Abstract
Troponin concentrations were measured at the start of exercise and then hourly for up to 6 hours during each study visit, followed by measurements at 1, 2, and 7 days thereafter using the ARCHITECT SB STAT sb high-sensitive troponin I assay (Abbott Laboratories). Troponin concentrations were significantly higher after the shorter duration of high-intensity exercise (peak, 13.0 ng/L [6.5-27.1]) compared with the longer duration of moderate-intensity exercise (6.9 ng/L [2.9-7.9]; 2-way ANOVA, I P i =0.028). Differences in the cellular mechanisms of release are likely to explain why the duration of exercise-induced troponin release is significantly shorter than in acute myocardial infarction, where troponin concentrations remain elevated for >1 week.
