NCT04723888

Brief Summary

The objective of this project is to define whether nutritional supplement (oral administration with alpha-ketoglutarate) capable of filling-up the citric acid cycle (anaplerotic therapy) can improve outcomes in patients with an abdominal aortic aneurysm of 39-49 mm in diameter on ultrasound imaging. Alpha-ketoglutarate is commonly used as a nutritional supplement specially by athletes to increase muscle strength. They can be mixed with formula or other foods. Subjects will be followed for up to 5 years.
