Reference Values of Pulse Wave Velocity in South America: A Call to Action

Abstract

The measurement of pulse wave velocity (PWV) is a wellknown technique currently considered the gold standard of arterial stiffness quantification due to its simplicity, accuracy, reproducibility, and predictive valueHowever, the available contemporary PWV normal values come mostly from multicenter registries obtained in Asia, USA and Europe. In South America, the reference values used are those derived from a European population, published by the Arterial Stiffness Collaboration Group. Finally, it is important to emphasize the need for epidemiological studies in South America, to provide reliable reference values of arterial stiffness, which still remains a challenge for our region.
