Intense workouts may be safe for heart patients: study

Moderate levels of exercise are often prescribed for people recovering from a heart attack or heart surgery, but a new study finds that pumping up workouts to high intensity levels might be a safe option too. Among 4,800 Norwegian heart patients, who racked up a combined total of over 170,000 hours of aerobic exercise, researchers found three cardiac arrests occurred during workouts and only one was fatal. The number was too small to say for sure that high impact workouts are just as safe as moderate ones, but they show the overall risk of exercise bringing on cardiac arrest is fairly low, according to the authors. "I think we're on the right track, but before we make it a standard recommendation, let's get our safety data," said Dr. Steven Keteyian, the director of preventive cardiology at Henry Ford Hospital in Michigan, who was not involved in the study
