[Current opinion on primary aldosteronism]

In recent years, a greater interest has been focused on primary aldosteronism (PA), which shows a higher prevalence rate than previously thought. The consequences of PA are life threatening such as a refractory hypertension with serious cardiovascular damages.The evaluation of a suspected PA should follow a step-by-step approach (screening test, then confirmatory test and, in some cases, adrenal venous sampling). This protocol may seem tedious, but it allows an accurate etiologic diagnosis that leads to an appropriate therapy with better blood pressure control,improvement of quality of life, and, in some cases even,cure of hypertension.
