26 Δεκ 2019 · 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.
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.
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.
At rest and after cycle ergometry the elastic properties of the large arteries of limbs of healthy men were examined using an original non-invasive quantitative oscillometric method.
Elasticity in Arteries: A similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates.
An arterial wall has both elastic and viscous characteristics, and pathological and degenerative changes in the wall tissue afect the viscoelastic behavior of the artery wall. The arterial viscoelasticity may provide use-ful information regarding the development and progression of arterial diseases.
Sections. PDF (2 MB) Tools. Share. Abstract. 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.
