Chest Injury : Myocardial Contusion
This refers to any bruising of or contusion to the myocardium (heart muscle). Myocardial contusions are the result of injuries involving a sudden blunt force to the chest (e.g. motor vehicle accidents).
Myocardial contusions may be associated with: pneumothorax, sternum fracture, rib fracture, pulmonary contusion, or hemothorax. The bruised heart is subject to irregular heartbeats (arrhythmias), which can be life threatening.
There are no symptoms specifically attributable to myocardial contusion. This condition will often coexist with pulmonary contusion and sternum fracture, both of which can cause chest pain and shortness of breath. Any motor vehicle accident that results in the patient's chest impacting with the steering wheel could result in a myocardial injury.
Evaluation will include an EKG, cardiac enzymes, and continuous cardiac monitoring. Chest x-rays will be performed to rule out the presence of any serious associated injuries.
Hospitalization is required of all patients suspected of having sustained a myocardial contusion. Treatment by a Cardiologist or Thoracic Surgeon is necessary.
