A deep crease could be cause for concern
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.
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.
If you have a deep crease in your earlobe and are concerned about your cardiovascular health, talk with your doctor about risk factors to see if additional tests are warranted.
