INTERRELATION BETWEEN SUBCLINICAL STRUCTURAL CHANGES OF SLEEP ARTERY AND COGNITIVE FUNCTIONS IN PATIENTS WITH HYPERTENSION DISEASE

Abstract

Introduction. At present, a number of clinical studies have confirmed the relationship between blood pressure and cognitive impairment. Objective. The aim of the study was to analyze the relationship between cognitive impairment and subclinical changes in carotid arteries in hypertensive patients. Material and methods. 69 patients with hypertensive disease of the II stage, average age of 51.38 ± 0.94 years, were examined. Patients were divided into 2 groups with absence and presence of cognitive impairment. The examination of the right common carotid artery was carried out using an ultrasound multifunction scanner. To study cognitive impairment used a number of MoCA test. Results. The average thickness of the intima-media complex in the patients of the first and second groups was not significantly different. The proportion of people with intima-media complex thickness exceeding normal values was significantly higher in persons with cognitive impairment (71%) than in persons without them (39.5%). Сonclusions. In patients with stage II of hypertensive disease, the thickness of the intima-media complex of the carotid artery was increased. A positive correlation of increased thickness of the intoma-media complex with hypertensive crises was found only in persons with cognitive impairment.
