My guess is they are using "heart attack" as a general term. My boss at my previous job had a genetic disease that caused heart arrhythmia's frequently. They were not life threatening if handled in time, he had an internal defibrillator(?) that would trigger a shock to correct the problem in the worst case. Most of the time he would have someone drive him to the hospital (1-2 hours away) to have it reset in a controlled environment

Eventually he made several corrections to his lifestyle that reduced the number of attacks considerably and volunteered for several corrective procedures to fix the problem (He wanted his son to be able to live without the risks) last I heard he had the defibrillator removed after a surgery at the Mayo Clinic, diet changes (no alcohol), and improvement to his physique due to regular exercise (obesity increased the chances of attacks for his condition).
