title: [Should the patient with myocardial bridge be advised not to performe extreme sport effort? Case of a patient with troponin I elevation after exercise].
abstract: Elevated levels of cardiac troponins are an established method of diagnosis of heart muscle necrosis. A case of a long distance  amateur-marathon runner, who showed significant elevation of plasma troponin I after extreme physical effort is reported.  The diagnostic examinations did not reveal atherosclerosis burden, but myocardial bridging of coronary artery. The authors  describe the significance of the pathology in the view of extreme sport effort performed by the described patient.
