Figure 3 Changes in angioscopic findings from baseline to follow-up. (A) A right coronary angiogram of a patient in the atorvastatin group. (B) Yellow plaque in a patient in the atorvastatin group at baseline. Yellow plaque (yellow score: 3) was observed in the mid-portion of the right coronary artery at baseline (arrow in A). The surface of this plaque was smooth, and a thrombus was not noted (disrupted score: 0). (C) White plaque in a patient in the atorvastatin group at follow-up. After treatment with atorvastatin, the yellow plaque changed into a completely white plaque. Both the yellow score and disrupted score were 0. (D) A right coronary angiogram of a patient in the comparison group. (E) Yellow plaque in a patient in the comparison group at baseline. Yellow plaque (yellow score: 1) was observed in the mid-portion of the right coronary artery at baseline (arrow in D). The surface of this plaque was smooth, and a thrombus was not noted (disrupted score: 0). (F) Yellow plaque in a patient in the comparison group at follow-up. After 12 months of follow-up without lipid-lowering medication, the yellow score had increased to 2, and the surface of this plaque had become irregular (disrupted score: 1).
