Hello and welcome to JustAnswer,
the reality is that there does appear to be SOME association between having creased earlobes and developing heart disesase such as a heart attack.
this has been known for twenty years or so....
BUT, it is not to say that everyone with creased earlobes will develop heart disease... it simply means it is one of many factors to consider when evaluating patients, particularly for heart issues.
much more important are the top five risk factors..... a blood relative with a heart attack before 50 years old, high cholesterol, diabetes, high blood pressure, and smoking.
