Figure 1
Figure 1 Percentage changes in epicardial coronary artery diameter in response to acetylcholine infusion and nitroglycerin in Groups I and II. A: Greater changes in coronary artery diameter in response to acetylcholine infusion were observed in Group I (open circles) compared with Group II (black circles); B: Nitroglycerin-induced coronary dilation was similar between Groups I and II. Vertical bars represent SEM. ACh: Acetylcholine; NS: Not significant; NTG: Nitroglycerin.

Figure 2 Percentage changes in epicardial coronary artery diameter in response to acetylcholine infusion and nitroglycerin in Groups Ia and Ib. A: Greater changes in coronary artery diameter in response to acetylcholine (ACh infusion were observed in Group Ia (open circles) than those in Group Ib (gray circles); B: Nitroglycerin -induced coronary dilation was similar between Groups Ia and Ib. Vertical bars represent SEM. ACh: Acetylcholine; NTG: Nitroglycerin; NS: Not significant.
