Purpose — studying of parameters of integrated indicators of blood circulation and definition of types of hemodynamics at healthy young people.

428 healthy volunteers aged from 18 till 30 years, middle age 24,0±3,7 (M±σ) years, from them 244 women and 184 men are examined. At an echocardiography defined SV and СО. On model of cardiac-vascular system counted the modulus of volume elasticity (MVE), an average arterial pressure, the total peripheral vascular resistance (TPVR), MVE/TPVR. Defined hemodynamics types according to the СО hyperkinetic, eukinetic and hyperkinetic types. On MVE/TPVR ratio — with prevalence of rigidity of arterial system or peripheral vascular resistance. The analysis of parameters of hemodynamics of healthy patients depending on a sex and the level of normal arterial pressure is carried out. At women lower values of peripheral vascular resistance and higher MVE and MVE/TPVR are revealed. At increase in level of normal arterial pressure values of TPVR increased its vascular peripheral resistance. The hyperkinetic type of hemodynamics is revealed at 16,1% of patients, eukinetic type at 63,6%, hypokinetic in 20,3% of cases. Prevalence of rigidity of arterial system it was observed in 12,4% of cases, prevalence of peripheral resistance in 87,6%.

Conclusions. Healthy young age people are non-uniform on integrated indicators of hemodynamics. It is possible to distinguish patients with various types of blood circulation in parameters of cardiac output from them (hyperkinetic, eukinetic, hypokinetic) and in the MVE and TPVR parameters — with prevalence of rigidity of arterial system and prevalence of the general vascular peripheral resistance.

Key words: stiffness of the arterial system, types of hemodynamics, hemodynamics of healthy people.
