Abstract 16828: Prognostic Value of Location of Occurrence in Sudden Cardiac Arrest During Sports
Background: No data aimed to evaluate characteristics and outcomes of sudden cardiac arrest (SCA) according to the location of occurrence (sports facilities vs. in the field). However, these information may be of particular interest to evaluate and improve cost-effectiveness of public access to defibrillation programs in the setting of sports practice.
Hypothesis: Location of occurrence of SCA during sport may be an important prognosis factor
Methods and Results: From a prospective comprehensive French registry of 820 SCA during sports among 10-75 year old population (2005-2010), 426 SCA (52%) occured in sport facilities whereas 394 occured in the field (48%). Patients presenting SCA in a sport facility were younger (42.1 vs. 51.3 years, P<0.0001), and had less frequently known cardiovascular diseases (5.2% vs. 18.5%, P<0.0001). The events were more often witnessed (99.8% vs. 84.9%, P<0.001), and 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 (collapse-to-Emergency Medical Services arrival 9.3 vs. 13.2 minutes, P=0.02), with a higher proportion of shockable rhythm (58.8% vs. 33.1%, P<0.0001). Finally, a higher survival rate at hospital discharge was observed among SCA in sports facilities (22.8%, 95% CI 18.8-26.8) compared to those occuring in the field (8.0%, 95% CI 5.3-10.7) (P<0.0001). After adjusting for potential confounding factors, location of occurrence was not associated with survival (OR 1.48, 95%CI 0.88-2.49, P=0.134).
Conclusions: Important disparities in subjects’ characteristics and circumstances are observed according to the location occurrence in case of SCA during sports activity. Those are associated with a 3-fold differences in survival rates.
