Cardiac-related chest pain is a frequent cause of morbidity and mortality and should be carefully assessed due to its burden on patient health. Its etiology can sometimes prove challenging to discover because of atypical presentations or rare causes of chest pain like myocardial bridging (MB). MB requires a high index of suspicion to be diagnosed. MB is a rare congenital anomaly that occurs due to the passage of a segment of a coronary artery inside the myocardium, causing chest pain due to compression during systole. MB usually has no clinical significance in most cases. However, when severe bridging occurs in the major coronary arteries, patients can experience myocardial ischemia, coronary thrombosis, myocardial infarction, and stress cardiomyopathy, leading to arrhythmias and sudden death. We present the case of a young woman who presented with atypical (rather than ischemic) chest pain due to MB.
心脏相关胸痛是发病率和死亡率的常见原因，因其对患者健康造成负担，故应仔细评估。由于胸痛表现不典型或病因罕见，如心肌桥（MB），其病因有时难以发现。MB的诊断需要高度的怀疑指数。MB是一种罕见的先天性异常，由于冠状动脉的一段穿过心肌，在收缩期因受压而导致胸痛。在大多数情况下，MB通常无临床意义。然而，当主要冠状动脉发生严重桥接时，患者可能会出现心肌缺血、冠状动脉血栓形成、心肌梗死和应激性心肌病，导致心律失常和猝死。我们报告一例年轻女性因MB出现非典型（而非缺血性）胸痛的病例。
