It's a tragic news story that often makes headlines a young, healthy, fit athlete suddenly collapses and dies of cardiac arrest while playing sports.
Dr. Andrew Krahn of the University of British Columbia, presenting a study at the 2012 Canadian Cardiovascular Congress about sudden cardiac death in Ontario, suggests this is a problem that warrants attention, but says don't blame the sports.
Reviewing coroners' reports, Dr. Krahn and a team of researchers found there were 174 cases of presumed sudden death in Ontario in 2008 in people aged two to 40 years.
Heart disease was present in 126 cases (72 per cent), 78 per cent of which was unrecognized. The majority of victims were male (76 per cent) between the ages of 18 and 40 (90 per cent).
With sudden cardiac death, people who seem to be perfectly healthy can die suddenly. Each year up to 40,000 Canadians die of sudden cardiac arrest. A significant proportion of these cases occur in otherwise healthy, young individuals.
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.
Only 33 per cent of events involving children/adolescents and just nine per cent of events in adults occurred during moderate or vigorous exercise.
"Put it this way: If you have a 13-year-old kid who is not the star athlete who dies at home watching TV, it doesn't make the news," said Dr. Krahn. "But if the same kid is a high school quarterback or hockey star, then it's covered."
Regardless of the location of the cardiac event, Dr. Krahn believes his research sheds some light on this issue.
"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 be
