Main finding · Coronary atherosclerosisResult — go to the resultOdds ratio (adjusted) 1.55 95% CI 0.81–2.93Authors' 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)
