Figure 2 Comparative Analysis of Mean Percent Changes of Coronary Diameter in Response to Incremental Ach and Nitrate Infusion at 6 Months After Stent Implantation
Sites proximal and distal to DES showed a greater vasoconstriction in the DES group than in the BMS group or corresponding segments of the left circumflex artery (LCX) as a reference artery. Mean coronary diameter changes were similar in the SES and PES groups. Ach = acetylcholine; LAD = left anterior descending coronary artery; other abbreviations as in Figure 1.
