Summary

This study looks at whether people with an abdominal aortic aneurysm (a bulge in the main artery in the belly) have lower selenium levels than those without the condition. Researchers will compare 40 participants: half with the aneurysm and half without. The goal is to see if selenium deficiency is more common in aneurysm patients, which could help understand the disease better.

Who is studied

The study group comprises of 40 subjects. Twenty are cases, these are patients with AAA that was confirmed by radiology. The AAA was not treated by surgery or endovascular intervention. The are followed for the AAA by vascular surgery outpatient office. Controls are twenty persons without AAA, as confirmed by ultrasonography. They are followed by vascular surgery outpatient office for other vascular diseases. Both cases and controls are taken a blood sample, in which blood selenium level is established. Odds ratio will be calculated of having low than normal blood selenium levels in cases versus controls.
