[Various neurohumoral aspects of hemodynamic changes in patients with hypertension after correction of electrolyte disorders].

Changes in activity of sympathetic-adrenal and + renin-angiotensin-aldosterone systems (SAS and RAAS), hemodynamics and electrolyte metabolism when correcting sodium balance in consideration of their "salt sensitivity" were studied in 83 hypertension stage I and II patients. In moderate restriction of sodium chloride response of the patients was not uniform. "Salt--sensitive" subjects responded positively with improvement of central and peripheral hemodynamics, electrolyte balance in enhanced activity of SAS and RAAS. In salt nonresponders and in paradoxical sensitivity SAS and RAAS show activation, most distinct in paradoxical sensitivity, and worse central and peripheral hemodynamics, electrolyte imbalance.
