Digital photoplethysmography is a portable and reproducible method for measuring arterial stiffness, with normal ranges influenced by demographic and physiological factors.
Individualized arterial stiffness norms may aid interpretation; leaves open whether photoplethysmography refines risk stratification.
Digital photoplethysmography is a portable, operator-independent, reproducible and simple method of measuring arterial stiffness. Ranges of normality of arterial stiffness will depend on the individual's age, race, lipid levels, HR and blood pressure.
