A research team from Yale University, led by Dr. John Elefteriades, has developed a quick and simple test that can help detect aortic aneurysms early. Aortic aneurysms are life-threatening expansions of the blood vessels. An aortic aneurysm is a bulge caused by weakened or damaged artery walls. It can form anywhere in the body, but most commonly occurs in the aorta or brain. If such a bulge suddenly ruptures, it can lead to internal bleeding, which is often fatal. Therefore, early detection is crucial.
Dr. Elefteriades’ team proposes the so-called «thumb test» that can indicate early signs of a possible aneurysm. The method is incredibly simple: the patient extends their hand with the palm facing upwards and moves the thumb as far as possible towards the palm. If the thumb protrudes beyond the edge of the open hand without the hand bending, this could indicate an increased risk of an aortic aneurysm.
Why does this test work? Scientists explain that excessive thumb mobility can be a sign of weak joints and overstretched bones — factors associated with connective tissue diseases throughout the body, including the aorta. To verify this hypothesis, Dr. Elefteriades’ team conducted tests on 305 patients who had previously undergone surgery for various heart conditions, including aortic aneurysms. The results showed that most patients with a diagnosed aneurysm were unable to move their thumb beyond the edge of their hand, while a significant percentage of the tested individuals were able to do so.
These findings led the researchers to conclude that a positive test result could indicate an increased likelihood of an aortic aneurysm. However, this test can only serve as a first precaution and does not replace a comprehensive medical examination. Experts recommend anyone who receives a positive test result to consult a cardiologist and undergo further examinations to accurately determine the actual health risk.
