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.

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.
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.
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.
The review presented the physics of arterial elasticity followed by imaging-based lumen diameter and carotid intima-media thickness measurement, given the cardiac cycle’s spatial and temporal frames of the B-mode carotid ultrasound.
