P2.18 Study of the Determinants of Pwv Measured by Arteriograph and Sphygmocor and the Determinants of Discrepancies

Introduction Large artery stiffness is recognized as a strong, independent marker of cardiovascular risk, mainly through aortic pulse wave velocity (PWV). Arteriograph is a non-invasive oscillometric method, which estimates aortic PWV through brachial pressure wave analysis. Aim To compare the determinants of PWV measured with Arteriograph (Ar PWV) to carotid-femoral PWV (CF PWV) determinants and to study the determinants of discrepancies. Methods CF PWV was assessed by applanation tonometry (SphygmoCor®) and Ar PWV was assessed by Arteriograph. Multivariate analysis and stepwise regression was performed to study the determinants and Pearson’s coefficient to study correlations. Results 90 subjects were included: 30 healthy subjects and 60 patients with essential hypertension. The correlation between Ar PWV and CF PWV is good (r=0.77; p
