High PSS and High Heterogeneity in PSS Is Associated With Increased Risk of Future MACE in VH-TCFA
(A) VH-IVUS and its associated band plot in a VH-TCFA. (B) PSS, variations in PSS and heterogeneity index of PSS is increased in VH-TCFAs with future MACE. (C) Incorporation of PSS and heterogeneity index in PSS allows the identification of VH-TCFAs that lead to MACE. *p < 0.05. HI = heterogeneity index; MACE = major adverse cardiovascular events; PSS = plaque structural stress; VH-TCFA = virtual-histology thin-cap fibroatheroma.
