Acute myocardial infarction after blunt chest injury

A 20-year-old male sustained an inferior myocardial infarction following blunt chest trauma, after a motor vehicle accident. Though coronary arteriograms 9 months later were normal, LV angiography revealed severe hypokinesia of the inferobasal and diaphragmatic segments. The literature is reviewed with respect to mechanisms of injury, autopsy and angiographic findings and clinical outcome in this condition.
