Recent findings SCD is rare but devastating in a young individual. The incidence of SCD in the young ranges from as low as 0.4 per 100 000 patient-years to as high as 13.4 per 100 000 patient-years. SCD occurs in all populations, not only in athletes. Summary Whether SCD is more common in athletes is the cause of continued debate stemming from conflicting data. Hypertrophic cardiomyopathy is the most common underlying cause of SCD in young athletes in most series; however, in nonathletic populations, the underlying causes of SCD are more varied. © 2011 Lippincott Williams & Wilkins, Inc.
