Using alpha-ketoglutarate to improve outcomes in patients with abdominal aortic aneurysms

The Intervention Effect Of Alpha-Ketoglutarate On Abdominal Aortic Aneurysm Progression and Rupture: A Prospective, Randomized Parallel Controlled Study Based On Large Cohorts

Not applicable Interventional RenJi Hospital · NCT04723888

This study is testing if a nutritional supplement called alpha-ketoglutarate can help people with abdominal aortic aneurysms feel better and reduce the risk of their condition getting worse.

What this trial studies

This project aims to determine if the nutritional supplement alpha-ketoglutarate can enhance outcomes for patients with abdominal aortic aneurysms (AAAs) measuring 39-49 mm in diameter. The study will involve oral administration of the supplement, which is known for its role in energy metabolism and is commonly used by athletes. Participants will be monitored for up to five years to assess the impact on AAA progression and rupture risk. The research seeks to establish a prediction model for AAA rupture risk in an elderly cohort.

Who should consider this trial

Good fit: Ideal candidates are Han nationality individuals aged 50 and older with an infrarenal AAA of 39-49 mm in diameter.

Not a fit: Patients with previous aortic surgery, known aortic dissection, or severe infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel method to slow the progression of abdominal aortic aneurysms and reduce the risk of rupture.

How similar studies have performed: While the use of alpha-ketoglutarate in this context is novel, its application in other metabolic and aging-related studies has shown promising results.
