title: [State of the vegetative nervous system and the risk of repeated hospitalization after elimination of hypertonic crisis].
abstract: Observation of 58 outpatients with arterial hypertension (AH) revealed a group of 25 subjects who needed repeated hospitalization within 1 year after hypertonic crisis due to unstable conditions (group 1). The two groups were comparable in terms of office AP measurements, but 24 hr AP, systolic AP and its variations were significantly higher while daily index was lower in group 1. Moreover, patients of this group had decreased variability of the cardiac rhythm with increased activity of the suprasegmental level and reduced parasympathetic activity. A rise in BMI in these patients correlated with the state of sympathetic component of the vegetative nervous system. It is concluded that normalization of office AP can not be regarded as evidence of benign course of the disease; evaluation of daily AP characteristics, BMI, and balance of vegetative nervous system is needed to stratify risks for the outpatients with AH followed up after the treatment of hypertonic crisis.
