Abstract
An apparatus for evaluating arteriosclerosis of a living subject, including a blood-pressure measuring device which measures at least one blood-pressure value of the subject, a pulse-wave detecting device which detects a pulse wave from a portion of the subject, a relationship determining device for determining a relationship between pulse-wave magnitude and blood pressure, based on at least one magnitude of the pulse wave detected by the pulse-wave detecting device and said at least one blood-pressure value measured by the blood-pressure measuring device, an incident-wave-peak determining device for determining a magnitude of a peak point of an incident-wave component which is contained in the pulse wave detected by the pulse-wave detecting device, a reflected-wave-occurrence-time determining device for determining a time of occurrence of a peak point of a reflected-wave component which is contained in the pulse wave, a pressure-difference determining device for determining, according to the relationship between pulse-wave magnitude and blood pressure, a pressure difference corresponding to a magnitude difference between a magnitude of the pulse wave at the time of occurrence of the peak point of the reflected-wave component, and the magnitude of the peak point of the incident-wave component, and a display device which displays the pressure difference determined by the pressure-difference determining device.
