Carotid atherosclerosis and 24-hour blood pressure profile in indigenous and alien populations of the Far North

Objectives: To study the patterns of atherosclerotic lesions in brachiocephalic arteries, 24-hour blood pressure monitoring data, and heart rate variability in patients with arterial hypertension (AH) and coronary artery disease (CAD) among indigenous and alien populations of Yamalo-Nenets Autonomous District. A total of 100 patients aged 21-55 years (mean age of 52.3±0.4 years) with AH and CAD living in the Far North were examined. All patients were divided into two groups of 50 people each: group I included native population, group II included alien population. The patients underwent outpatient duplex scanning of brachiocephalic arteries and 24-hour blood pressure monitoring; heart rate variability and lipid profile were evaluated. Groups matched by age and gender. Duplex scanning of brachiocephalic arteries detected thickening of the intima-media complex of the common carotid artery in all patients: the highest level was observed in native inhabitants (p
