26 Δεκ 2019 · In clinical practice, PWV is most commonly calculated as PWV=ΔL/ΔT, with ΔL the distance between 2 measuring sites, and ΔT the time it takes for the arterial pulse to travel from the proximal to the distal measuring site. 16 With the aorta being the major elastic vessel in the body, aortic PWV (or even PWV in segments of the aorta) likely ...
1 Φεβ 2002 · A simplified model of arterial elasticity has been used in many studies in which measurements are confined to the circumferential direction, and elastic non‐linearity is treated by defining incremental elastic properties over a limited region of the stress strain curve that is taken to be linear (for instance, that corresponding to the part ...
the elastic properties, particularly of large arteries, are impaired in the presence of cardiovascular disease and risk factors such as cigarette smoking, hypertension, diabetes and ageing. Evidence is also emerging that treatment of these risk factors
4 Μαΐ 2021 · An arterial wall has both elastic and viscous characteristics, and pathological and degenerative changes in the wall tissue affect the viscoelastic behavior of the artery wall. The arterial viscoelasticity may provide useful information regarding the development and progression of arterial diseases.
1 Αυγ 2018 · Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries.
1 Ιαν 2022 · It is clear that the complex behavior of arterial tissue cannot be described by the linear elasticity theory with the Young modulus as single material parameter.
1 Ιαν 2019 · Many important aspects of the mechanical behaviour of arterial tissue can be treated on the basis of elasticity theory, and the focus of the article is therefore on the constitutive modelling of the anisotropic and highly nonlinear elastic properties of the artery wall.
