Takotsubo cardiomyopathy (TCM) associated with left ventricular outflow tract (LVOT) obstruction in the event of an ST-elevation myocardial infarction (STEMI) is a rare cause of hypotension during percutaneous coronary intervention (PCI). Herein, we describe a 57-year-old woman who presented with STEMI and underwent PCI. She developed hypotension which worsened during inotropic therapy. Echocardiography revealed evidence of LVOT obstruction in the setting of TCM. Therefore, inotropic support was promptly discontinued. Beta blockers and phenylephrine were rapidly administrated, resulting in improved blood pressure and stabilisation of the patient.
应激性心肌病（TCM）并发 ST 段抬高型心肌梗死（STEMI）时导致左心室流出道（LVOT）阻塞，是经皮冠状动脉介入治疗（PCI）期间发生低血压的罕见原因。在此，我们描述了一位 57 岁女性，她因 STEMI 就诊并接受了 PCI。她出现低血压，在正性肌力治疗期间恶化。超声心动图显示 TCM 合并 LVOT 阻塞。因此，立即停止了正性肌力支持。快速给予β受体阻滞剂和去氧肾上腺素，血压改善，患者病情稳定。
