Competitors in an ultramarathon performed under extreme conditions did not demonstrate evidence of subclinical myocardial injury, as determined using cardiac troponin T as a marker. This finding refutes previous data and is likely due to utilization of an improved assay for cardiac troponin T that minimizes cross reactivity with skeletal muscle troponin T.
