Background: Sudden death rates have been recorded for endurance sports such as long-distance running. Acute coronary syndromes (ACS) producing myocardial ischemia have been documented to account for approximate 16% of sudden death cases – with the majority of these cases being reversible by CPR/defibrillation/emergent angioplasty. Acute coronary syndromes – unstable angina and acute myocardial infarction – that do not produce sudden death may also occur during endurance sports, but the frequency at which these occur is less well-documented.
Objectives: The aim of the current study is to look at the experience of the heart catheterization laboratory at Mayo Clinic Rochester to determine the number and distribution of cases of ACS associated with The Med City Marathon held in Rochester, MN.
Methods: We examined the incidence of acute coronary syndromes and sport related events (SREs) in the longest endurance event with the highest level of participation – the Med City Marathon – from 1999 to 2015. Characteristics of ACS and SRE events were analyzed by reviewing Mayo Clinic medical records for a period of 1 month after the marathon.
Results: Of 13,162 competitors, 67% were men (mean age of all competitors = 40 ± 7 years). There were 65 SREs associated with the Med City Marathon, 12 of which (18%) presented as possible cardiac events: chest pain 8 (67%); syncope/presyncope 3 (25%), and palpitations 1 (8%). The remaining SREs were largely musculoskeletal (N=50). The total incidence of possible cardiac events in participants was thus 0.09% or slightly less than 1 per 1000 person-events. After initial work-up, only 2 cases (17%) were found to be potentially due to myocardial ischemia with mild troponin increase and ST changes. In both cases, symptoms and ECG changes resolved in the chest pain observation unit, and subsequent stress tests were normal.
Conclusions: Serious cardiac events, including ACS, during long distance races are rare. The majority of medical encounters are of minor severity. Of 13,162 race participants, there were only 2 suspected ACS events, neither of which led to PCI or other coronary intervention.
