Arteriosclerosis inspecting apparatus

An apparatus for inspecting arteriosclerosis of a living subject, comprising:

• an augmentation-index measuring device which measures an augmentation index of the subject that is a proportion of a magnitude of a reflected-wave component of a pulse wave of the subject to a magnitude of an incident-wave component of the pulse wave;
• a blood-pressure measuring device which measures a blood pressure of the subject;
• a heart-rate measuring device which measures a heart rate of the subject;
• a pre-ejection-period measuring device which measures a pre-ejection period from a time of starting of contraction of the heart of the subject to a time of starting of ejection of blood from the heart;
• an ejection-time measuring device which measures an ejection time from the time of starting of ejection of blood from the heart to a time of ending of ejection of blood from the heart;
• and
• an arteriosclerosis-inspection-related-pulse-wave-velocity-related-value determining means for determining an arteriosclerosis-inspection-related pulse-wave-velocity-related value of the subject, based on the augmentation index measured by the augmentation-index measuring device, the blood pressure measured by the blood-pressure measuring device, the heart rate measured by the heart-rate measuring device, the pre-ejection period measured by the pre-ejection-period measuring device, and the ejection time measured by the ejection-time measuring device, according to a predetermined relationship between (A) (a1) augmentation index, (a2) blood pressure, (a3) heart rate, (a4) pre-ejection period and (a5) ejection time, and (B) arteriosclerosis-inspection-related pulse-wave-velocity-related value.
