Background The importance of measuring aortic pulse
wave velocity (PWVao), aortic augmentation index (Aix) and
central systolic blood pressure (SBPao) has been shown
under different clinical conditions; however, information on
these parameters is hard to obtain. The aim of this study
was to evaluate the accuracy of a new, easily applicable
oscillometric device (Arteriograph), determining these
parameters simultaneously, against invasive
measurements.
Methods Aortic Aix, SBPao and PWVao were measured
invasively during cardiac catheterization in 16, 55 and
22 cases, respectively, and compared with the values
measured by the Arteriograph.
Results We found strong correlation between the invasively
measured aortic Aix and the oscillometrically measured
brachial Aix on either beat-to-beat or mean value per patient
basis (rU0.9, P<0.001; rU0.94, P<0.001), which allowed
the noninvasive calculation of the aortic Aix without using
generalized transfer function. Similarly strong correlation
(rU0.95, P<0.001) was found between the invasively
measured and the noninvasively calculated central SBPao;
furthermore, the BHS assessment of the paired differences
fulfilled the ‘B’ grading. The PWVao values measured
invasively and by Arteriograph were 9.41W1.8 m/s and
