  1. Comparison of ages, sexes, breeds and resting heparin plasma hscTnT concentrations from 303 apparently healthy horses (Non-Competition Horses and Racing-Thoroughbreds) as well as two clinical cases
  2. aHeparin plasma hscTnT sample taken 5 h after race-induced upper respiratory crisis event
  3. bHeparin plasma hscTnT sample taken 41 h after initially presented to clinic
  4. cIndicates a significant difference from Non-Competition Horses
