Are Ear Creases A Sign Of Heart Disease?

Not too long ago I was watching an episode of Dr. Oz. They were discussing if you have a prominent crease in your ear lobe and it is a sign of something. I think it had to do with your heart. I have good blood pressure, but slightly elevated cholesterol, which I am working on to reduce. Should I be concerned? I just recently had a physical and blood work, etc., which determined that I was in good health.
