Abstract

Cardiac troponins are a mainstay in the diagnostic approach of patients with suspected acute coronary syndrome. Along with other causes of cardiac injury, strenuous aerobic exercise is an important source of troponin leakage from myocardium. Due to recent immunoassays development, there is no information on variation of highly-sensitive (HS) troponin I (TnI) in ultra-marathon runners. We studied 15 healthy trained Caucasian athletes before and immediately after completion of a 60 km, ultramarathon. TnI was measured with both the conventional AccuTnI and the novel HS-AccuTnI immunoassays. At the end of the ultra-marathon the concentration of HS-AccuTnI significantly increased from the baseline value (19.2 ± 4.2 vs. 5.2 ± 0.8 ng/l; P = 0.001). The number of athletes displaying HS-AccuTnI values exceeding the 99th percentile of the reference limit was 2 (13%) pre-exercise, increasing significantly to 12 (80%; P
