Reference values of carotid-femoral pulse wave velocity (PWV1), the gold standard measure of arterial stiffness, and local carotid2 and femoral3 arterial stiffness, derived from the distensibility coefficient (DC), have been established. The use of different devices and methods, however, still hampers the widespread clinical use of these reference values. With this calculator, we provide a web-based application that allows easy assessment – for different methodological approaches – of a given measured value of arterial stiffness, with the application providing the percentile reference value associated with that specific value. Individuals without CVD and established cardiovascular risk factors from the respective studies constituted a healthy subpopulation and were used to establish equations for percentiles of PWV and sex-specific percentiles of carotid and femoral DC across age.
