Figure 4

Individual value bar graph of plaque burden in the patients with slow and normal contrast dye progression (subgroup of 32 patients). In the SCFph group, plaque burden was at least moderate, and all patients had a hidden athero; in contrast, in the control group, a large part of the subjects had no athero at all or minimal athero. By ROC analysis, a PB value < 38% had very high negative predictive value (100%) in ruling out hidden athero. Sens = sensitivity; Spec = specificity; IVUS = intravascular ultrasounds; LAD = left anterior descending coronary artery; LMCA = left main coronary artery.
