Athletes at risk for sudden cardiac death

High school athletes represent the largest group of individuals affected by sudden cardiac death, with an estimated incidence of once or twice per week. Structural cardiovascular abnormalities are the most frequent cause of sudden cardiac death. Athletes participating in basketball, football, track, soccer, baseball, and swimming were found to have the highest incidence of sudden cardiac death. Screening of athletes prior to participation in competitive sports usually falls short of recommended guidelines. Poorly defined legislation and the absence of a national standard for sports physicals have contributed to inadequate health screenings of athletes. This article will describe the incidence and causes of sudden cardiovascular death in young athletes as well as guidelines intended to prevent this unfortunate problem.
