Figure 2 Representative cross-sectional intravascular ultrasound images of matched arterial segments at baseline (left) and follow-up (right). At sites that underwent atheroma regression in response to infusions of reconstituted high-density lipoprotein cholesterol containing recombinant human apolipoprotein A-I Milano (top and middle panels), there was concomitant reduction in external elastic membrane (EEM) area with no change in the lumen size. At sites where there was no change in plaque area (bottom panels), there was no change in either the EEM or lumen.
