BACKGROUND: Cardiac contusion, asociated with on blunt chest trauma, was investigated according to changes of CPK, CKMB, ECG and especially cTnl levels.
METHODS: In this study, 88 cases with blunt traumas were evaluated prospectively. 61 cases with thoracic trauma and 27 cases without thoracic trauma as the control group were studied.
RESULTS: In 12 of61 cases with thoracic trauma cTnl was elevated. cTnl showed no increase in cases without thoracic trauma. CKMB level was high in both thoracic trauma and control groups. 11 of12 cases with elevated cTnl were traffic accidents. cTnl did not increase in 6 cases with sternum fractures.
CONCLUSIONS: We consider that decceleration wounds are the main cause of cardiac contusions. Altough thoracic trauma is essential in the pathogenesis of cardiac cortision, rib fracture is not a rule. Cardiac contusion is not related directly with degrees of body and thoracic trauma. However it is more related with the degree of cardiac trauma.
