Resumen *

Our aim was to validate a new device for pulse wave velocity (PWV) measuremente Aortic according to the recommendations of the Artery Society and using SphygmoCor as thecomparator device.Methods: 85 subjects 18e80 years-old from both sexes were included, divided into 3 agegroups:<30, 30e60 and >60 years (minimum of 25 individuals per group) and with an equalnumber 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 3with SphygmoCor, in an alternate fashion. The BlandeAltman method was used to establish thelevel 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: rZ0.89, p < 0.001. Applying the BlandeAltman method, the meandifference between devices was 0.02 (0.84) m/s, which is considered an excellent level ofagreement. Of the study population, 75.3% (n Z 64), 15.3% (n Z 13) and 9.4% (n Z 8) reachedan excellent (mean difference 0.5 0.8 m/s), acceptable (mean difference 1.0 1.5 m/s)and poor (mean difference 1.0 1.5 m/s) level of agreement, respectively.Conclusion: Aortic showed an excellent level of agreement with SphygmoCor, the referencemethod, according to the Artery Society recommendations for PWV measurement. This wasobserved particularly for lower PWV values. Información suministrada por el agente en SIGEVA
