ABI : Ankle-Brachial index
Right ABI = 右足首収縮期血圧 / 上腕収縮期血圧
Left ABI = 左足首収縮期血圧 / 上腕収縮期血圧
*上腕収縮期血圧:左右の腕の高い値を使用
*足首収縮期血圧:後脛骨動脈(Posterior tibial a.)または足背動脈(Dorsalis pedis a.)の高い値を使用








※ ABIの解釈
(1) > 1.4 : Calcification / Vessel hardening
(2) 1.0 ~ 1.4 : Normal value
(3) 0.9 ~ 1.0 : Acceptable / Borderline PAD
(4) 0.7 ~ 0.9 : Mild PAD
(5) 0.5 ~ 0.7 : Moderate PAD
(6) < 0.5 : Severe PAD
