“…Among them, pulse wave velocity (PWV) [1][2][3][4][5][6][7], augmentation index [8], the stiffness parameter β [9,10], and carotid-femoral PWV [11] have been proposed as markers of arterial stiffness. In 2002, brachial-ankle PWV was proposed as a marker of vascular damage [12], and was reported to be a predictive factor of coronary artery disease [13]. However, PWV is known to depend on blood pressure at the time of measurement [14].…”
