Introduction Pulse wave velocity (PWV) and augmentation
index (AIx) are parameters of arterial stiffness and wave
reflection. PWV and AIx are strong indicators for
cardiovascular risk and are used increasingly in clinical
practice. Previous systems for assessment of PWV and AIx
are investigator dependent and time consuming. The aim of
this study was to validate the new oscillometric method
(Arteriograph) for determining PWV and AIx by comparing it
to two clinically validated, broadly accepted tonometric and
piezo-electronic systems (SphygmoCor and Complior).
Design and method PWV and AIx were measured up to five
times in 51 patients with the SphygmoCor, Complior and
Arteriograph. In 35 patients, the measurements were
repeated after 1 week in a second session using the
same protocol.
Results The correlations of the PWV as assessed with the
Arteriograph with the values obtained using the
SphygmoCor (rU0.67, P < 0.001) and the Complior
(rU0.69, P < 0.001) were highly significant. Variability and
reproducibility for PWV were best for the Arteriograph,
