Survival from Sports-Related Sudden Cardiac Arrest: In Sports Facilities versus Outside of Sports Facilities Running Title: Sports-Related Sudden Cardiac Arrest

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 versus those occurring outside of sports facilities). Methods and Results – Observational 5-year prospective national French survey of subjects 10-75 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 SCA (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<0.0001). Patients with SCA in a sports facility were younger (42.1 vs. 51.3 years, P<0.0001) and less frequently had known cardiovascular diseases (P<0.0001). The events were more often witnessed (99.8% vs. 84.9%, P<0.001) and bystander cardiopulmonary resuscitation more frequently initiated (35.4% vs. 25.9%, P=0.003). Delays of intervention were significantly shorter when SCA occured in sports facilities (9.3 vs. 13.2 minutes, P=0.02) and the proportion in initially shockable rhythm was higher (58.8% vs. 33.1%, P<0.0001). Better survival in sport facilities was mainly explained by concomitant circumstances of occurrence (adjusted OR 1.48, 95%CI 0.88– 2.49, P=0.134). Conclusions – Sports-related SCA is not a homogeneous entity. The three-fold higher survival rate reported among sports-related SCA is mainly due to cases which occur in sport facilities, whereas SCA during sport occurring outside of sports facilities suffers from the usual very low rate of survival.
