To answer the OP's question directly and succinctly, "No." I worry far more about being hit by some clown yakking or texting on the cellphone. I do not have any consistent family history of heart problems. Yes, I do know that people who live right, eat right, and exercise right are still known to have heart attacks, but many of them do have a genetic predisposition. We do the best with the hand we are dealt.
