Non-invasive Evaluation of Aortic Stiffness Dependence with Aortic Blood Pressure and Internal Radius by Shear Wave Elastography and Ultrafast Imaging [PDF]
IRBM, Elsevier Masson, 2018, 39 (1), pp.9-17, 2019 Elastic properties of arteries have long been recognized as playing a major role in the cardiovascular system. However, non-invasive in vivo assessment of local arterial stiffness remains challenging and imprecise as current techniques rely on indirect estimates such as wall deformation or pulse wave velocity.

Arterial Stiffness Preceding Diabetes
Circulation Research, 2020 Supplemental Digital Content is available in the text. Rationale: Previous studies on the relationship between diabetes and arterial stiffness were mostly cross-sectional. A few longitudinal studies focused on one single direction.

Uses of Arterial Stiffness in Clinical Practice.
Arteriosclerosis, Thrombosis and Vascular Biology, 2020 As far back as the ancient Egyptians and Greeks, physicians have observed and interpreted the arterial pulse to diagnose disease. In the last 20 years, advances in modern engineering have rendered quantitative pulse wave analysis widely available ...

Arterial Stiffness in Hypertension and Function of Large Arteries.
American Journal of Hypertension, 2020 BACKGROUND Arterial stiffness-typically assessed from non-invasive measurement of pulse wave velocity along a straight portion of the vascular tree between the right common carotid and femoral arteries-is a reliable predictor of cardiovascular risk in ...

Acute changes in arterial stiffness following exercise in healthy Caucasians and South Asians
Artery Research, 2015 Background: Arterial stiffness and exercise capacity are independent predictors of cardiovascular diseases. This study aims to establish the acute changes in arterial stiffness using applanation tonometry following sub-maximal exercise in Caucasians and ...

In vitro histomechanical effects of enzymatic degradation in carotid arteries during inflation tests with pulsatile loading [PDF]
Journal of the Mechanical Behavior of Biomedical Materials, 2020,
103, pp.103550, 2019 In this paper, the objective is to assess the histomechanical effects of collagen proteolysis in arteries under loading conditions reproducing in vivo environment. Thirteen segments of common porcine carotid arteries (8 proximal and 5 distal) were immersed in a bath of bacterial collagenase and tested with a pulsatile tension/inflation machine ...

Wrinkles in the opening angle method [PDF]
International Journal of Solids and Structures, 122 (2017) 189-195, 2020 We investigate the stability of the deformation modeled by the opening angle method, often used to give a measure of residual stresses in arteries and other biological soft tubular structures. Specifically, we study the influence of stiffness contrast, dimensions and inner pressure on the onset of wrinkles when an open sector of a soft tube, coated ...

Magnesium and Arterial Stiffness [PDF]
Hypertension, 2006 To The Editor: We read with interest the paper by S. Laurent et al1 dealing with structural and genetic bases of arterial stiffness. The authors reviewed data concerning the heritability of arterial stiffness and propose an integrated view of the structural and genetic determinants of arterial stiffness based on a candidate gene approach and recent ...

Determinants of arterial stiffness in COPD [PDF]
BMC Pulmonary Medicine, 2014 Cardiovascular morbidity and mortality is high in patients with chronic obstructive pulmonary disease (COPD) and arterial stiffness is a potentially modifiable risk factor with added predictive value beyond that obtained from traditional risk factors.
