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 (r U 0.9, P <
0.001; U 0.94, P < 0.001),
which allowed the noninvasive calculation of the
aortic Aix without
using generalized transfer function. Similarly strong
correlation
(r U 0.95, 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 9.41 W
1.8m/s and 9.46 W 1.8 m/s, respectively (mean W SD); furthermore, the Pearson’s
correlation was 0.91 (P < 0.001).
