Abstract
In the past, myocardial contusions after blunt thoracic trauma [in humans] were frequently overlooked or missed unless hemodynamic instability or dramatic ECG findings were observed. This entity is now known to be more common than once believed. However, understanding of cardiac contusions remains unclear and obscure because of the inability to diagnose the condition accurately. Chest roentgenograms ECG and radionuclide imaging have less than optimal success. Apparently, the serial determination of creatine phosphokinase-myocardial band isoenzymes and subsequent 2-dimensional echocardiographic sector scanning are the most sensitive indicators of structural and functional cardiac injury presently available.
