THE PECULIARITIES OF THE STATE OF THE AUTONOMIC NERVOUS SYSTEM ESTIMATED BY THE METHOD OF HEART RATE VARIABILITY IN PATIENTS WITH CIRRHOSIS AND SYNTROPIC DAMAGES OF CARDIOVASCULAR SYSTEM.

In the article the features of the autonomic nervous system state were estimated by the method of heart rate variability in patients with cirrhosis with syntropic damages of cardiovascular system - cardiomyopathy and arterial hypotension. As a result of an examination of 50 patients with liver cirrhosis and cardiomyopathy (investigational group A), 54 patients with liver cirrhosis and arterial hypotension (investigational group B), and 45 patients with liver cirrhosis also those who don't have the damages of cardiovascular system (group of comparison) it was established that: 1) they have the peculiarities of vegetative imbalance the characteristics of which are the low summarized activity of vegetative influence on heart rhythm and special dynamics of indexes of percentage structure of general spectral power; 2) they depend on the clinical variant of this damage - in patients with cirrhosis and syntropic cardiomyopathy the regulating of internal processes involve the humoral-metabolic influence, i.e. local vasoactive conjunctions, catecholamines, renin-angiotensin-aldosterone system, with a simultaneous influence of sympathetic system and activity reduction of parasympathetic vegetative nervous system, and in patients with cirrhosis and syntropic arterial hypotension - the internal regulation involves the local humoral-metabolic factors with the lack of both sympathetic and parasympathetic parts of vegetative nervous system.
