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.
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...
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.
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 Φεβ 2018 · Elastin is an extracellular matrix (ECM) protein with a unique biochemical structure that provides entropic elasticity, allowing the large arteries to reversibly expand and relax with every cardiac cycle.
Elastin is an extracellular matrix (ECM) protein with a unique biochemical structure that provides entropic elasticity, allowing the large arteries to reversibly expand and relax with every cardiac cycle.
Functional and structural changes in the common carotid artery are biomarkers for cardiovascular risk. Current methods for measuring functional changes include pulse wave velocity, compliance, distensibility, strain, stress, stiffness, and elasticity.
