Prolonged hypertension stiffens rat carotid arteries independent of wall stress; leaves open translation to human vascular risk and requires prospective clinical studies.
Does prolonged renal hypertension alter the mechanical properties of the carotid artery in rats?
Prolonged hypertension in a rat model leads to increased arterial stiffness over time despite constant wall stress, potentially predisposing to accelerated vascular alterations.
Zanchi et al. (1997) studied this question.
