Pulse Wave Velocity as Marker of Preclinical Arterial Disease: Reference Levels in a Uruguayan Population Considering Wave Detection Algorithms, Path Lengths, Aging, and Blood Pressure
Figure 2
PWV nomograms for the reference population with percentiles (p) 97.5, 50, and 2.5. Broken lines indicate mean confidence interval. The dashed areas illustrate differences between the threshold defined from our population and the fixed unique threshold proposed in the ESH/ESC Guidelines. For PWVReal the fixed unique threshold proposed by Boutouyrie et al. (9.6 m/s) was included [3]. Note that the fixed threshold of PWV = 12 m/s or 9.6 m/s determines an underestimation and overestimation to detect preclinical arterial wall damage in young and old subjects, respectively. Underestimation or overestimation would differ depending on the subjects’ age and the algorithm used to assess PWV.
