Understanding the Neurovegetative Patterns in Patients with Thoracic Aortic Aneurysms

Investigation of the Neurovegetative Pattern in the Adult Population With Thoracic Aortic Aneurysms (AAT)

Observational IRCCS Policlinico S. Donato · NCT05703893

This study is trying to see how blood pressure and breathing patterns change in people with thoracic aortic aneurysms to better understand their risk of complications.

What this trial studies

This observational study aims to investigate the vagal features in patients with both syndromic and non-syndromic thoracic aortic aneurysms (TAA). Participants will undergo non-invasive monitoring of blood pressure and respiratory patterns while in supine and standing positions to assess their neurovegetative responses. The goal is to identify functional conditions that may help stratify patients based on their risk of aortic complications. By analyzing these patterns, the study seeks to understand how environmental stressors affect blood pressure and the structural integrity of the aortic wall.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18-65 with syndromic or non-syndromic thoracic aortic aneurysms who are either on pharmacological prophylaxis or newly diagnosed.

Not a fit: Patients with acute or chronic inflammatory diseases or those with significant thyroid dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved risk stratification and management strategies for patients with thoracic aortic aneurysms.

How similar studies have performed: While there is existing literature on the sympathetic nervous system's role in blood pressure regulation, this specific approach to studying neurovegetative patterns in TAA is novel and has not been extensively tested.
