Identifying Aortic Dissection in Patients with Chest Pain
Identification of Aortic Dissection Based on Pulse Oxygen and Ultrasound Doppler Waveforms
This study is trying to see if using special tests on the arms and legs can help doctors better identify aortic dissection in patients with chest pain.

What this trial studies
This observational study focuses on patients presenting with high-risk chest pain who have been identified through computed tomography angiography (CTA) as having aortic dissection. The study aims to validate the effectiveness of using extremity oximetry and Doppler waveforms to accurately identify this condition. By establishing a cohort of these patients, researchers will analyze the correlation between the non-invasive methods and the diagnosis of aortic dissection. The findings could enhance diagnostic accuracy and improve patient outcomes.
Who should consider this trial
Good fit: Ideal candidates are individuals experiencing high-risk chest pain who have undergone CTA.
Not a fit: Patients in shock, coma, or with severe peripheral vascular diseases may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to quicker and more accurate identification of aortic dissection, potentially saving lives.
How similar studies have performed: While there have been studies on non-invasive methods for diagnosing aortic dissection, this specific approach using extremity oximetry and Doppler waveforms is relatively novel.
