Purpose. To study elastic properties of carotid arteries in young men with arterial hypertension (AH). Material and methods. We examined men aged 18-25 years (mean 21.1 ±0.14 years): 36 with normal blood pressure (BP), 123 with stable and 51 with unstable AH. Parameters studied comprised intima-media thickness (IMT) of carotid arteries, their M-mode measured maximal systolic and minimal diastolic diameters (Ds and Dd), stiffness of common carotid artery (CCA) wall determined on the basis of analysis of elasticity and distensibility coefficients (CC and DC), Peterson's and Young's modules of elasticity (Ep and E), and index of flow deformation (CS). Results. Compared with young men with normal BP and unstable AH patients with stable AH had abnormal elastic properties of CCA and increased IMT. Conclusions. Stable AH in young men is associated with signs of remodeling of CCA walls and increase of their rigidity.
