Health experts often say that your body offers telltale signs that something is wrong, such as changes in your skin and nails indicating serious internal illnesses. But even your earlobes could be sending you a crucial message about your cardiovascular health, according to a new study published in the American Journal of Medicine.
The condition, known as Frank’s sign, is a diagonal earlobe crease that was found to have a relationship to risk of stroke. The researchers, who are based in Israel, studied 241 patients who were hospitalized with a stroke and found that 79 percent had Frank’s sign.
Additionally, 66 of the patients who suffered the most common type of stroke, acute ischemic (where a blockage cuts off blood supply to the brain), had previously experienced a heart attack. In this group, almost 9 out of 10 had the Frank’s sign marker.
From these findings, researchers concluded that Frank’s sign could predict ischemic cerebrovascular events (strokes) and that patients with classical cardiovascular risk factors had the ear crease in higher numbers.
Frank’s sign is named after Sanders T. Frank, M.D., who discovered it in the 1970s while examining a patient with heart disease. The crease may signal poor blood supply to the earlobes, or could be a symptom of weakening in the blood vessels. It could also be related to aging.
