  2. Mean values and SEM for systolic blood pressure (sysBP), heart rate (HR), rate-pressure product (RPP), flow in the left circumflex coronary artery (flow) relative to baseline 1 and change in coronary sinus oxygen saturation (SvO2) from baseline 1 at the different experimental levels (BL 1-3: baseline, ACh 1-3: intracoronary acetylcholine infusion/increasing doses, Ade 1-3: intracoronary adenosine infusion/increasing doses; detailed drug doses in the text). *: p < 0.05 vs. baseline (BL1).
