Abstract

Primary aldosteronism (PA) is a known cause of hypertension. In the kidney, aldosterone promotes sodium and water reabsorption, increasing the intravascular volume and blood pressure (BP). In the cardiovascular system, aldosterone modifies endothelial and smooth muscle cell response, increasing cardiovascular risk in a blood pressure-independent way. Recently a high prevalence of PA (near to 10%) in hypertensive population, has been detected measuring plasma aldosterone/renin activity ratio (ARR) as screening test. This ratio increases along with the severity of the hypertensive disease. The diagnostic work up of PA should confirm the autonomy of aldosterone secretion from the renin-angiotensin system and should differentiate the clinical subtypes of the disease. These are idiopathic aldosteronism (IA) and aldosterone-producing adenoma (APA). Other causes are familial hyperaldosteronism (FH) type I (glucocorticoid-remediable aldosteronism), FH-II (non glucocorticoid-remediable aldosteronism), primary adrenal hyperplasia and adrenal carcinoma. This article reviews the prevalence, diagnosis and treatment of PA and also the clinical, biochemical and genetic characteristics of its different subtypes.
