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.
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.
2 Μαΐ 2005 · PDF/EPUB. Abstract. Early cardiovascular disease can be identified in asymptomatic individuals by noninvasive evaluation of functional and structural abnormalities of the vasculature and heart. These abnomalities are usually a consequence of endothelial dysfunction.
Elastic fibers provide reversible elasticity to the large, elastic arteries. This allows the aorta to deform elastically under an applied hemodynamic load, with no permanent deformation and no energy dissipation when the load is removed.
Arterial elasticity was measured as carotid-femoral pulse wave velocity (cfPWV) and endothelial function was measured as digital reactive hyperemia index (RHI).
2 Φεβ 2018 · Insuffi-ciency of elastin or disorganization, improper assembly, frag-mentation, and biochemical modifications of elastic fibers change the passive mechanical behavior of the large arteries and affect cardiovascular mechanics at multiple length scales.
1 Φεβ 2002 · When measuring PWV to determine arterial elasticity, information about the shape of the pulse wave is, perforce, discarded. If this is not done the ‘true’ wave velocity cannot be derived, and false values of elasticity will result.
