Is 'Frank's sign' on ear related to increased risk of heart disease or stroke?
A deep diagonal crease on earlobe, called Frank’s sign, has been observed in some studies as a potential indicator of an increased risk for heart disease or stroke. Dr Swarup Swaraj Pal of Gleneagles Hospitals said that having this crease does not guarantee you will have a heart attack or stroke, nor does its absence mean you're in the clear.
