Validation of a new piezo-electronic device for non-invasive measurement of arterial pulse wave velocity according to the artery society guidelines

Abstract Our aim was to validate a new device for pulse wave velocity (PWV) measurement – Aortic according to the recommendations of the Artery Society and using SphygmoCor as the comparator device. Methods 85 subjects 18–80 years-old from both sexes were included, divided into 3 age-groups: 60 years (minimum of 25 individuals per group) and with an equal number of hypertensive and normotensive subjects per group. Weight, height, blood pressure (BP) and PWV were assessed, performing 6 PWV determinations per subject: 3 with Aortic and 3 with SphygmoCor, in an alternate fashion. The Bland–Altman method was used to establish the level of agreement between the two devices. Results PWV was 6.96 (±1.84) and 7 (±1.54) m/s with Aortic and SphygmoCor, respectively, showing a high correlation: r = 0.89, p  Conclusion Aortic showed an excellent level of agreement with SphygmoCor, the reference method, according to the Artery Society recommendations for PWV measurement. This was observed particularly for lower PWV values.
