Elevated cardiac tissue level of aldosterone and mineralocorticoid receptor in diastolic heart failure: Arch Intern Med ; These data suggest that aldosterone induces cardiac injury through activation of MRs and support the notion that MR blockade has beneficial effects on aldosterone-dependent cardiac injury, through mechanisms that cannot be simply explained by hemodynamic changes.
