Contractile response to βAR stimulation and stress in cardiomyocytes and the influence of estrogen receptor agonists and antagonists. a Contractile responses to stress in male, sham, OVX, and OVX + E, in the presence or absence of estrogen receptor agonists and antagonists. b Corresponding Ca²⁺ transient amplitude in male, sham, OVX, and OVX + E in the presence or absence of estrogen receptor agonists and antagonists (n = 10 cells/7 mice). c Effect of ISO-stimulation (control) and Epi (stress) on cAMP in the presence or absence of estrogen receptor agonists and antagonists (n = 10 cells/7 mice). ^*P < 0.05, ^**P < 0.01, ^&&P < 0.01 vs control OVX. All data are presented as mean ± S.E.M
