Chest pain after motor vehicle collision with an abnormal ECG - blunt cardiac injury? OMI? normal variant?

Discussion:Significant cardiac trauma occurs in approximately 10% of patients with severe blunt chest trauma. Isolated coronary artery dissection from blunt trauma is a very rare event. Traumatic dissections are most often seen in the LAD, followed by the RCA and LCX. It is thought that this is due to the relative anterior position of the LAD. The ECG is a report from the myocytes of their condition. They do not know the etiology of acute complete ischemia. No matter if its typical ACS, traumatic dissection causing acute occlusion, or spasm, it is the same result to the myocytes, and the same findings can be present on the ECG. References:Allemeersch, G.
