Athletic training and competition can increase the risk of sudden cardiac death in people with underlying heart disease, said the American Heart Association. The most common cause: hypertrophic cardiomyopathy, an abnormal growth of heart muscle fibers.

American Heart Association president Ralph L. Sacco, M.D., said in a press release: "We strongly encourage student-athletes and other participants in organized competitive sports to be screened with a careful history, including family history, and thorough physical examination."

In addition to more extensive health screenings for collegiate athletes, the AHA also recommends the placement of automated external defibrillators (AEDs) in venues where the high-risks sports are played.
