*5.2.3 Cardio-ankle vascular index: CAVI*

The cardio-ankle vascular index (CAVI) is a representative parameter for evaluating arterial stiffness. Because CAVI is obtained by calculating the stiffness parameter β, which indicates the intrinsic stiffness of the blood vessels, CAVI is also theoretically independent of blood pressure. One study reported that there was no significant difference between the KD group without CAL and the control group [37]. CAVI assesses more central vascular stiffness than PVW; therefore, it is speculated that injury to the great vessel may be mild or absent in KD vasculitis. Because CAVI is a relatively new parameter, further studies are needed to elucidate vascular function in patients with a history of KD.
