Pulse Wave Velocity in Atherosclerosis [PDF]

open access: yesFrontiers in Cardiovascular Medicine, 2019
Early detection of subclinical atherosclerosis is important to reduce patients' cardiovascular risk. However, current diagnostic strategy focusing on traditional risk factors or using risk scoring is not satisfactory. Non-invasive imaging tools also have

Acute Changes in Carotid-Femoral Pulse-Wave Velocity Are Tracked by Heart-Femoral Pulse-Wave Velocity [PDF]

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Carotid-femoral pulse-wave velocity (cfPWV) is the reference standard measure of central arterial stiffness. However, it requires assessment of the carotid artery, which is technically challenging, and subject-level factors, including carotid

Pulse Wave Analysis and Pulse Wave Velocity for Fistula Assessment [PDF]

open access: yesKidney & Blood Pressure Research, 2020
Background/Aims: Pulse wave analysis (PWA) and pulse wave velocity (PWV) provide information about arterial stiffness and elasticity, which is mainly used for cardiovascular risk stratification.

Prediction of concrete strength using ultrasonic pulse velocity and artificial neural networks [PDF]

open access: yesUltrasonics, 2009
Ultrasonic pulse velocity technique is one of the most popular non-destructive techniques used in the assessment of concrete properties. However, it is very difficult to accurately evaluate the concrete compressive strength with this method since the ...

Venous pulse wave velocity [PDF]

open access: yesVascular Pharmacology, 2020
Central venous pressure and volume status are relevant parameters for the characterization of the patient's haemodynamic condition and for the management of fluid therapy however, their invasive assessment is affected by various risks and complications while non-invasive approaches provide only imprecise and subjective indications.

Resolving velocity ambiguity of two coded pulse in broad-band acoustic Doppler current profiler [PDF]

open access: yesMATEC Web of Conferences, 2019
Broad-band Acoustic Doppler Current Profiler (BBADCP) adopts short-sequence coded pulse to measure high velocity. Short-sequence coded pulse has large measurable velocity, so it is not easy to have velocity ambiguity.

Study on the effects of rupture directivity on seismic behaviour of hybrid skeletal systems of eccentrically braced frames with knee rods [PDF]

open access: yesJournal of Structural and Construction Engineering, 2020
The dual steel resistant skeleton is one of the functional structural systems for resisting against lateral forces induced by earthquakes that in addition to the enhanced ductility possesses high stiffness, dynamic stability, and redundancy.

Hemodynamic Data Analysis and Site of Measurement in Children and Adolescents

open access: yesArtery Research, 2020
Pulse wave velocity is a method of functional vascular evaluation. The gold standard is the carotid-femoral pulse wave velocity measurement. However, the software allows measurement among radial, carotid and femoral artery.
