Systems and methods for determining plaque vulnerability to rupture

摘要

In some embodiments, stress values for a diseased artery are obtained, stress ratios are determined from the obtained stress values, and a flow-structure interaction index is generated based upon the stress ratios as a function of a given plaque characteristic. In further embodiments, a plaque characteristic of a patient is determined, a patient's stress ratio is determined in relation to the flow-structure interaction index and the plaque characteristic, and the patient's stress ratio is compared to a critical stress ratio to determine whether the patient's stress ratio exceeds the critical stress ratio.
