Authors' conclusion

The prevalence and magnitude of coronary atherosclerosis did not differ between recreational athletes with high vs low postexercise cTn concentrations.

Study context

Population
Middle-aged recreational long-distance walkers, cyclists and runners (median age 56 years, 63% male)68 high vs 34 low responders had computed tomography (CT)
Participants
1,011 walkers
Exposure
High vs low postexercise cardiac troponin (cTn) responders
  • High cTn respondersn = 68
  • Low respondersn = 34reference
Outcome
Prevalence and magnitude of coronary atherosclerosis on cardiac CT (CAD-RADS 2.0 score, CAC score)
