Inter-operator Reliability for Measuring Pulse Wave Velocity and Augmentation Index

Aortic pulse wave velocity, reflection site distance, and augmentation index.

Endothelial function is associated with pulse pressure, pulse wave velocity, and augmentation index in healthy humans.

Arterial stiffness is an independent predictor of mortality and is regulated by a number of factors, including vascular smooth muscle tone. However, the relationship between endothelial function and definitive measures of arterial stiffness and wave reflections has not been described in healthy individuals. Therefore, we tested the hypothesis that endothelial function is inversely correlated wi...

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

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 ...

Ambulatory arterial stiffness index, pulse wave velocity and augmentation index--interchangeable or mutually exclusive measures?

BACKGROUND The ambulatory arterial stiffness index (AASI) has been proposed as a novel measure of arterial stiffness and has been prospectively shown to predict stroke and cardiovascular death, but not cardiac death. This index has prompted considerable controversy as to whether it is a true measure of arterial stiffness. OBJECTIVE AND METHODS The present study aimed to examine three differen...

Diabetic retinopathy is associated with pulse wave velocity, not with the augmentation index of pulse waveform

BACKGROUND To investigate the clinical differences between pulse wave velocity and augmentation index in diabetic retinopathy. METHODS The subjects were 201 patients with type 2 diabetes. These subjects were measured for both augmentation index (AI) and brachial-ankle pulse wave velocity (baPWV) by a pulse wave analyzer. The relationships between AI, baPWV, and diabetic retinopathy were exami...
