Features of Autonomic System in Patients with Chronic Cerebral Ischemia

O.I. Isaikova

Abstract


State of the autonomic nervous system has been studied in 62 patients with atherosclerotic and hypertensive chronic cerebral ischemia in the subcompensative stage. Significant imbalance of autonomic response towards sympathetic influences has been detected that is due to the depletion of trophotropic formations. There were no gender differences in the direction of autonomic tone and response to exercise in the study of autonomic reactivity and activities support. Prevalence of sympathetic autonomic tone has been detected in middle- and old-age patients with its increase in the older age group. It was found that insufficient autonomic reactivity dominated in patients with sympathicotonia, normal autonomic reactivity was observed in half of the patients with normal tone, and the patients with vagotonia have equally normal and excess reactivity. It was stated that insufficient autonomic activity support predominated in patients with sympathicotonia, the majority of patients with normal tone have normal activities support and one-third — insufficient. The findings open up the possibility for drug and non-drug correction of changes in the autonomic nervous system in patients with hypertensive and atherosclerotic chronic cerebral ischemia.
