Abstract 13474: Sports-Related Sudden Death in the General Population
Background: Most epidemiologic studies on sports-related sudden death (SRSD) have focused on young competitive athletes. The prevalence and characteristics of SRSD have not previously been assessed, however, in a general population.
Methods: A prospective and comprehensive national survey was carried out throughout France from 2005 to 2009, involving over 100 million person-years of observation of subjects aged 10–75 years. Case detection for SRSD including resuscitated cardiac arrest was undertaken via national ambulance service reporting and web-based screening of media releases. Independent predictors of survival were assessed.
Results: Data were gathered from 752 cases of SRSD (age 46±15 years, 95 percent men), of whom 204 were initially resuscitated and survived to hospital admission (27.1 percent; 95 percent confidence interval, 24.7 to 29.5 percent). Only 53 subjects had previously known heart disease (8 percent). Fifty one percent of SRSDs occurred in a public sports facility, of which 99 percent were witnessed. Only 48 cases (6 percent) of SRSD occurred in young competitive athletes. Bystander cardiopulmonary resuscitation (OR: 1.96; 95 percent confidence interval, 1.01 to 3.89, P<0.05) and cardiac defibrillation (OR: 5.44; 95 percent confidence interval, 2.60 to 11.38, P<0.0001) were both independent predictors for survival to hospital discharge (approximately 13 percent).
Conclusion: Only a small proportion of SRSD occurs in young competitive athletes (<10 percent). SRSD in the general population mainly affects males aged 35–65 years with an incidence of approximately 17 to 18 cases per million population per year. Early bystander resuscitation and defibrillation are associated with improved survival.
