Definition
Hyperaldosteronism is a clinical condition characterized by hypertension due to unregulated increase of aldosterone secretion, which in most of the cases is associated with hypokalemia. The increased secretion of aldosterone determines renal potassium excretion and reabsorption of sodium with consequent water retention and plasma volume expansion.
Clinical Features
Incidence
Primary hyperaldosteronism is the most frequent cause of secondary hypertension with an estimated incidence of 6–20% in adult patients with hypertension. The estimated prevalence is 5–10% of all patients with hypertension. The prevalence can reach 30% if the aldosterone to renin ratio is used as a screening method to detect the disease.
Age
The diagnosis of primary hyperaldosteronism is usually made in patients who are in the third to sixth decade of life.
Sex
The disease is two times more common in women than in men.
Site
Most cases of primary hyperaldosteronism are caused by...
