title: [Pathomorphologic changes in the sympathetic portion of the autonomic nervous system and cardiovascular pathology].
abstract: Neurohistochemical and ultrastructural study of the sympathetic innervation of the cardiovascular system indicated its important role in the age alterations and genesis of certain diseases. Early beginning (from the age of 30) of the involution of the heart adrenergic plexus is confirmed in healthy persons. Focal desympathization of the myocardium is detected in sudden cardiac death. A decrease of sympathetic plexus density in zones undergoing atherosclerotic changes is of importance in the genesis of atherosclerosis. In arterial hypertension a primary stage of sympathetic neurones hypertrophy is changed into the phase of the mediators exhaustion in the sympathetic plexus. Myocardiopathies are characterized by progressing myocardial desympathization. An important problem of cardiosurgery is methods of heart reinnervation at its transplantation.
