Left coronary artery aneurysm and anteroseptal acute myocardial infarction following blunt chest trauma.

After a suicide attempt (fall from the ninth floor) a 28-year-old man presented with a blunt chest trauma. Electrocardiographic and enzymatic changes were characteristic of an acute anteroseptal myocardial infarction. A thallium myocardial scan showed decreased uptake of thallium over the septal area. Coronary angiography performed 6 weeks after the injury demonstrated aneurysmal dilatation of the left anterior descending artery which was patent, intramyocardial haemorrhage in the septum, and septal akinesia. The other left and right coronary arteries were normal. The patient remained asymptomatic 8 months later under medical treatment.
