METHOD FOR EVALUATING AGE OF BLOOD VESSEL

WIPO Patent Application WO/2005/102157

A1

A method for evaluating the age of blood vessel by determining a waveform index from acceleration pulse wave of a subject and making a decision as to what age waveform of a healthy person the measured waveform of acceleration pulse wave corresponds based on a distribution, by sex and age, of waveform index of a healthy person, thereby determining the age of blood vessel of a subject. When the value of waveform index obtained for the subject falls within the standard distribution range of age zone to which the subject belongs, the age of blood vessel is determined by dividing the range of young side distribution boundary-old side distribution boundary of waveform index into the age widths of age zone. When the value of waveform index obtained for the subject does not fall within the standard distribution range of age zone to which the subject belongs, the age of blood vessel is determined from the young side distribution boundary or the old side distribution boundary in the distribution of waveform index by age and sex of a healthy person.
