Key result
Blood aldosterone levels in aldosterone-producing adenomas are more sensitive to ACTH than in bilateral hyperaldosteronism, making ACTH stimulation testing useful for prioritizing patients for adrenal venous sampling.
Why the study?
Does the ACTH stimulation test help differentiate aldosterone-producing adenoma from bilateral hyperaldosteronism in patients with primary aldosteronism?
Does the ACTH stimulation test help differentiate aldosterone-producing adenoma from bilateral hyperaldosteronism in patients with primary aldosteronism?

The ACTH stimulation test, particularly after dexamethasone suppression, is a useful non-invasive tool to help differentiate aldosterone-producing adenoma from bilateral hyperaldosteronism prior to adrenal venous sampling.
Primary aldosteronism (PA), one of the most frequent causes of secondary hypertension, is mainly composed of two major subtypes: aldosterone-producing adenoma (APA) and bilateral hyperaldosteronism (BHA)

Masakatsu Sone (2017) conducted a review in Primary aldosteronism (Aldosterone-producing adenoma). ACTH stimulation test was evaluated. Blood aldosterone levels in aldosterone-producing adenomas are more sensitive to ACTH than in bilateral hyperaldosteronism, making ACTH stimulation testing useful for prioritizing patients for adrenal venous sampling.
