Chen et al. (2025) studied Carotid atherosclerosis. Carotid plaque classification and bifurcation angle was evaluated on Hemodynamic parameters (TAWSS, OSI, ECAP) and plaque morphology. Larger carotid bifurcation angles and specific plaque locations critically modulated hemodynamics, with elevated upstream wall shear stress increasing rupture susceptibility.
