This involves the aorta\u2014the main artery carrying blood from the heart to the rest of the body\u2014bulging or swelling, risking a rupture.\u00a0<\/p>\n
Ruptures in the blood vessel are often fatal due to severe internal bleeding, unless treated rapidly with emergency surgery.\u00a0<\/p>\n
In a video on TikTok<\/a> that has so far amassed over 230,000 views, Dr Whittington told his followers: ‘Hold up your palm and try and stretch your thumb across as far as you can. Does it stop about there?\u00a0<\/p>\n ‘Or does it extend pass your palm like these? If it does that is a positive thumb-palm test.’<\/p>\n If your thumb extends past your palm this could mean your connective tissues are ‘very stretchy’, he said, indicating that the same stretchiness applies to the tissues in the arteries, meaning a high chance of swelling or bulging.<\/p>\n He went on to detail a 2021 study, published in the American Journal of Cardiology, which found 60 per cent of people with known aortic aneurysms had a positive palm-thumb test.<\/p>\n @drjoe_md<\/a> <\/p>\n Can your thumb predict a hidden heart problem? \ud83e\udee3 The \u201cthumb-to-palm\u201d test was linked to a higher risk of ascending aortic aneurysm in a Yale study, almost 60% of patients with aneurysms had a positive result. But before you panic, this doesn\u2019t mean you have one. It\u2019s just one potential sign of stretchy connective tissue, which could also mean a stretchy aorta. If your thumb crosses your palm, especially with a family history of heart issues or connective tissue disorders, talk to your doctor. Flexibility is great\u2026 just not in your arteries. \ud83d\ude05 #hearthealth<\/a> #ehlersdanlossyndrome<\/a> #connectivetissuedisorder<\/a> #healthtips<\/a> <\/p>\n \u266c original sound – Dr. Joe, M.D. \ud83e\ude7a<\/a> <\/p><\/blockquote>\n Here is the test: Hold your hand up as if you’re telling someone to stop (1). With your palm flat, stretch your thumb as far as you can across it, towards your little finger. If your thumb reaches the middle of the palm (2) that is normal. However, if it stretches past the edge of your hand (3), researchers say this may be a sign of an aortic aneurysm and you should get it checked<\/p>\n The researchers gave the test to 305 patients underdoing cardiac surgery for a variety of disorders, including aortic aneurysms.\u00a0<\/p>\n While the majority of aneurysm patients do not manifest a positive thumb-palm sign,, patients who did have a positive test had a high likelihood of harboring an aneurysm.<\/p>\n It’s estimated that around 5,000 people in the UK die from\u00a0aorta-related problems every year, with aneurysms and dissections being the leading causes.<\/p>\n While many aneurysms don’t cause symptoms until they rupture, doctors may spot them during routine test and offer\u00a0treatments to prevent damage such as blood pressure medication.\u00a0<\/p>\n Those that do cause symptoms tend to trigger pain in the chest, neck, and\/or back; swelling of the head, neck and arms; coughing, wheezing, shortness of breath, or coughing up blood.\u00a0<\/p>\n But those with a positive palm-thumb test, ‘should not freak out’, said Dr Whittington.<\/p>\n ‘It’s worth bringing it up with your doctor so they can diver deeper into any sort of connective tissue disorders.’<\/p>\n \u00a0There are over 200 disorders that impact connective tissue, but there are different types.<\/p>\n In a study published in the American Journal of Cardiology, found 60% of people with known aortic aneurysms had a positive palm-thumb test<\/p>\n These include genetic disorders like Ehlers-Danlos syndrome, autoimmune disorders such as lupus and cancers like some types of soft tissue sarcoma.<\/p>\n The three most common aortic-related connective tissue disorders are Marfan Syndrome, Ehlers-Danlos Syndrome (EDS) and Loeys-Dietz Syndrome.<\/p>\n In the UK, over 18,000 people<\/a>\u00a0are affected by Marfan syndrome, although it is believed to remain undiagnosed in many people.<\/p>\n Experts estimate<\/a>\u00a0nearly half of people who have the condition don’t know it, so knowing the signs can save lives.<\/p>\n It can cause symptoms like heart palpitations, eye pain, shortness of breath and vision changes like astigmatism.<\/p>\n It can affect other parts of the body giving physical features like long and narrow face, limbs that seem too long for the rest of the body, and crowded teeth.<\/p>\n Those with this condition are at up to a 250 times greater risk of aortic dissection, a tear or rupture between layers of the aortic wall, than the general population.<\/p>\n EDS is a group of inherited connective tissue disorders affecting the skin, joints and blood vessels.<\/p>\n The thumb test will indicate if a person is harbouring an aortic aneurysm \u2014 an abnormal bulge in the wall of the major blood vessel that can prove fatal if undetected<\/p>\n \u00a0It is estimated there are anywhere between 135,000 and 300,000 people in the UK with the condition.<\/p>\n The most common type of EDS is hypermobile EDS<\/a>\u00a0(hEDS), which is thought to be underdiagnosed.<\/p>\n![\"Here](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/06\/43464343-14794733-Here_is_the_test_Hold_your_hand_up_as_if_you_re_telling_someone_-a-2_1749486059550.jpeg\")
