Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.
Personally, I believe the presence of an earlobe crease is more a sign of aging, which of course goes hand in hand with an increased chance of heart disease.
Regardless, we have far more accurate means to diagnose heart disease these days.

Here is a website that challenges the study:

There IS a higher chance of afib if you have lines or a red mark on the left side of your chest or your left arm near your biceps.
That is because people with afib are constantly checking their blood pressure and using portable ECGs to check their rhythm and heart rate.

I did a 23 and me DNA test and it said I have a 35 percent elevated risk of heart disease. Nobody in my entire family has had heart disease. Go figure...
