Takotsubo cardiomyopathy is associated with a constellation of cardiac findings including reversible left ventricular dysfunction and an acute triggering stressor. Epicardial coronary vasospasm is a rarely reported etiology for takotsubo cardiomyopathy, and its pathophysiologic mechanisms still remain incompletely understood. We present the case of a 54-year-old female with chest pain and ST-elevation myocardial infarction who was found to have takotsubo cardiomyopathy due to diffuse multivessel coronary artery vasospasm in the absence of obstructive coronary artery disease. To our knowledge, this is the first angiographically confirmed case of this rare phenomenon to be reported, as most literature involves focal, segmental, or single coronary artery involvement. Moreover, we review current literature and develop a discussion on the targeted treatment of vasospastic disease as part of the multimodal approach to the management of takotsubo syndrome.
应激性心肌病与一系列心脏表现相关,包括可逆性左心室功能障碍和急性触发应激源。心外膜冠状动脉痉挛是应激性心肌病一种罕见报道的病因,其病理生理机制仍未完全明确。我们报告一例54岁胸痛伴ST段抬高型心肌梗死的女性病例,该患者在无阻塞性冠状动脉疾病的情况下,因弥漫性多支冠状动脉痉挛而被诊断为应激性心肌病。据我们所知,这是首例经血管造影证实的该罕见现象的报道,因为大多数文献涉及局灶性、节段性或单支冠状动脉受累。此外,我们回顾了当前文献,并针对作为应激性心肌病多模式治疗一部分的血管痉挛性疾病的靶向治疗展开讨论。
