Pulse Wave Velocity (PWV) Test for Arterial Stiffness - Viasonix
Pulse wave velocity (PWV) is the velocity at which the blood pressure pulse propagates through the circulatory system, usually an artery or a combined length of arteries. PWV is used clinically as a measure of arterial stiffness and can be readily measured non-invasively in humans, with measurement of … See more The theory of the velocity of the transmission of the pulse through the circulation dates back to 1808 with the work of Thomas Young. The relationship between pulse wave velocity (PWV) and arterial wall … See more PWV intrinsically varies with blood pressure. PWV increases with pressure for two reasons: 1. Arterial compliance ( 2. Volume ($${\displaystyle V}$$) … See more Clinical methods Clinically, PWV can be measured in several ways and in different locations. The 'gold standard' … See more Since the wall thickness, radius and incremental elastic modulus vary from blood vessel to blood vessel, PWV will also vary between vessels. Most measurements of PWV represent an average velocity over several vessels (e.g. from the See more A range of invasive or non-invasive methods can be used to measure PWV. Some general approaches are: Using two simultaneously measured pressure waveforms PWV, by definition, is the distance traveled ( See more • Arterial stiffness • Blood pressure • Compliance (physiology) See more WebMay 4, 2024 · A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in … shippensburg university president
