26 Δεκ 2019 · Figure 1. Top, the typical nonlinear relation between luminal pressure and area in large elastic arteries, explained by the progressive shift in load bearing from elastin to collagen fibers. Data translate into distensibility and pulse wave velocity (PWV) with the use of the Bramwell-Hill relation.
1 Μαΐ 2013 · The first techniques, developed to evaluate arterial stiffness, use indirect measurements such as pulse wave velocity or the analysis of variations in intra-arterial pressure and volume to estimate arterial stiffness.
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.
These results show that the elasticity of the arterial wall determined by means of its incremental modulus was strongly affected by blood viscosity (and therefore shear stress), probably due to the presence or absence of endothelium relaxing factors.
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
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 ...
2 Μαΐ 2005 · A panel of 10 tests, including small and large artery elasticity, has been used as the basis for a screening system that provides a score of 0 to 20 as a guide to the severity of disease. Using that Rasmussen score allows for stratification of patients into low, intermediate, or high risk for progression to cardiovascular morbid events.
