Changes in carotid arterial wall viscosity and carotid arterial stiffness in type 2 diabetes patients.

ABSTRACT:

Background and aims

Changes in arterial wall viscosity (AWW) and stiffness during type 2 diabetes (T2D) have been little investigated. We explored changes in carotid AWV considering change in arterial stiffness and loading conditions, in patients with T2D.

Methods

This cross-sectional, monocentric study compared 19 middle-aged patients with T2D to 30 non-diabetic (ND) controls. The absolute viscosity (W_V) was determined as the area of the pressure-lumen cross-sectional area (P-LCSA) loop obtained by carotid tonometry and contralateral echo-tracking. The relative viscosity was determined as the ratio between W_V and the elastic energy stored within the arterial wall (W_V/W_E). Carotid geometry, midwall stress, distensibility and elasti
