Can nerve tests predict aortic aneurysm risks?

This study looks at how the nervous system works in adults with a rare condition called thoracic aortic aneurysm (a bulge in the chest's main artery). Researchers want to see if certain nerve patterns can help identify who is at higher risk for complications. About 139 participants will have their blood pressure and breathing measured while lying down and standing up. No treatments or drugs are tested—this is purely an observation to gather information.
