Arterial Stiffness and Hypertension [PDF]
Hypertension, 2014 Over the past decade, increased aortic stiffness has emerged as an important risk factor for target organ damage and cardiovascular disease events. Aortic stiffness can be assessed as pulse wave velocity (PWV), which is a measure of aortic wall stiffness, and pulse pressure (PP), which is affected by wall stiffness and the interaction between flow and ...

Non-invasive assessment by B-mode ultrasound of arterial pulse wave intensity and its modification during ventricular dysfunction [PDF]
arXiv, 2022 Arterial pulse waves contain clinically useful information: their intensity varies with cardiac performance, their speed (pulse wave velocity; PWV) depends on arterial stiffness and their reflection is affected by conduit artery tone. Here we demonstrate a novel method for non-invasively assessing wave properties.

Circulation Journal, 2010 Arterial walls stiffen with age. The most consistent and well-reported changes are luminal enlargement with wall thickening and a reduction of elastic properties at the level of large elastic arteries. Longstanding arterial pulsation in the central artery causes elastin fiber fatigue and fracture.

From arteries to boreholes: Steady-state response of a poroelastic cylinder to fluid injection [PDF]
Proceedings of the Royal Society A 473, 20160753 (2017), 2016 The radially outward flow of fluid into a porous medium occurs in many practical problems, from transport across vascular walls to the pressurisation of boreholes. As the driving pressure becomes non-negligible relative to the stiffness of the solid structure, the poromechanical coupling between the fluid and the solid has an increasingly strong impact

AGMN: Association Graph-based Graph Matching Network for Coronary Artery Semantic Labeling on Invasive Coronary Angiograms [PDF]
, 2023 Semantic labeling of coronary arterial segments in invasive coronary angiography (ICA) is important for automated assessment and report generation of coronary artery stenosis in the computer-aided diagnosis of coronary artery disease (CAD). Inspired by the training procedure of interventional cardiologists for interpreting the structure of coronary ...

Uric Acid and Arterial Stiffness
Therapeutics and Clinical Risk Management, 2020 Hyperuricemia is usually associated with hypertension, diabetes mellitus, metabolic syndrome and chronic kidney disease. Accumulating data from epidemiological studies indicate an association of increased uric acid (UA) with cardiovascular diseases ...

P5.19 STIFF ARTERIES, STIFF HEARTS?
Artery Research, 2013 Objectives: To examine the relationship between arterial stiffness and diastolic function in healthy normotensive subjects. Methods: For this study, 43 male (40±10 years) and 64 female (40±9 years) subjects were recruited. All were lifelong non-smokers, normolipidaemic, normoglycaemic and had normal 24-hour blood pressure responses (SBP\DBP <140\90).

Clinical and Experimental Hypertension, 2020 Intramyocellular lipid (IMCL) and extramyocellular lipid (EMCL) of ectopic fat in muscles are associated with arterial stiffness in normal-weight individuals. Furthermore, aerobic exercise training-induced changes in IMCL or EMCL content are related to a

Regulatory effect of gut microbes on blood pressure
Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 513-531, December 2022., 2022 The interaction between gut microbiota and hypertension, the genera which affect the blood pressure in taxonomic level, and the commonly used treatments to hypertension based on the gut microbes were summarized in this review. The increases of Lactobacillus, etc.
