What this trial studies

This prospective randomized controlled trial aims to evaluate the quality of life and effectiveness of treatment in 80 patients diagnosed with unilateral primary aldosteronism. Participants will be randomly assigned to receive either surgical treatment through unilateral adrenalectomy or medical treatment with eplerenone. The study seeks to address the limited comparisons between these two treatment approaches, particularly focusing on cardiovascular outcomes and overall health care consumption. By confirming unilateral disease through adrenal venous sampling, the trial will provide valuable insights into the best treatment options for this condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with confirmed unilateral primary aldosteronism who are suitable for surgical treatment.

Not a fit: Patients who are unwilling to undergo surgery or have impaired renal function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide clearer guidance on whether surgery or medication is more effective for patients with unilateral primary aldosteronism.

How similar studies have performed: While studies comparing surgical and medical treatments for primary aldosteronism are limited, recent meta-analyses suggest that surgical treatment may lead to better cardiovascular outcomes.
