PURPOSE: There is no reporting system for marathon-associated sudden cardiac arrest (SCA) or sudden cardiac death (SCD) in the United States. The purpose of this study was to estimate and characterize the risk of marathon related SCA to assist with emergency planning. METHODS: A retrospective, web-based survey was sent out to all US marathon medical directors (n=400) to gather details of SCA including demographics, resuscitation efforts, mortality, and autopsy results, if available. RESULTS: A total of 88 surveys (22%) were returned from marathons run from 1976-2009 for a total of 1,710,052 participants. Risks of SCA and SCD were 1 in 57,002 and 1 in 171,005, respectively. Men made up the vast majority of SCA victims (93%, mean age 49.7 years, range 19-82). Arrest site distributions were 0-5 miles (3), 6-14 miles (5), 15-22 miles (6), and 23-26.2 miles (16). Coronary artery disease was reported as the cause of death at autopsy in 7 of the 10 fatalities. An automated external defibrillator (AED) was used in 20/30 cases and associated with a higher survival (17/20 survivors versus 3/10 deaths; p = 0.0026). CONCLUSIONS: SCA occurs in approximately 1 in 57,000 marathon runners, is more common in older males, and usually occurs in the last four miles of the race course. Prompt resuscitation including early use of an AED improves survival. Emergency planning to include trained medical staff and sufficient AEDs throughout the race courseis recommended.
