A case of acute myocardial infarction (AMI) due to thrombus in the left coronary cusp to the ascending aorta is described. There was no clinical evidence of coagulopathy, immunodisability, or local erosive lesion of the aortic and sinus of Valsalva wall macroscopically. Secondary polycythemia, induced by heavy smoking, was the likely cause of the myocardial infarction. Although this may be a rare case, intraaortic thrombus should be considered in the differential diagnosis of the causes of AMI.
本文描述了一例因左冠状动脉瓣叶至升主动脉血栓形成导致的急性心肌梗死（AMI）病例。宏观上，没有凝血病、免疫功能障碍或主动脉及主动脉瓣窦壁局部糜烂性病变的临床证据。重度吸烟引起的继发性红细胞增多症可能是心肌梗死的原因。尽管这可能是一例罕见病例，但在AMI病因的鉴别诊断中应考虑主动脉内血栓形成。
