Here we present a case of a 70-year-old man with acute myocardial infarction caused by left anterior descending artery occlusion presenting as ST elevation in the inferior leads that suggested an occlusion of the right coronary artery. In contrast, coronary angiography results indicated a complete occlusion of the proximal left anterior descending coronary artery. We reported our observation in electrocardiographic data and coronary angiography and its changes after a percutaneous coronary intervention, and then we discuss its pathophysiologic mechanism.

在此，我们报告一例70岁男性患者，其因左前降支动脉闭塞导致急性心肌梗死，心电图表现为下壁导联ST段抬高，提示右冠状动脉闭塞。然而，冠状动脉造影结果显示左前降支冠状动脉近端完全闭塞。我们报告了心电图数据及冠状动脉造影结果以及经皮冠状动脉介入治疗后的变化，随后讨论其病理生理机制。
