of oscillometric (Arteriograph), piezoelectronic (Complior)
and tonometric (SphygmoCor) techniquesM

Background Arterial stiffness, measured as aortic
pulse wave velocity (PWV), and wave reflection,
measured as augmentation index (AIx), are independent
predictors for total and cardiovascular morbidity and
mortality. The aim of this study was to compare a new
device, based on oscillometric pressure curves
(Arteriograph), which simultaneously measures PWV and
AIx, with standard techniques for measuring PWV
(Complior) and AIx (SphygmoCor) in untreated
hypertensive patients.
Methods We compared PWV and AIx measured using the
Arteriograph with corresponding Complior and
SphygmoCor measurements in 254 untreated hypertensive
patients, age 48W14 years (meanWSD, range 17–85
years).
Results Arteriograph PWV and AIx were closely related with
Complior (rU0.60, P<0.001) and SphygmoCor (rU0.89,
P<0.001), respectively. Using stepwise regression analysis,
the independent determinants of Arteriograph PWV were
age, mean arterial pressure, heart rate and sex (r2U0.44,
P<0.0001) and for AIx were age, weight, mean arterial
pressure, heart rate and sex (r2U0.65, P<0.0001). The bias
between the different techniques was determined by age
and sex for PWV and age, body weight, sex, heart rate and
