incidence and an increase in eu- and hypokinetic hemodynamic one.
