Carotid Stiffness: A Novel Cerebrovascular Disease Risk Factor.

Abstract

Carotid stiffening is considered an important element in the pathogenesis of cerebrovascular diseases. These include stroke as well as vascular dementia and depression. However, results of individual studies evaluating the association between carotid stiffening and incident stroke have been inconsistent. Therefore, we have conducted a systematic review and meta-analysis, showing that carotid stiffening is associated with incident stroke independently of cardiovascular risk factors and aortic stiffness. In addition, carotid stiffening improved stroke risk prediction beyond the Framingham stroke risk factors and aortic stiffness. Other studies have shown that carotid stiffening is associated with a higher incidence of vascular dementia and depressive symptoms. This suggests that carotid stiffness is a potential separate target for prevention strategies of cerebrovascular disease.
