Blood test to safely rule out aortic emergencies
Part of Heart & circulation clinical trials.
This study tests whether a simple blood test (D-dimer) combined with a risk score can safely identify patients who do not have a life-threatening tear in the aorta (the main artery from the heart). If it works, it could help doctors avoid unnecessary imaging scans and get patients diagnosed faster.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You went to the emergency room with sudden chest, abdominal, or back pain that started within the last 2 weeks, or fainting, or signs of reduced blood flow to your limbs or brain
- Your emergency room doctor thinks a tear in your aorta is possible based on your symptoms
- You have not already been diagnosed with an aortic tear before this emergency room visit
- You did not come to the hospital because of trauma or injury
- You are able and willing to complete the full blood test and evaluation

This study is testing a new way to quickly diagnose a tear or blood clot in the aorta (the main artery from the heart) by looking at a special score. If you have sudden chest, back, or belly pain, this trial may help find the cause faster.
This study tests whether an “add-on” anti-inflammatory approach can help after surgery for certain problems affecting the aorta (the body’s main artery) soon after symptoms begin. It may be designed to reduce inflammation-related complications in people who are treated quickly and can join follow-up.
This study tests an ultrasound screening at the ER to look for a bulge in the chest's main artery (aortic aneurysm) in people with high blood pressure. Early detection could help prevent a life-threatening rupture.
This trial compares two surgical methods for repairing the main artery (aorta) after a tear (dissection) that starts in the upper chest. One method replaces part of the aorta, and the other adds a stent. The goal is to find which approach works better for patients.
This study collects medical information and blood-test timing data to learn how to diagnose aortic dissection sooner and predict outcomes. It may help doctors better plan care for people with suspected or confirmed aortic dissection.
This trial uses artificial intelligence to help choose the best emergency surgery for people with a sudden tear in the main artery of the body (acute aortic dissection). It aims to improve outcomes by matching the treatment to each patient's specific condition.
