Evaluation and Management of Primary Hyperaldosteronism

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Hypertension Research

Background:

• Primary hyperaldosteronism is a prevalent and significant cause of hypertension.
• It is characterized by the adrenal glands producing too much aldosterone.
• Over 90% of cases stem from idiopathic adrenal hyperplasia or aldosterone-producing adenomas.

Purpose of the Study:

• To outline a diagnostic strategy for primary hyperaldosteronism.
• To emphasize the importance of subtype classification for treatment decisions.
• To clarify the role of imaging and adrenal vein sampling (AVS) in diagnosis.

Main Methods:

• A step-wise diagnostic approach is recommended.
• Screening at-risk populations is the initial step.
• Confirmatory testing follows positive screening, with subtype classification using imaging and AVS.

Main Results:

• The diagnostic pathway involves screening, confirmation, and subtype classification.
• Idiopathic adrenal hyperplasia and aldosterone-producing adenomas are the primary causes.
• Adrenal vein sampling (AVS) is crucial for subtype classification, with exceptions for specific patient groups.

Conclusions:

• A structured diagnostic approach is essential for primary hyperaldosteronism.
• Accurate subtype classification guides appropriate surgical or medical management.
• Imaging and AVS are key components of the diagnostic workup.
