Official Title: Cardiovascular Evaluation of a Rare Condition With Hyperaldosteronism Without Hypertension: PHA 1
Brief Summary: Vascular and cardiac alterations are associated with aldosterone effects are evidenced in experimental models and aldosterone receptor blockade is of clear benefit in cardiac disease (heart failure). The study aims at assessing vascular and cardiac alterations in adults with a chronic increase in circulating aldosterone without hypertension. The investigated population will be patients with a rare disease, pseudohypoaldosteronism type 1, due to heterozygous inactivating mutations of the mineralocorticoid receptor.
