Myocardial bridging (MB) is a condition where the coronary artery is intramural instead of its natural course through the epicardium. Here, we present a case of a 25-year-old male without any medical history who presented with intermittent substernal chest discomfort on exertion. EKG was suggestive of ST changes in leads V1-V4 with right axis deviation. A left heart catheterization revealed myocardial bridging of the midportion of the left anterior descending artery. Myocardial bridging is commonly not associated with severe complications. However, it is imperative to diagnose it appropriately, especially in cases of chest pain, and provide immediate treatment to prevent mortality and morbidity.
心肌桥（MB）是一种冠状动脉走行于心肌内而非正常经心外膜走行的情况。在此，我们报告一例25岁男性病例，该患者无任何病史，因运动时出现间歇性胸骨后胸部不适前来就诊。心电图提示V1 - V4导联ST段改变伴电轴右偏。左心导管检查显示左前降支中段存在心肌桥。心肌桥通常不伴有严重并发症。然而，准确诊断它至关重要，尤其是在胸痛病例中，并且要立即进行治疗以预防死亡和发病。
