exercise-induced cardiac biomarker surge
Acute elevation of multiple cardiac biomarkers following intense exercise, typically resolving within 24-72 hours in healthy athletes.
Full Definition
A phenomenon observed in athletes after prolonged or high-intensity exercise characterized by simultaneous elevation of various cardiac biomarkers including troponins, CK-MB, NT-proBNP, and others. This surge represents a physiological response to exercise stress rather than pathological cardiac damage. The pattern is distinguishable from pathological elevations by its rapid normalization, lack of associated symptoms, and absence of structural cardiac abnormalities on imaging. Sports cardiologists must recognize this normal response to avoid unnecessary diagnostic workups and inappropriate sport restrictions. The magnitude of surge often correlates with exercise intensity and duration.
Usage
Usage note: Always specify 'exercise-induced' to distinguish from pathological biomarker elevations.
