Canadian research highlights the seemingly growing problem of undiagnosed heart disease in youth. Dr. Andrew Kahn, from the University of British Columbia, recently presented a study at the Canadian Cardiovascular Congress that analyzed the potential harm of exercise to heart health. 

Dr. Krahn's research dispels a myth that sudden cardiac death often takes place during rigorous physical activity. In fact, he found the majority of events (72 per cent) occurred at home.

Young athletes, then, who die suddenly, are more recognizable to the public, but are not the only sufferers. 

"This research gives us an idea of the scope of the problem -- there are almost 200 young people who die suddenly every year in Ontario. A good proportion of them have unrecognized heart disease. So the question is: How can we catch this before it happens?"

The Science Daily article goes on to explain that training in CPR and AED use, and a national screening program are good methods of prevention.
