Figure 2. Coronary perfusion pressure values reported as a percentage of coronary vascular bed contraction with increasing doses of acetylcholine (Ach) in the four treatment groups (SHAM, TAMOX, OVX, and OVX+TAMOX; for abbreviations, see legend to Table 1). Data are reported as means ± SEM (N = 7 rats in each group). *P < 0.01 compared to the SHAM group; ^†P < 0.01 compared to the OVX group (ANOVA followed by the Tukey post hoc test).
