Why the study?
It was unclear whether maximal or prolonged high-intensity exercise affects post-exercise cTnI levels in well-trained individuals with stable revascularised CAD compared to those without obstructive CAD.
Does maximal or prolonged high-intensity exercise affect post-exercise cardiac troponin I levels differently in well-trained individuals with stable revascularised CAD compared to those without obstructive CAD?

Repeated cTnI sampling after maximal exercise should not yet change practice; leaves open its role in detecting evolving obstruction post-revascularization.
Does maximal or prolonged high-intensity exercise affect post-exercise cardiac troponin I levels differently in well-trained individuals with stable revascularised CAD compared to those without obstructive CAD?
Repeated post-exercise troponin I measurements, particularly after maximal exercise, may have diagnostic value for detecting evolving coronary artery obstruction in patients with revascularized CAD.
