A 21year-old male presented to the emergency department with 6 h of atypical chest pain after suffering blunt chest trauma. His electrocardiogram revealed 1-1.5mm ST segment elevation in leads V1-V3 with reciprocal depressions in II, III, and aVF. Mid-anterior wall akinesis was observed on echocardiography associated with an estimated left ventricular ejection fraction of 40%. A left main coronary artery dissection was diagnosed and treated surgically with a bypass graft. Although rare, coronary dissections can be a catastrophic complication of chest trauma.
一名21岁男性在遭受钝性胸部创伤后出现6小时非典型胸痛，被送往急诊科。他的心电图显示V1-V3导联ST段抬高1-1.5毫米，II、III和aVF导联有对应性压低。超声心动图显示前壁中段运动减弱，估计左心室射血分数为40%。诊断为左主干冠状动脉夹层，并通过旁路移植术进行手术治疗。冠状动脉夹层虽然罕见，但可能是胸部创伤的灾难性并发症。
