Mineralocorticoid receptors and pathophysiological roles for aldosterone in the cardiovascular system

For almost 40 years since its discovery in 1953, the mineralocorticoid hormone, aldosterone, was considered to affect blood volume, and thus blood pressure, by its action to retain sodium at epithelial tissues. Over the past decade, direct effects of aldosterone on the heart and blood vessels, and on the cerebral control of blood pressure, have been established in experimental animals. Simultaneously, the incidence of primary aldosteronism in essential hypertension is now acknowledged to be 10-20%, rather than
