It was done the analysis of Doppler aspects of hypertensive remodeling of common carotid arteries in patients with high-normal blood pressure and with essential arterial hypertension of the 1-st stage, 1–2 degree, low-risk, without subclinical lesion of target organs. The diameter of common carotid arteries, the intima – media complex thickness, the maximum, minimum, average, volume average blood flow velocity, the Purselo’s index (IR), the Gosling’s index (IP), the ratio of maximum systolic blood flow velocity to the maximum diastolic rate (S/D) were considered. A study in patients with high blood pressure showed an increase in diameter of the common carotid artery, a significant increase in the intima – media complex thickness, IR, IP, S/D and a significant reduction of the maximum, minimum and average volume blood flow velocity. With the increasing degree of arterial hypertension grew revealed changes, the most significantly in patients with arterial hypertension of the 2nd degree. As a result the conditions of supply of brain structures are violated. Even at the high-normal blood pressure starts increasing the diameter of the common carotid artery, increasing the thickness and decreasing the elasticity of its walls, increasing muscle tone of the vascular wall in the background of the volume blood flow velocity reduction due to the increase in peripheral resistance to blood flow. Consequently, to prevent hypertensive remodeling of the common carotid arteries and prevention of violations of cerebral circulation it is necessary to conduct regular antihypertensive therapy even at high normal blood pressure.
