The presence of atherosclerotic plaques has been shown to be closely related to the vessel
geometry. Studies on postmortem human arteries and on the experimental animal show …

Cardiovascular disease is the primary cause of morbidity and mortality in the western world.
Complex hemodynamics play a critical role in the development of atherosclerosis and the …

In addition to biochemical factors, hydromechanical influences are responsible for atherogenesis
and deposits of blood platelets at bends and bifurcations of human arteries. Hence the …

Measurements and numerical calculations of laminar flow in a plane 90 bifurcation are
