SIGNIFICANCE OF THE AUTONOMOUS SYSTEM CONDITION AND BLOOD PRESSURE VALUES IN PATIENTS WITH ARTERIAL HYPERTENSION IN THEIR OUTPATIENT SURVEILLANCE WITH THE AIM OF REPEATED HOSPITALIZATION RISK ASSESSMENT

Abstract

Aim. To evaluate the relation of the autonomous system functioning with circle-round characteristics of blood pressure (BP) in patients with arterial hypertension (AH) depending on repeated hospitalizations.Material and methods. Totally 60 AH patients studied with the Wein A. M. Questionnaire, Bayevsky’s cardiointervalography, ambulatory BP monitoring and their physical activity and sleep quality.Results. In AH patients, that had repeated hospitalizations there is 15-16% increase of the mean clock-round BP and increase of time indexes, of variability and values of morning BP increase with the prevalence of “non-dipper” pattern. Also for these patients, “vegetative” complaints were more common, mostly on sleep disorders, which was evidenced by a decrease of sleep effectiveness and vegetative dysbalance. There was correlation of daytime physical activity with more prominent nocturnal systolic BP decrease. By multifactorial analysis, repeated hospitalizations were related to clock-round BP, age, mean BP, sleep effectiveness and presence of vegetative dysbalance.Conclusion. It is necessary to include the factors revealed for risk assessment of AH destabilization and repeated hospitalizations risk.
