Abstract
Myocardial contusion is a rare and potentially fatal complication of chest trauma. There is no unique definition for this entity: some authors define myocardial contusion as a mild increase in cardiac biomarkers in the context of chest trauma, while for others the diagnosis requires evidence of pathologic findings at cardiac imaging. Consequently, the real incidence of myocardial contusion remains unknown, varying in reports between 8% and 71%. We describe a case of cardiac contusion secondary to a low-energy blunt chest trauma, manifesting as persistent ST-elevation associated with elevation of myocardial necrosis markers, with consequent myocardial stunning of the right ventricular free wall. As there is no consensus regarding the diagnostic pathway, it is essential to integrate first-level exams (ECG and laboratory findings) with cardiac magnetic resonance imaging, to define the presence of cardiac contusion and its extent, particularly if the echocardiographic data are unconclusive.
