Hello. im 19 and recently ive noticed a crease in my earlobe and im worried what it could be? is it associated with heart disease?

Hard to say,: There are lots of small studies on Ear Lobe Creases and Heart disease. Generally they say that the creases appear in older folks. However, most people in the US have a good chance of getting heart disease with or without ear lobe creases. If you don't want heart disease, then eat a low fat diet, don't smoke, and exercise, avoid moderate to heavy drinking as well. Dean Ornish, M. D. diet best.
