Stiffening of Aortic Wall Linked With Increased Risk of High Blood Pressure, JAMA Reveals

An analysis of the relationship between several vascular function measures and blood pressure levels finds that certain measures including higher aortic stiffness were associated with a higher risk of new hypertension; however, initial blood pressure was not independently associated with risk of progressive aortic stiffening, suggesting that vascular stiffness may be a precursor rather than the result of hypertension, according to a study in the September 5 issue of JAMA. "Vascular stiffness increases with advancing age and is a major risk factor for age-related morbidity and mortality. A compliant aorta provides an important buffer for each ventricular contraction that maintains pulse pressure at low levels.
