Investigation of the autonomic nervous system in patients with chronic heart failure and chronic cerebral ischemia

Abstract

The number of scientific studies which proving that the cause of many chronic diseases is the autonomic nervous system dysfunction has increased. The changes in the autonomic nervous system can be detected before the appearance of clinical symptoms. This is the basis of prevention. Reducing the influence of the parasympathetic nervous system and activating the sympathetic nervous system are predictors of arterial hypertension, cardiovascular diseases, diabetes and others. There are no clear mechanisms for the emergence of hyperactivity of the sympathetic nervous system in cardiovascular pathology. That is why it needs to be studied. And that is why the study of the influence of the autonomic nervous system in chronic conditions is relevant.
