Key result
The sinus in stenosis-repaired carotid arteries demonstrated significantly lower wall shear stress (median 4.66 vs 14.30 Pa, p<0.001) and velocity compared to atherosclerosis-free areas, indicating a hemodynamic environment prone to atherosclerosis.
Why the study?
Do specific hemodynamic factors such as low wall shear stress and velocity correlate with the formation and progression of carotid atherosclerosis?
Population

Computational fluid dynamics with virtual vessel surface repairing demonstrates that areas of low wall shear stress, low velocity, and vortex formation are associated with the development and progression of carotid atherosclerosis.
Li et al. (2018) conducted an observational in Carotid Stenosis (n=28). Carotid sinus hemodynamics (stenosis-repaired) vs. Atherosclerosis-free areas was evaluated on Wall shear stress (WSS) in Pa (p=<0.001). The sinus in stenosis-repaired carotid arteries demonstrated significantly lower wall shear stress (median 4.66 vs 14.30 Pa, p<0.001) and velocity compared to atherosclerosis-free areas, indicating a hemodynamic environment prone to atherosclerosis.
