ASSESSMENT OF THE RISK FACTORS FOR THE DEVELOPMENT OF CARDIOVASCULAR DISEASES AND AUTONOMIC PARAMETERS IN PATIENTS WITH CHRONIC BRAIN ISCHEMIA AND CONGESTIVE HEART FAILURE
This topic is relevant because activation of the sympathetic nervous system is often a predictor of the development of diseases of the cardiovascular system, and identifying an increase in the activity of the sympathetic division of the autonomic nervous system in the early stages is one of the key moments in preventing the progression of cardiovascular diseases. The article presents data on the determination of the state of the autonomic nervous system in patients with chronic brain ischemia and chronic heart failure. The purpose of the study is to assess the state of the autonomic nervous system, risk factors for the development of cardiovascular diseases in 120 patients with chronic brain ischemia and chronic heart failure. Material and methods. We analyzed the presence of various risk factors in groups, and for the purpose of studying the autonomic nervous system, we used questionnaires, determined vegetative indices and determined vegetative reactivity using effects on reflex zones. Result and discussion. It was found that in patients with a reduced left ventricular ejection fraction, the prevalence of the sympathetic component of the autonomic nervous system was recorded more often. A statistically significant difference was obtained in myocardial infarction, chronic obstructive pulmonary disease and valvular heart disease between the 1st and 2nd groups. Conclusion. Patients with chronic cerebral ischemia with chronic heart failure and a reduced left ventricular ejection fraction have more risk factors for cardiovascular diseases and comorbid pathology
