Investigation of haemodynamic markers for stenosis development

Different haemodynamic markers for stenosis development are considered, assessed and compared. A recently proposed numerical approach is employed, where stenosis development is modelled based on the local haemodynmaic conditions at the artery wall, determined using the lattice Boltzmann method. A range of haemodynamic markers, commonly associated in the literature with the progression of atherosclerosis were considered. In was observed that using the oscillatory shear index, which is related to the wall shear stress oscillating from its mean direction, did not produce a realistic stenosis development. The other markers produced stenosis growth comparable with observations from the literature.
