Assessing the impact of adrenal artery embolization on blood vessel function in patients with primary aldosteronism

The Effect of Selective Adrenal Artery Embolism on Vascular Endothelial Function in Patients With Primary Aldosteronism Based on Brachial Artery Flow-mediated Relaxation

Observational Second Affiliated Hospital of Nanchang University · NCT05561361

This study is testing if a procedure called adrenal artery embolization can improve blood vessel function in people with primary aldosteronism compared to taking a medication called spironolactone.

What this trial studies

This observational study evaluates how superselective adrenal artery embolization affects vascular endothelial function in patients diagnosed with primary aldosteronism. Participants will undergo a two-week screening period to determine eligibility, after which they will be assigned to either the embolization group or the spironolactone therapy group based on their preferences and medical indications. The primary outcome will be measured through brachial artery flow-mediated relaxation, providing insights into the effectiveness of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with diagnosed primary aldosteronism and specific blood pressure criteria.

Not a fit: Patients with secondary hypertension or contraindications to spironolactone will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve vascular health and blood pressure management in patients with primary aldosteronism.

How similar studies have performed: While similar approaches have been explored, this specific intervention's impact on vascular function in primary aldosteronism is novel.
