Bromocriptine-induced coronary spasm (BICS) causing myocardial infarction has been reported. Association between BICS and Takotsubo syndrome (TS) has not been described. We report on a 37-year-old woman presenting with a clinical picture of acute coronary syndrome 1 day after initiation of treatment with bromocriptine for ablactation 3 weeks after a full-term spontaneous vaginal delivery. Coronary angiography showed diffuse narrowing of a large diagonal branch. Left ventriculography showed widespread hypokinesia extending beyond the diagonal branch supply region. There was a slight elevation of myocardial infarction biomarkers that was disproportional to the degree of left ventricular dysfunction. Follow-up coronary angiography, intravascular ultrasound and left ventriculography showed normal coronary arteries including the diagonal branch and complete normalization of the left ventricular function. Cardiac magnetic resonance examination showed no signs of late myocardial gadolinium enhancement. The clinical picture and course of the disease was consistent with TS. Consequently, we describe for the first time a case of TS triggered by myocardial ischemia caused by BICS. Furthermore, our case and sufficient supporting data from the literature demonstrate that acute coronary syndrome is an important and frequent but up till now missed trigger factor for TS.
已有报道称溴隐亭诱发的冠状动脉痉挛(BICS)可导致心肌梗死。BICS与Takotsubo综合征(TS)之间的关联尚未见描述。我们报告了一名37岁女性,在足月自然阴道分娩3周后因回奶开始使用溴隐亭治疗1天后,出现急性冠状动脉综合征的临床表现。冠状动脉造影显示一大对角支弥漫性狭窄。左心室造影显示广泛的运动减退,范围超出对角支供血区域。心肌梗死生物标志物有轻微升高,与左心室功能障碍程度不成比例。随访冠状动脉造影、血管内超声和左心室造影显示包括对角支在内的冠状动脉正常,左心室功能完全恢复正常。心脏磁共振检查未显示晚期心肌钆增强迹象。临床表现和病程与TS一致。因此,我们首次描述了一例由BICS引起的心肌缺血触发的TS病例。此外,我们的病例以及文献中的充分支持数据表明,急性冠状动脉综合征是TS的一个重要且常见但至今被遗漏的触发因素。
