Coronary artery aneurysms (CAAs) are rare, and aneurysms of the left main coronary artery are extremely rare. Atherosclerosis is the main cause of CAAs. An 87-year-old man with atypical chest pain of 1 month's duration presented to a hospital. Physical examinations of the patient's cardiopulmonary system and vital signs were unremarkable. Electrocardiography showed a right bundle branch block and an atypical ST-segment elevation in the inferior leads. Coronary angiography demonstrated a huge aneurysm in the left main without any clots. Additionally, there were no remarkable findings in cardiac monitoring and spiral chest computed tomography scanning. Ultimately, after he received nitroglycerin, β-blockers, Ca channel blockers, Aspirin (ASA), and clopidogrel (Plavix), his pain was relieved.
冠状动脉瘤（CAAs）较为罕见，而左主干冠状动脉瘤极其罕见。动脉粥样硬化是CAAs的主要病因。一名87岁男性因持续1个月的非典型胸痛前往医院就诊。对患者心肺系统及生命体征的体格检查未见异常。心电图显示右束支传导阻滞及下壁导联非典型ST段抬高。冠状动脉造影显示左主干有一个巨大动脉瘤，无任何血栓形成。此外，心脏监测及胸部螺旋计算机断层扫描均未发现明显异常。最终，在他接受硝酸甘油、β受体阻滞剂、钙通道阻滞剂、阿司匹林（ASA）和氯吡格雷（波立维）治疗后，疼痛缓解。
