Diagnosing and selecting an appropriate treatment strategy for left main coronary artery (LMCA) obstruction is very important. Although this disease is not frequently encountered, it can cause severe hemodynamic deterioration resulting in a less favorable prognosis without a suitable management approach. Another aspect of LMCA that we must not overlook is coronary artery spasm, which can be an infrequent but important cause of acute coronary syndrome. Although it is rare, LMCA can cause critical complications. In this study, we report the case of a 35-year-old female who was admitted to the hospital with a diagnosis of acute myocardial infarction with ST-segment elevation in the aVR lead caused by a left main coronary spasm that was examined on intravascular ultrasound.
诊断和选择合适的治疗策略对于左主干冠状动脉（LMCA）阻塞非常重要。虽然这种疾病并不常见，但如果没有适当的治疗方法，它可能导致严重的血流动力学恶化，从而导致预后较差。我们不能忽视 LMCA 的另一个方面是冠状动脉痉挛，它可能是急性冠状动脉综合征的一个不常见但重要的原因。虽然很少见，但 LMCA 可能会导致严重的并发症。在本研究中，我们报告了一例 35 岁女性患者的病例，该患者因左主干冠状动脉痉挛导致 aVR 导联 ST 段抬高型急性心肌梗死入院，该病例通过血管内超声检查得到确诊。
