A research team from Yale University, led by Dr. John Elefteriades, has developed a quick and easy test that can help detect aortic aneurysms earlier. An aortic aneurysm is an abnormal enlargement of the blood vessel due to the weakening or damage of the artery wall. This condition can occur in various parts of the body, but is most often found in the aorta or brain. If this aneurysm suddenly ruptures, it can cause fatal internal bleeding. Therefore, early detection is very important.
Dr. Elefteriades’ team recommends the «Thumb Test», which can show early signs of a possible aneurysm. The method is very simple: a person should stretch their hand with the palm facing up, then bend their thumb as far as possible into the palm of the hand. If the thumb can pass the outer edge of the palm without bending the wrist, this could be an indication of aortic aneurysm risk.
Why does this test work? Scientists explain that the ability of the thumb to move like this could be a sign of overly flexible joint and bone weakness – a factor associated with connective tissue disorders throughout the body, including the aorta. To test this hypothesis, Dr. Elefteriades and his team conducted tests on 305 patients who had previously undergone heart surgery, including for aortic aneurysms.
The research results showed that most patients with aortic aneurysms could not bend their thumb past the edge of the palm, but a large number of participants were able to do so. This finding led researchers to conclude that if someone gets a positive result in this test, they are likely to have a higher chance of having an aortic aneurysm. However, even though it is beneficial as an early detection step, this test cannot replace a thorough medical examination. Experts advise anyone who gets a positive result in this test to consult with a heart specialist and undergo further examination to more accurately assess their health risk.
