Figure 1 Percentage changes in epicardial coronary artery diameter in response to acetylcholine and nitroglycerin infusion. A: Percentage changes in coronary artery diameter in response to low-dose acetylcholine infusion was significantly lower in the vasospastic angina (VSA) group than in the nonVSA group; B: Percentage changes in coronary artery diameter in response to nitroglycerin infusion were similar between groups. NS: Not significant.
