In the study of the state of central hemodynamics (CH) and peripheral hemodynamics (PH) in patients with hypertension in combination with obliterative atherosclerosis of the lower extremities (OALE), the importance of autonomic nervous regulation is important.
The aim of the study – to investigate the effect of the state of the autonomic nervous system on the central and peripheral hemodynamics of patients with hypertension in combination with the obliterative atherosclerosis of the lower extremities.
Results. Three types of hemodynamics were established in hypertensive patients in combination with OALE after the reconstructive surgical interventions: the hyperkinetic type was observed in 32.1 % of patients (elevation of heart index (HI) above 3.7l/(min×m2) with a decrease in specific peripheral vascular resistance (SPVR) (less than 110.0 (0.1×kPa×s/(l×m2)), the hypokinetic type is 38.7 % (decrease in HI is less than 2.2l/(min×m2) while increasing SPVR over 190.0 (0.1×kPa×s/(l×m2)); eukinetic type – in 29.2 % (values of SI and SPVR were within the aforementioned types of hemodynamics).
Conclusion. In hypertonic disease in combination with obliterative atherosclerosis of the lower extremities with a hypokinetic type of hemodynamics, 59.1 % of patients noted an increase in the tonus of the parasympathetic component of the VNS and the presence of an underdeveloped collateral channel of the lower extremities, and 89.3 % of the eu- and hyperkinetic hemodynamic types were prevalence sympathetic component of the VNS with a sufficiently developed collateral channel that is capable of increasing the functional load.
