the elastic properties, particularly of large arteries, are impaired in the presence of cardiovascular disease and risk factors such as cigarette smoking, hypertension, diabetes and ageing. Evidence is also emerging that treatment of these risk factors
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.
Arterial Elasticity as Part of a Comprehensive Assessment of Cardiovascular Risk and Drug Treatment. Jay N. Cohn, Daniel A. Duprez, Gregory A. Grandits. Abstract—Early cardiovascular disease can be identified in asymptomatic individuals by noninvasive evaluation of functional and structural abnormalities of the vasculature and heart.
1 Ιαν 2008 · PDF | The aim of this paper is to provide a study of different models of the mechanical non-linear stress-strain behaviour of arteries. | Find, read and cite all the research you need on...
21 Ιουν 2024 · The elastic recoil of the vascular wall helps to maintain the pressure gradient that drives the blood through the arterial system. An elastic artery is also known as a conducting artery, because the large diameter of the lumen gives it a low resistance and enables it to accept a large volume of blood from the heart which is conducted to smaller ...
1 Φεβ 2002 · To calculate this quantity, which is equivalent to ‘Young's modulus’ as defined in Table 1 of the Mackenzie review, one must determine pressure, diameter and wall thickness over the chosen range of pressures. It may be regarded as a measure of the stiffness of the vessel wall material.
The calculations of arterial compliance, elastic modulus, augmentation pressure, stiffness and intima—media thickness may help to identify the role of each mechanism if they are based on high-tech measurements of arterial wall. The role of nervous regulation of blood vessel’s tone in this process is not clear.
