Analysis demonstrates how coronary geometry and hemodynamics affect shear stress in arteries, suggesting risks for plaque rupture.
Key Points
Higher blood viscosity and density from increased hematocrit raised shear stress levels significantly, impacting plaque health.
CFD simulations indicated that geometric variations in arterial structure caused substantial changes in shear stress distribution on the endothelial wall.
Stenosis locations and arterial tapering altered shear stress patterns, challenging traditional measures of ischemic risk assessment.
WSS values reaching over 30 Pa highlight the critical role of geometric and hemodynamic factors in cardiovascular health management.
