Cerebrovascular and Carotid Artery Diseases

Arterial stiffness is an important risk factor for cardiovascular disease. Carotid-femoral pulse wave velocity (cfPWV) is the most recognized and established index of arterial stiffness. An emerging automatic measure of PWV primarily used in the Asian countries is brachial-ankle PWV (baPWV).To systematically compare these two methodologies, we conducted a multicenter study involving a total of 2287 patients.There was a significant positive relation between baPWV and cfPWV (r = 0.73). Average baPWV was approximately 20% higher than cfPWV. Both cfPWV and baPWV were significantly and positively associated with age (r = 0.56 and 0.64), systolic blood pressure (r = 0.49 and 0.61), and the Framingham risk score (r = 0.48 and 0.63). The areas under the receiver operating curves (ROCs) of PWV to predict the presence of both stroke and coronary artery disease were comparable between cfPWV and baPWV.Collectively, these results indicate that cfPWV and baPWV are indices of arterial stiffness that exhibit similar extent of associations with cardiovascular disease risk factors and clinical events.
