Polygenic Risk Scores for Prediction of Subclinical Coronary Artery Disease in Persons Living With HIV: The Swiss HIV Cohort Study

Jacques Fellay, Christian Axel Wandall Thorball

Background. In people living with human immunodeficiency virus (HIV) (PLWH), individual polygenic risk scores (PRSs) are associated with coronary artery disease (CAD) events. Whether PRSs are associated with subclinical CAD is unknown. Methods. In Swiss HI ...

Considerations for analysis of endothelial shear stress and strain in FSI models of atherosclerosis

Lydia Aslanidou, Fotios Savvopoulos

Atherosclerosis is a lipid driven chronic inflammatory disease that is characterized by the formation of plaques at predilection sites. These predilection sites (side branches, curved segments, and bifurcations) have often been associated with disturbed sh ...

The effect of left ventricular contractility on arterial hemodynamics: A model-based investigation

Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou

Ventricular-arterial coupling is a major determinant of cardiovascular performance, however, there are still inherent difficulties in distinguishing ventricular from vascular effects on arterial pulse phenotypes. In the present study, we employed an extens ...

A 1D computer model of the arterial circulation in horses: An important resource for studying global interactions between heart and vessels under normal and pathological conditions

Nikolaos Stergiopoulos, Patrick Segers

Arterial rupture in horses has been observed during exercise, after phenylephrine administration or during parturition (uterine artery). In human pathophysiological research, the use of computer models for studying arterial hemodynamics and understanding n ...

Large eddy simulations for blood dynamics in realistic stenotic carotids

Alfio Quarteroni, Christian Vergara

In this paper, we consider large eddy simulations (LES) for human stenotic carotids in presence of atheromasic plaque, a pathological condition where transitional effects to turbulence may occur, with relevant clinical implications such as plaque rupture. ...

Assessment of shear stress related parameters in the carotid bifurcation using mouse-specific FSI simulations

Bram Trachet, Patrick Segers

The ApoE(-/-) mouse is a common small animal model to study atherosclerosis, an inflammatory disease of the large and medium sized arteries such as the carotid artery. It is generally accepted that the wall shear stress, induced by the blood flow, plays a ...

The influence of anesthesia and fluid-structure interaction on simulated shear stress patterns in the carotid bifurcation of mice

Bram Trachet, Patrick Segers

Background: Low and oscillatory wall shear stresses (WSS) near aortic bifurcations have been linked to the onset of atherosclerosis. In previous work, we calculated detailed WSS patterns in the carotid bifurcation of mice using a Fluid-structure interactio ...

Fluid-structure interaction simulations of cerebral arteries modeled by isotropic and anisotropic constitutive laws

Alfio Quarteroni, Simone Deparis, Luca Dede', Paolo Tricerri, Adélia Sequeira

This paper considers numerical simulations of fluid-structure interaction (FSI) problems in hemodynamics for idealized geometries of healthy cerebral arteries modeled by both nonlinear isotropic and anisotropic material constitutive laws. In particular, it ...

Vulnerable Plaque Detection and Quantification with Gold Particle-Enhanced Computed Tomography in Atherosclerotic Mouse Models

Bram Trachet, Patrick Segers

Recently, an apolipoprotein E-deficient (ApoE(-/-)) mouse model with a mutation (C1039G+/-) in the fibrillin-1 (Fbn1) gene (ApoE(-/-)Fbn1(C1039G+/-) mouse model) was developed showing vulnerable atherosclerotic plaques, prone to rupture, in contrast to the ...

Dissecting abdominal aortic aneurysm in Ang II-infused mice: suprarenal branch ruptures and apparent luminal dilatation

Nikolaos Stergiopoulos, Jessica Sordet, Bram Trachet, Alessandra Piersigilli, Peter Modregger, Patrick Segers

Aims In this work, we provide novel insight into the morphology of dissecting abdominal aortic aneurysms in angiotensin II-infused mice. We demonstrate why they exhibit a large variation in shape and, unlike their human counterparts, are located suprarenal ...
