AGE-RELATED ASPECTS OF ULTRASONIC HYPERTENSIVE REMODELING OF COMMON CAROTID ARTERIES IN PATIENTS WITH ARTERIAL HYPERTENSION OF THE 1ST STAGE, OF 1-2 DEGREES, WITHOUT SUBCLINICAL LESIONS OF TARGET ORGANS
It was done the analysis of Doppler gender-age-related aspects of hypertensive remodeling of common carotid arteries in patients with high blood pressure. It was considered: the diameter of the common carotid arteries, the thickness of the intima–media complex (IMC), the maximum linear velocity of blood flow (Vmax), the minimum linear velocity of blood flow (Vmin), the average velocity of the blood flow (Vmed), volume average velocity of the blood flow (Vvol med), the Purselo's index of circulatory resistance (IR), the Gosling's pulsation index (IP), the ratio of maximum systolic velocity of blood flow to the maximum diastolic rate (S/D). As a result of study in patients with high blood pressure it is revealed an increase in the diameter of the common carotid artery, a significant increase in the thickness of the intima–media complex, a reduction of the maximum, minimum and average volume velocity of blood flow, and a significant increase in IR, IP, S/D, indicating the increase in the density of vascular walls and the increase in peripheral resistance to blood flow. Significant difference between a condition of the common carotid arteries, depending on age, for men and women with high blood pressure is not revealed. Consequently, to prevent the development of hypertension remodeling of the carotid arteries and prevention of violations of cerebral circulation it is necessary to conduct regular antihypertensive therapy regardless of sex and age.
