A 23-year-old man with no history of heart disease was admitted to Beijing Anzhen Hospital Affiliated to Capital Medical University for an abnormal electrocardiogram of ST-T changes mimicking myocardial infarction. Catheterization revealed normal coronary and peripheral arteries. The echocardiogram and delayed enhancement cardiovascular magnetic resonance imaging indicated a markedly reduced left ventricular function and enlarged left ventricular cavity with evidence of fibrous tissue. Given the patient's history of multiple blunt trauma 7 years previously and acute myocardial infarction diagnosis at that time, he was diagnosed with traumatic myocardial infarction (TMI). We describe the natural course of such a patient with TMI. There is a possibility of spontaneous healing of coronary artery dissection induced by trauma. Although early revascularization may be helpful for preventing cardiac remodeling after TMI in some cases, more data are needed to compare the long-term outcome among different interventions in large sample cases.
一位 23 岁的男性，无心脏病史，因心电图 ST-T 改变类似心肌梗死而入住首都医科大学附属北京安贞医院。导管检查显示冠状动脉和外周动脉正常。超声心动图和延迟增强心血管磁共振成像提示左心室功能明显降低，左心室腔扩大，有纤维组织证据。鉴于患者 7 年前曾多次钝性创伤史和当时的急性心肌梗死诊断，他被诊断为创伤性心肌梗死（TMI）。我们描述了此类 TMI 患者的自然病程。创伤引起的冠状动脉夹层有可能自发愈合。虽然早期血运重建可能有助于预防 TMI 后的心脏重构，但还需要更多数据来比较不同干预措施在大样本病例中的长期预后。
