ABSTRACT:
An arteriostenosis diagnosing apparatus which measures an ankle blood pressure at an ankle12of a patient and a brachium blood pressure at a brachium14, so that the measured ankle and brachium blood pressure values are used to calculate an ankle and brachium blood pressure index ABI, and additionally measures a first pulse wave propagation velocity PWV1with respect to the ankle12as a first measuring point and the brachium14as a second measuring point, and a second pulse wave propagation velocity PWV2with respect to the patient's heart and the brachium14. The arteriostenosis diagnosing apparatus includes an arteriostenosis judging device100which judges, even if the index ABI may fall in a prescribed normal range or a prescribed alert range and the first velocity PWV1falls in a prescribed normal range, that there is a possibility that an inferior limb including the ankle12at which the ankle blood pressure has been measured, may have arteriostenosis, if the second velocity PWV2falls in a prescribed abnormal range.
