Figure 1 Representative Images of Conventional Intravascular Ultrasound and 2-Dimensional Integrated Backscatter Intravascular Ultrasound Color-Coded Maps of Coronary Artery Plaques in Patients With or Without MetS
(A) Patients with (+) metabolic syndrome (MetS); (B) patients without (–) MetS. The percentage of lipid area and the percentage of fibrous area were 46.1% and 50.1% in panel A, and 12.1% and 80.9% in panel B, respectively. Blue = lipid pool; green yellow = fibrous lesion; red = high signal lesion.

Figure 2 Representative Images of the 3-Dimensional Integrated Backscatter Intravascular Ultrasound in Patients With or Without MetS
(A) Patients with (+) metabolic syndrome (MetS); (B) patients without (–) MetS. The percentage of lipid volume was 52.7% in panel A and 23.0% in panel B. Blue and light blue = lipid pool; green and yellow = fibrous lesion; red = high signal lesion.

Figure 3 The Lipid-Rich Plaque Rate According to Increasing Numbers of MetS Components
The lipid-rich plaque rate was significantly associated with an increasing number of metabolic syndrome (MetS) components in the grouping. p = 0.002 by analysis of variance (ANOVA).
