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.
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.
Keywords Arterial stiffness . Compliance . Distensibility. Pulse wave velocity. Elastic modulus. The stiffness of the arterial wall is highly relevant to cardio-vascular disease for several reasons. Arterial stiffness is central in the pathogenesis of isolated systolic hypertension.
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.
An important reason may be the plethora of methods and devices claiming to measure arterial stiffness in humans. This brief review provides a concise overview of methods in use, indicating strengths and weaknesses.
21 Σεπ 2016 · We begin with a brief, general discussion of measurement and modeling of cardiovascular tissue viscoelasticity. We then review known viscoelastic behavior of arteries, veins, capillaries, blood...
1 Δεκ 2018 · Arterial stiffness is an important arterial phenotype and an excellent indicator of cardiovascular morbidity and mortality . It is an independent predictor of hypertension and cardiovascular diseases.
