Lipid Profile in Primary Aldosteronism: Cross-Sectional and Post-Treatment Analyses

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Metabolic Disorders

Background:

• Primary aldosteronism (PA) and essential hypertension (EH) have debated impacts on lipid metabolism.
• Previous studies report inconsistent findings regarding PA's effect on lipid profiles.

Purpose of the Study:

• To clarify the relationship between PA and lipid metabolism.
• To compare lipid profiles in PA versus EH patients.
• To analyze lipid changes longitudinally after PA treatment.

Main Methods:

• Retrospective study of 112 PA patients and 115 EH controls.
• Collected sociodemographic, clinical, and biochemical data, including lipid profiles.
• Performed 1-year follow-up analysis for PA patients post-treatment (adrenalectomy or medical management).

Main Results:

• Initially higher triglyceride levels in PA patients without lipid-lowering therapy, which disappeared after adjustments.
• Baseline aldosterone levels >200 pg/mL correlated with lower triglyceride levels.
• Adrenalectomy in PA patients led to a significant 1-year increase in triglyceride levels.
• Estimated glomerular filtration rate significantly declined 1 year after PA treatment.

Conclusions:

• Aldosterone's association with triglyceride levels is complex and requires further investigation.
• PA treatment can impact lipid profiles and renal function.
• Prospective studies are needed to confirm these findings.
