Abstract
The photoplethysmogram (PPG) signal is widely measured by clinical and consumer devices,
and it is emerging as a potential tool for assessing vascular age. The shape and timing of the PPG
pulse wave are both influenced by normal vascular ageing, changes in arterial stiffness and blood
pressure, and atherosclerosis. This review summarises research into assessing vascular age from the
PPG. Three categories of approaches are described: (i) those which use a single PPG signal (based on
pulse wave analysis); (ii) those which use multiple PPG signals (such as pulse transit time
measurement); and (iii) those which use PPG and other signals (such as pulse arrival time
measurement). Evidence is then presented on the performance, repeatability and reproducibility,
and clinical utility of PPG-derived parameters of vascular age. Finally, the review outlines key
directions for future research to realise the full potential of photoplethysmography for assessing
vascular age.
