Abstract
An arteriosclerosis inspecting apparatus including an information obtaining device which obtains information that is related to a velocity at which a pulse wave propagates in a living subject, 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-augmentation-index determining means for determining an arteriosclerosis-inspection-related augmentation index of the subject, based on the obtained pulse-wave-velocity-related information, the measured blood pressure, the measured heart rate, the measured pre-ejection period, and the measured ejection time, according to a predetermined relationship between (A) (a1) pulse-wave-velocity-related information, (a2) blood pressure, (a3) heart rate, (a4) pre-ejection period and (a5) ejection time, and (B) arteriosclerosis-inspection-related augmentation index.
