Screening and treatment of endocrine hypertension focusing on adrenal gland disorders: a narrative review.

Most cases of high blood pressure have no identifiable cause, termed essential hypertension; however, in approximately 15% of cases, hypertension occurs due to secondary causes. Primary aldosteronism (PA) and pheochromocytoma and paraganglioma (PPGL) are representative endocrine hypertensive diseases. The differentiation of endocrine hypertension provides an opportunity to cure and prevent target organ damage. PA is the most common cause of secondary hypertension, which significantly increases the risk of cardiovascular disease compared to essential hypertension; thus, patients with clinical manifestations suggestive of secondary hypertension should be screened for PA. PPGL are rare but can be fatal when misdiagnosed. PPGL are the most common hereditary endocrine tumors; therefore, genetic testing using next-generation sequencing panels is recommended. Herein, we aimed to summarize the characteristic clinical symptoms of PA and PPGL and when and how diagnostic tests and treatment strategies should be performed.
