Key result
Angle variation of jet flow at the throat of vulnerable stenosis predicts fibrous cap stress, which is proportional to the square of flow rate divided by cap thickness.
Angle variation of jet flow at the throat of vulnerable stenosis is proposed as a diagnostic index for predicting stress on the fibrous cap.
Deformation of vulnerable stenosis under pulsatile flow conditions and flow-induced stress acting on a fibrous cap are revealed to be proportional to the square of flow rate divided by fibrous cap thickness. Angle variation of jet flow at the throat of vulnerable stenosis is recommended as a diagnostic index for predicting the stress on the cap.
