Coronary embolism is an uncommon cause of myocardial infarction. The usual source of a coronary embolus is an intracardiac thrombus or vegetation. Embolisation to the left main coronary artery is an extremely rare event and is usually fatal. We present a case of a 38-year-old woman with embolisation to the left main coronary artery which further embolised distally to the left anterior descending artery leading to a non-ST elevation myocardial infarction. The non-occlusive nature of the left main coronary artery embolus might have led to a favourable prognosis in our patient.
冠状动脉栓塞是心肌梗死的一种罕见病因。冠状动脉栓子的常见来源是心内血栓或赘生物。栓塞至左冠状动脉主干是极其罕见的事件，通常是致命的。我们报告一例38岁女性，其左冠状动脉主干发生栓塞，并进一步向远端栓塞至左前降支，导致非ST段抬高型心肌梗死。左冠状动脉主干栓子的非闭塞性可能导致了我们这位患者的良好预后。
