It also has been increasingly recognized that some populations of athletes may be at substantially higher risk than others for SCD. 12 These inconsistencies help account for the wide range of estimated incidence of SCD in athletes in prior reports, from 1 in 3,000 up to 1 in 1 million. The definition of SCD in athletes also varies some estimates of incidence include only deaths with exertion or shortly (< 1 hour) after exertion, while others include any SCD in an athlete (exertional or outside of exertion) and also episodes of resuscitated sudden cardiac arrest (SCA). Therefore, when estimating SCD incidence, the population of athletes “at risk” may be difficult to quantify.

A competitive athlete has been proposed to be “one who participates in an organized team or individual sport that requires competition against others as a central component, places a high premium on excellence and achievement, and requires some form of systematic (and usually intense) training.” 13 This definition is considerably easier to apply to high school, collegiate, and professional organized sport participants but more difficult to apply to younger and older populations who participate in recreational activities (i.e., a heterogeneous group of adults participating in a running race). SCD in Athletes: Definitions and Epidemiology Therefore, considerable effort has been made to better understand the causes of SCD in athletes and to discover optimal strategies for prevention. 12 Though SCD is rare, its occurrence in athletes who are often young and presumably healthy has a large emotional and social impact on the surrounding community. A recent estimate of SCD incidence ranged from 1 in 40,000 to 1 in 80,000 athletes per year. Sudden cardiac death (SCD) is the most frequent medical cause of sudden death in athletes, and estimates vary widely based on the population. 10, 11 However, for a small number of individuals who harbor cardiac conditions, exercise can sometimes be associated with the risk of sudden death (i.e., the exercise paradox). 5–9 While there is controversy about the potential connection between intense endurance exercise and increased risk of some cardiac conditions (i.e., atrial fibrillation, ventricular fibrosis), on balance, exercise is clearly health-promoting for the large majority of individuals. 1–4 Numerous epidemiological studies have consistently shown an association between moderate aerobic exercise and decreased risk of coronary heart disease (CHD) and death, and even a small amount of exercise provides significant risk reduction compared to a sedentary lifestyle. Exercise is one of the most powerful tools for improving health and has been associated with beneficial change in most cardiovascular risk factors, including lipids, blood pressure, insulin sensitivity, and weight.
