Invasive validation of a new oscillometric device (Arteriograph) for measuring augmentation index, central blood pressure and aortic pulse wave velocity

Abstract

Aix, SBPao and PWVao, measured oscillometrically, showed strong correlation with the invasively obtained values. The observed limits of agreement are encouragingly low for accepting the method for clinical use. Our results suggest that the PWVao values, measured by Arteriograph, are close to the true aortic PWV, determined invasively.

Increased aortic stiffness in ulcerative colitis

“…Stefanadis et al described that such noninvasive measurements of aortic elastic properties by echocardiography are as accurate as invasive methods [7]. PWV and Aix are another two major characteristics of arterial stiffness, their measurement by Arteriograph has recently been validated [4,[8][9][10].…”

“…The aortic elasticity parameters was calculated as follows: Pulse-wave assessment. The oscillometry-based Arteriograph device was used in all cases to measure aortic PWV and Aix [4,[8][9][10]. It is based on the complete occlusion of the brachial artery by a simple cuff allowing recording and separation of pronounced early forward and late reflected systolic waves [8][9][10].…”

Measurement of arterial stiffness and wave reflections: does body position matter?

“…Based on the Bland-Altman plots, in the Nürnberger study the Arteriograph system seems to meet published criteria for 'acceptable' accuracy, 6 which is in line with a recently reported invasive validation study. 12 As to the Vascular Explorer system, Bland-Altman plots in comparison with the tonometric system are compatible with systematic bias. Moreover, for both oscillometric systems, clinical validation (that is, based on clinical outcomes) is lacking.…”
