26 Δεκ 2019 · These arteries progressively lose their low-stretch bearing component, shifting load to stiffer matrix components (collagen). At the same time, arteries also lose some of their longitudinal elasticity and geometry, leading to elongation and increased tortuosity.
NAVBO Education Committee Webinar Series.Presented by Dr. Jessica Wagenseil on April 5, 2018: Elastic Fibers and the Mechanics of Maturing Arteries.
1 Απρ 2019 · Researchers pooled findings from 10 studies that measured people's daily step counts and their arterial stiffness, using a technique called pulse wave velocity. With every heartbeat, a wave of blood travels through the body's network of arteries.
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 Μαΐ 2005 · The goal of this preventive strategy is to improve the precision for early detection and treatment by identifying a marker or markers for early cardiovascular disease that could serve as a surrogate for disease progression, morbid events, and the response to therapy.
4 Ιουλ 2018 · To update and review novel insights into the mechanisms, measurements, and therapeutic approaches to arterial stiffness. Arterial (e.g., vascular) stiffness has been shown over time to prognosticate for cardiovascular and kidney outcomes.
1 Φεβ 2002 · A simplified model of arterial elasticity has been used in many studies in which measurements are confined to the circumferential direction, and elastic non‐linearity is treated by defining incremental elastic properties over a limited region of the stress strain curve that is taken to be linear (for instance, that corresponding to the part ...
