Abstract

The risk of cardiovascular diseases may damage the endothelium cells which may cause atherosclerosis. Arterial stiffness can be measured noninvasively by the use of photoplethysmogram (PPG) technique. This research presents the variations of PPG morphology with age. Based on a sample of 65 subjects whom having established erectile dysfunction (ED), the study proposed to assess the variations of PPG contour at two sites of measurements (right and left index finger). The study concluded that PPG timing indices are equal in both right and left hand. Parameters derived from the analysis of PPG contour showed an association with age. The age is found to be an important factor that affecting the contour of PPG signals, which accelerates the disappearance of PPG dicrotic notch and PPG inflection point as well. Arterial compliance found to be decreased with age due to the fall of arterial elasticity. This study approaches the establishment of the usefulness of PPG contour analysis in investigating the changes in the elastic properties of the vascular system with age and the detection of early atherosclerosis. The study approaches the establishment of the differences between PPG's time indices and PPG's amplitude indices.
