title: Survival from sports-related sudden cardiac arrest: In sports facilities versus outside of sports facilities.
abstract: BACKGROUND
  We sought to evaluate frequency, characteristics, and outcomes of sudden cardiac arrest (SCA) during sports activities according to the location of occurrence (in sports facilities vs those occurring outside of sports facilities).
  
  
  RESULTS
  This is an observational 5-year prospective national French survey of subjects 10 to 75 years old presenting with SCA during sports (2005-2010), in 60 French administrative regions (covering a population of 35 million people). Of the 820 SCA during sports, 426 SCAs (52%) occurred in sports facilities. Overall, a substantially higher survival rate at hospital discharge was observed among SCA in sports facilities (22.8%, 95% CI 18.8-26.8) compared to those occurring outside (8.0%, 95% CI 5.3-10.7) (P < .0001). Patients with SCA in sports facilities were younger (42.1 vs 51.3 years, P < .0001) and less frequently had known cardiovascular diseases (P < .0001). The events were more often witnessed (99.8% vs 84.9%, 0.0001), and bystander cardiopulmonary resuscitation was more frequently initiated (35.4% vs 25.9%, P = .003). Delays of intervention were significantly shorter when SCA occurred in sports facilities (9.3 vs 13.6, P=0.03), and the proportion of initially shockable rhythm was higher (58.8% vs 33.1%, P < .0001). Better survival in sports facilities was mainly explained by concomitant circumstances of occurrence (adjusted odds ratio 1.48, 95% CI 0.88-2.49, P = .134).
  
  
  CONCLUSIONS
  Sports-related SCA is not a homogeneous entity. The 3-fold higher survival rate reported among sports-related SCA is mainly due to cases that occur in sports facilities, whereas SCA during sports occurring outside of sports facilities has the usual very low rate of survival.
