Ask the doctors. It's my understanding that as many as half the people who suffer heart attacks have "good" lipid profiles, decent diets, etc, but have a high-risk family history. You seem to imply in Heart Advisor that if these people have low cholesterol levels, eat properly and exercise, they have done everything they can do. I think this is misleading.
