Sudden death (athletes)


It remains a difficult medical challenge to prevent the sudden cardiac death of athletes, typically defined as natural, unexpected death from cardiac arrest within one hour of the onset of collapse symptoms, excluding additional time on mechanical life support. (Wider definitions of sudden death are also in use, but not usually applied to the athletic situation.) Most causes relate to congenital or acquired cardiovascular disease with no symptoms noted before the fatal event. The prevalence of any single, associated condition is low, probably less than 0.3%, and the sensitivity and specificity of common screening tests leave much to be desired. The single most important predictor is fainting or near-fainting during exercise, which should require detailed explanation and investigation.

Sudden cardiac death occurs in approximately one per 200,000 young athletes per year, usually triggered during competition or practice. The victim is usually male and associated with soccer, basketball, ice hockey, or American football, reflecting the large number of athletes participating in these sustained and strenuous sports. For a normally healthy age group, the risk appears to be particularly magnified in competitive basketball, with sudden cardiac death rates as high as one per 3,000 annually for male basketball players in NCAA Division I. This is still far below the rate for the general population, estimated as one per 1,300–1,600 and dominated by the elderly. However, a population as large as the United States will experience the sudden cardiac death of a competitive athlete at the average rate of one every three days, often with significant media coverage heightening public attention.

The sudden deaths of 387 young American athletes (under age 35) were analyzed in a 2003 medical review:
