The study of vascular wall stiffness in patients with arterial hypertension depending on some factors of risk and associated clinical conditions [PDF]

open access: yesКардиоСоматика, 2019
Aim. To study the effect of gender, age, duration of disease and different forms of ischemic heart disease on the stiffness of the vascular wall in patients with arterial hypertension by determining the propagation velocity of the pulse wave.

Shock Wave Emissions of a Sonoluminescing Bubble

open access: yes, 1998
A single bubble in water is excited by a standing ultrasound wave. At high intensity the bubble starts to emit light. Together with the emitted light pulse, a shock wave is generated in the liquid at collapse time.

Blood pulse wave velocity measured by photoacoustic microscopy [PDF]

open access: yes, 2013
Blood pulse wave velocity (PWV) is an important indicator for vascular stiffness. In this letter, we present electrocardiogram-synchronized photoacoustic microscopy for in vivo noninvasive quantification of the PWV in the peripheral vessels of mice ...

Increased Pulse Wave Velocity in Subclinical Hypothyroidism [PDF]

open access: yesThe 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.

Study to Predict Vascular Dysfunctions in High Risk Young Adults- An Immediate Non-Invasive Investigation to Prevent Early Vascular Ageing [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Introduction: Normal vascular is associated with gradual change of vascular structure and function, resulting in increased arterial stiffening and decreased arterial compliance.

Aortic frequency response determination via bioimpedance plethysmography

open access: yes, 2019
Objective: Arterial stiffness is an important marker to predict cardio vascular events. Common measurement techniques to determine the condition of the aorta are limited to the acquisition of the arterial pulse wave at the extremities.

P1.14 PULSE WAVE VELOCITY AND KIDNEY DISEASE

open access: yesArtery Research, 2013
Increased arterial stiffness is one of the major alterations in arterial wall. It can be evaluated in non-invasively way by measuring the pulse wave velocity PWV in large arteries.

Method for in-situ nondestructive measurement of Young's modulus of plate structures [PDF]

open access: yes, 2003
A method for determining stiffness of a composite laminate plate entails disposing a device for generating an acoustical pulse against a surface of the plate and disposing a detecting device against the same surface spaced a known distance from the pulse-

P120 DETERMINANTS OF BRACHIAL-ANKLE PULSE WAVE VELOCITY

open access: yesArtery Research, 2018
It has been proven that aortic pulse wave velocity (aoPWV) the measure of arterial stiffness is a strong and independent predictor of both cardiovascular events and all-cause mortality.

Higher order dispersion in the propagation of a gravity wave packet [PDF]

open access: yes
To the first order of approximation, the complex amplitude of a wave packet in an anisotropic and dispersive medium is convected with the group of velocity. However, a gravity wave is a vector wave.
