Primary aldosteronism: challenges in diagnosis and management

Area of Science:

• Endocrinology
• Hypertension Management
• Cardiovascular Disease

Background:

• Primary aldosteronism (PA) is the leading cause of endocrine hypertension, affecting approximately 10% of all hypertensive individuals.
• A significant portion of PA cases (one-third) stem from aldosterone-producing adenomas.
• The cardiovascular and renal complications associated with PA are disproportionately severe relative to the level of hypertension.

Purpose of the Study:

• To highlight the critical need for accurate identification and treatment of primary aldosteronism.
• To address the diagnostic challenges faced by physicians in screening, interpreting results, and confirming PA.
• To emphasize the importance of subtype differentiation for guiding treatment decisions.

Main Methods:

• Screening patients using the aldosterone/renin ratio (ARR).
• Interpreting ARR results and selecting appropriate confirmatory diagnostic tests.
• Utilizing adrenal vein sampling for precise subtype differentiation.

Main Results:

• Primary aldosteronism is a common cause of secondary hypertension with significant morbidity.
• Diagnostic challenges exist in screening, interpretation, and confirmation of PA.
• Adrenal vein sampling is essential for differentiating PA subtypes.

Conclusions:

• Accurate identification and treatment of primary aldosteronism are essential for mitigating cardiovascular and renal morbidity.
• Overcoming diagnostic hurdles in PA screening and confirmation is critical for effective patient management.
• Tailoring treatment based on PA subtype leads to improved hypertension control and reduced associated health risks.
