What is Comparing Oscillometric and Tonometric Methods to Assess Pulse Wave Velocity: a Population-based Study about?

## Abstract ## Background Oscillometric pulse wave velocity (o-PWV) represents an attractive, non invasive and non operator-dependent method to estimate arterial stiffness. Tonometric carotid-femoral measurements (cf-PWV),are considered the gold-standard for non-invasive aortic stiffness assessment. To date, no studies in the general population comparing the two methods have been performed. ## Methods and Results 1162 subjects were analysed. O-PWV and cf-PWV showed a mean difference of −0.31 m/sec(__p__ ≤ 0.001). No significant differences between cf-PWV and o-PWVs were observed in patients without cardiovascular risk factors. The Bland and Altman analysis showed a moderate agreement between 24 h-o-PWV and cf-PWV (mean difference −0.99, LoA 4.23 to −6.22m/s). O-PWVs underestimate and overestimate arterial stiffness under and over 50 years respectively(__p__ ≤ 0.001). Systolic blood pressure (SBP) and age differently impact cf-PWV and in office o-PWV variability (__r__^2^ 0.35 and 0.88 respectively). In younger subjects a strong relationship between o-PWV and SBP reducing as age increases was found. Analysing the impact of age, an opposite trend was noticed. ## Conclusions Oscillome
