Abstract
One of the most common manifestations of cardiac injury because of trauma is myocardial contusion. Today, the blurred definition and wide range of nonspecific clinical presentations led to absence in consensus of diagnostic pathways and criteria. Currently, the marker of cardiac injury measured at clinical level is troponin and instrumental diagnostic tool is ECG. The patients with elevated troponin level after the chest trauma should be suspected to have myocardial contusion as cardiogenic shock or arrhythmia might take place as a complication. The release of DAMPs after the trauma has been observed as a part of inflammatory response to it. HMGB1 protein and histone levels were found to be elevated in patients with trauma and associated to recruit the inflammation. In this review the potential of these molecules to be used as diagnostic markers of myocardial contusion is discussed. Moreover, the obstacles for implementing DAMPS to clinical protocols and future research directions are included.
