Coronary artery dissection after blunt trauma without abnormal electrocardiogram findings.

Coronary artery dissection after blunt trauma has rarely been reported, and all cases reported thus far have shown abnormal electrocardiogram (ECG) findings. We report a case of left main coronary artery dissection in the absence of abnormal ECG findings. This case suggests that coronary artery dissections should be considered in post-blunt trauma cases, even if patients present no laterality of blood pressure or present with normal findings on ECG and chest radiographs. In addition, physicians should follow up these patients closely before surgery.
