We observed impaired outcomes in male compared to female mice, including mortality (†), reduction of LVEF and plasma TnT, with marked myocardial calcineurin activation and inflammation. Apical contractility was particularly blunted after EPI with elevated endsystolic left ventricular diameter, mimicking apical ballooning (dashed lines and arrows). Calcineurin inhibition by CsA or FK506 reduces the takotsubo phenotype in male and female mice. α/β-AR, α- or β-adrenergic receptor
