Acute myocardial infarction caused by thrombosis of left main coronary artery generate acute cardiac failure, cardiogenic shock and death. Along with the clinical history, the electrocardiogram (EKG) is the most useful tool for its recognition and timely management. Classically the EKG shows ST elevation > 1 mm in aVR or V1 with ST depression in the other leads. Urgent coronary angiography with percutaneous coronary angioplasty using drug eluting stents is recommended when the diagnosis is made. We report two cases to exemplify the clinical presentation, EKG and angiographic findings and therapeutic approach.
左主冠状动脉血栓形成导致的急性心肌梗死会引发急性心力衰竭、心源性休克和死亡。结合临床病史，心电图（EKG）是识别该病并及时进行处理的最有用工具。典型的心电图表现为aVR或V1导联ST段抬高>1mm，其他导联ST段压低。一旦确诊，建议紧急进行冠状动脉造影，并使用药物洗脱支架进行经皮冠状动脉腔内血管成形术。我们报告两例病例，以举例说明临床表现、心电图及血管造影结果和治疗方法。
