Abstract
A computer-implemented method for quantifying arterial stiffness and assigning an AS factor uses executable program on a computing device. The arterial pulse of an individual is monitored and the data received from the monitoring member transmitted to the computing device. The data received is processed by the processor, performing a pulse wave analysis. The primary systolic pulse and iliac reflection pulse are extracted from the pulse wave analysis and the time delay between the primary systolic pulse and the iliac reflection pulse determined. The time delay is used to calculate a second derivative based least in part, on the time delay. The frequency above zero components are separated from the second derivative and the area of the second derivative determined between a first primary systolic pulse and a first iliac reflection pulse. A percentage score is calculated based on the degree of arterial stiffness and input into a historical population database comparing the percentage score with the population data.
