How to Explore an Endocrine Cause of Hypertension

Area of Science:

• Endocrinology
• Nephrology
• Cardiology

Background:

• Hypertension (HTN) is a prevalent global health issue, with 10-15% of cases being secondary HTN due to identifiable causes.
• Endocrine disorders, particularly adrenal conditions, are frequent contributors to secondary HTN.
• Early detection of secondary HTN is crucial for managing uncontrolled blood pressure and accessing specific treatments.

Purpose of the Study:

• To review and highlight the importance of exploring endocrine causes of hypertension.
• To focus on the diagnostic approaches for primary aldosteronism (PA) and pheochromocytoma and paraganglioma (PPGL).

Main Methods:

• This review focuses on the diagnostic strategies for endocrine hypertension.
• Emphasis is placed on primary aldosteronism and pheochromocytoma/paraganglioma.
• Discussion includes screening and exploration of patients at risk for secondary HTN.

Main Results:

• Primary aldosteronism is the most common endocrine cause of secondary HTN, potentially affecting up to 10% of hypertensive patients.
• Cushing syndrome and pheochromocytoma/paraganglioma are rarer causes of secondary HTN (<0.5% of patients).
• Timely diagnosis of secondary HTN can lead to curable or treatable conditions and better blood pressure control.

Conclusions:

• Screening for endocrine causes of HTN, especially PA and PPGL, is essential for effective patient management.
• Understanding and exploring these conditions can significantly improve outcomes for hypertensive patients.
• Physicians should prioritize the investigation of secondary HTN in at-risk individuals.
