Abstract

Aldosterone exerts cardiovascular effects by influencing epithelial fluid and electrolyte excretion, and thus blood volume and pressure. Mineralocorticoid receptors (MR) are found in epithelial and non-epithelial tissues (vessel walls, heart, brain), with high affinity for aldosterone and physiological glucocorticoids cortisol and corticosterone. MR blockade by spironolactone or eplerenone favorably affects cardiovascular outcomes. In some situations (primary aldosteronism, experimental mineralocorticoid administration) activation of cardiovascular MR reflects aldosterone levels inappropriate for salt status. In others (heart failure, essential hypertension) aldosterone and Na(+) status are often normal pretreatment; cardiovascular MR may thus be activated by normal glucocorticoid levels after tissue damage and reactive oxygen species generation. Therefore, although unilateral adrenalectomy is preferred therapy for unilateral aldosterone-producing adenoma or hyperplasia, MR blockade may be useful in cardiovascular diseases where aldosterone levels are normal.
