Heart attacks can and do happen in very fit people from plaque detaching from artery walls and blocking blood supply to the heart and hence oxygen. Plaque is related to diet and can happen in very fit athletes. (Years ago, the runner Jim Fixx advocated running as an activity that allowed you to eat anything with impunity. He died of a widowmaker as a marathon-fit athlete.)
