Objectives Recently, a novel method to estimate aortic
pulse wave velocity (aPWV) noninvasively from an
oscillometric single brachial cuff waveform reading has
been introduced. We investigated whether this new
approach provides acceptable estimates of aPWV
compared with intra-aortic catheter measurements.
Methods Estimated values of aPWV obtained from
brachial cuff readings were compared with those obtained
using an intra-aortic catheter in 120 patients (mean age
61.8±10.8 years) suspected for coronary artery disease
undergoing cardiac catheterization. Differences between
aPWV values obtained from the test device and those
obtained from catheter measurements were estimated
using Bland-Altman analysis.
Results The mean difference±SD between brachial
cuff-derived values and intra-aortic values was
0.43±1.24 m/s. Comparison of aPWV measured by the two
methods showed a significant linear correlation (Pearson´s
R =0.81, P < 0.0001). The mean difference for repeated
