Figure 4. Polarization properties in caps of culprit/target lesions.

Figure 4.

(A and B) Difference in birefringence (A) and depolarization (B) between patients with ACS/PR (88 cross-sections from 5 culprit lesions) and SAP (156 cross-sections from 8 target lesions). Fibrous caps in ACS/PR patients exhibited significantly lower birefringence compared to SAP patients. ACS = acute coronary syndrome, PR = plaque rupture, and SAP = stable angina pectoris.
