Abstract
An approach based pulse on contour analysis is proposed for the development of an aging index for the vascular system. The approach is non-invasive, using photoplethysmography (PPG), which is in wide clinical use. A probe is applied to the subject’s finger-tip to provide a measure of the pulse waveform. The measured waveforms are filtered, digitized and post-processed. Individual pulses are extracted and the best pulse was selected by using the best pulse selection algorithm. Pulse contour analysis is then performed with specially formulated PPG fitness equation. Results of measurements taken from 72 subjects are reported. The age range of the subjects was from 19 to 68 years, all of them are healthy (free from cardiovascular related risks and diseases). There are linear relationship between the PPG fitness and the age recorded from the 72 individuals. The gradient of the line of best fit tends to decrease with increasing age. An age index, which indicates vascular age, is thus proposed based on the slope of this line of best fit for a given individual.
