Summary

This study follows 320 people with small-to-moderate thoracic aortic aneurysms for up to 5 years. Researchers will track major complications like rupture or need for surgery, and look for factors such as high blood pressure or sleep problems that might speed up aneurysm growth. The goal is to better predict who is at risk and improve monitoring.
