Validity, reproducibility, and clinical significance of noninvasive brachial-ankle pulse wave velocity measurement.

Hypertension Research, 2002
The present study was conducted to evaluate the validity and reproducibility of noninvasive brachial-ankle pulse wave velocity (baPWV) measurements and to examine the alteration of baPWV in patients with coronary artery disease (CAD).

Determinants of aortic stiffness: 16-year follow-up of the Whitehall II study. [PDF]

PLoS ONE, 2012
BACKGROUND:Aortic stiffness is a strong predictor of cardiovascular disease endpoints. Cross-sectional studies have shown associations of various cardiovascular risk factors with aortic pulse wave velocity, a measure of aortic stiffness, but the long ...

In Vivo Pulse Wave Measurement Through a Multimode Fiber Diffuse Speckle Analysis System

Frontiers in Physics, 2021
Continuous monitoring of in vivo pulsatile blood flow and pulse wave velocity (PWV) is important for clinical applications. These parameters are correlated with physiological parameters, such as blood pressure and elasticity of blood vessels. A multimode

Characteristics of light reflected from a dense ionization wave with a tunable velocity [PDF]

, 2009
An optically-dense ionization wave (IW) produced by two femtosecond laser pulses focused cylindrically and crossing each other is shown to be an efficient coherent x-ray converter. The resulting velocity of a quasi-plane IW in the vicinity of pulse intersection increases with the angle between the pulses from the group velocity of ionizing pulses to ...

Increased Pulse Wave Velocity in Subclinical Hypothyroidism [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2006
Subclinical hypothyroidism affects 5-15% of the general population and is associated with increased morbidity from cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is a parameter of arterial stiffening and a good independent predictor for the presence of coronary artery disease.

Differences in ultrasound-derived arterial wall stiffness parameters and noninvasive blood pressure between Friesian horses and Warmblood horses [PDF]

, 2020
Background: Aortic rupture is more common in Friesians compared to Warmbloods, which might be related to differences in arterial wall composition and, as such, arterial wall stiffness (AWS).

A Bioimpedance Measurement System for Pulse Wave Analysis [PDF]

arXiv, 2019
The morphology and velocity of the pulse wave in the arteries provide meaningful information about the cardiovascular system. Nowadays, the pulse wave is usually acquired using common blood pressure cuffs at the extremities. This work describes a new measurement device which detects changes in bioimpedance due to the pulse wave.
