A SPATIAL 3D SIMULATION OF THE HEMODYNAMICS OF THE ATHEROSCLEROTIC CORONARY ARTERY BY FEM

摘要

There is more and more evidence that hemodynamic factors play an important role in the development of the arterial atherogenesis, but even up to now, the specific role of the hemodynamic factors is not well understood yet, therefore further research work of revealing the biomechanical mechanism of atherosclerosis is helpful and necessary to learn its pathology and occurrence. To study the effect of the hemodynamic factors on the atherogenesis, a series of spatial 3D geometric models of coronary artery were built up. By FEM, the numerical simulation was carried out according to such models, many important hemodynamic variables, such as the tempo-spatial velocity field at every cross section of the artery, the pressure distribution, the secondary flow and the WSS (wall shear stress) at the specific areas were obtained, which will help understand the biomechanics of coronary atherosclerosis furtherly.
