Discussion

Analysis demonstrates altered wall shear stress in the left circumflex artery, suggesting improved cardiovascular event predictions.

The two-phase fluid-structure interaction model shows significant differences in wall shear stress compared to single-phase models.
During peak systole, the two-phase model produced a wall shear stress of 24.79 Pa, much lower than the single-phase predictions of 143.43 Pa.
Incorporating red blood cells as a phase in the model enhances understanding of stress distributions in coronary arteries.
This comprehensive biomechanical model could improve predictions related to cardiovascular health by accounting for blood components.

Jouneghani et al. (2025) studied this question.
