High levels of troponin in athletes are not caused by narrowed coronary arteries, study finds

Exercising is healthy, but it also puts strain on the heart. During physical exertion, the protein troponin is released—a biomarker indicative of cardiac damage. New research from Radboudumc involving a thousand athletes shows that elevated troponin levels after exercise are not due to coronary atherosclerosis. This suggests that the cause of elevated troponin levels after exertion lies elsewhere.
