Post-marathon marker elevations may be benign in asymptomatic runners; leaves open whether modern assays change risk interpretation or management.
Does marathon running elevate serum cardiac markers in asymptomatic runners?
Elevated serum cardiac markers, including troponins by first-generation assays, can occur in asymptomatic trained runners after a marathon without indicating acute cardiac injury.
Siegel et al. (2008) studied this question.
