Blunt chest trauma might lead to cardiac injury ranging from simple arrhythmias to lethal conditions such as cardiac rupture. We experienced a case of initially overlooked traumatic coronary artery dissection which resulted in acute myocardial infarction (AMI). A high degree of suspicion is needed to diagnose this condition. Based on our case, we will give an overview of relevant literature on this topic. ECG, echocardiography, coronary angiography and cardiac enzymes are valuable tools in diagnosing this rare condition. The time span from coronary artery occlusion to revascularisation must be short if AMI is to be avoided.

Blunt chest trauma might lead to cardiac injury ranging from simple arrhythmias to lethal conditions such as cardiac rupture. Acute myocardial infarction (AMI) may be induced by blunt chest trauma [1–3]. We experienced a case of coronary artery dissection with subsequent myocardial infarction from blunt chest trauma. We will give an overview of relevant literature regarding this topic.
Coronary artery injury may cause AMI, but the natural history of intimal rupture or dissection is not known. Spontaneous healing of the vessel has been described with some degree of residual stenosis  and without sequelae . Development of persistent angina pectoris following blunt trauma has been attributed to coronary artery injury in three cases [3, 11, 24]. Development of coronary artery aneurysm has also been reported .
AMI from blunt chest trauma has been managed in several ways. Conservative treatment with inotropic support, if necessary, has resulted in post-infarction sequelae with reduced ejection fraction and cardiac symptoms . Fibrinolytic therapy has been given after mild trauma . Acute percutaneous intervention (PCI) both without  and with stent implantation has been performed with successful revascularization and reversal of ST-elevations  although restenosis has been described . In our patient PCI was performed and a stent was implanted. As the condition was perceived as cardiac contusion and coronary artery injury was not suspected initially, cardiac catheterization and PCI was performed on the fourth day, after the AMI had taken place. Recovery was uneventful, however, and our patient was fully rehabilitated. Coronary artery bypass grafting has been performed acutely  and delayed in combination with coronary aneurysm repair  or resection of left ventricular aneurysm and coronary embolectomy . In the multi-traumatized patient off-pump coronary artery bypass (OPCAB) is probably favourable over on-pump surgery . OPCAB is performed without the use of cardiopulmonary bypass resulting in a less coagulopathic procedure. For patients with head injury cardiopulmonary bypass may be a particular risk as cerebral perfusion might be reduced. Avoiding cardiopulmonary bypass might also reduce the risk of organ failure. Moreover, avoiding cardioplegic arrest might be favourable in the case of cardiac contusion since myocardial ischemia also may contribute negatively.
The possibility of coronary artery injury should be kept in mind after blunt thoracic trauma. This condition probably is underdiagnosed being misinterpreted as cardiac contusion. Modern principles of coronary artery revascularization make myocardial salvage possible, also in the traumatized patient. Following a case of initially overlooked traumatic coronary artery dissection which resulted in AMI we have changed our diagnostic algorithm after blunt chest trauma. ECG is recorded from every patient together with cardiac enzymes. An abnormal ECG and/or abnormal cardiac enzymes warrant further investigation. Both echocardiography and coronary angiography are used when appropriate. The time span from coronary artery occlusion to revascularisation must be short if AMI is to be avoided.
The patient has given consent for the case report to be published.
The case report was presented at the 82nd annual meeting of The Norwegian Surgical Association in 2006. The conference proceedings have not been published in a peer reviewed journal.
