Objective: We present the case of a 50-year-old patient, smoker, alcohol user, with untreated stable angina pec-toris who presented to the emergency department with severe chest pain which started about 4 hours earlier following a trauma by the fall of a solid object on his thorax. The anamnestic context requires the exclusion of a chest wall lesion, but at the same time it raises the problem of a heart lesion. Posttraumatic osteoarticular and pleuropulmonary lesions were not confirmed.

Methods: The ECG pattern of acute anterior wall ST-segment elevation myocardial infarction and signifi-cant increase of high sensitive troponin I (hs-TnI) drew our attention. Emergency echocardiography revealed anomalies of segmental left ventricular wall motion, moderate systolic dysfunction, and excluded other car-diac lesions.

Results: Primary percutaneous coronary intervention with drug-eluting stent is performed for thrombotic occlusion in the mid-segment of the left anterior des-cending coronary artery. The course was not compli-cated, but the left ventricular systolic dysfunction per-sisted.

Conclusions: T he presented case is particular due to the low prevalence of the posttraumatic acute myocardial infarction, mechanism of production, and diag-nostic and therapeutic management issues.
