Figure 3 Comparative Analysis of Mean Percent Changes of Coronary Diameter in Response to Maximal Ach at 6 Months After Stent Implantation
Significant vasoconstrictions to maximal Ach infusion were observed in the segments distal to DES compared with those of BMS. Mean coronary diameter changes were similar between SES and PES. Changes in mean luminal diameter in response to Ach were greater at distal than proximal sites to stents in both the SES and PES groups. Open bars = SES; solid bars = PES; hatched bars = BMS. Abbreviations as in Figures 1 and 2.
