Takotsubo translates to "octopus pot" in Japanese. Takotsubo cardiomyopathy (TTC) is characterized by a transient regional systolic dysfunction of the left ventricle. Catecholamine excess is the one most studied and favored theories explaining the pathophysiology of TTC.
We present the case of a 52-year-old Hispanic female admitted for venlafaxine-induced TTC with a review literature on all the cases of Serotonin-norepinephrine reuptake inhibitors (SNRI)-associated TTC published so far.
SNRI inhibit the reuptake of catecholamines into the presynaptic neuron, resulting in a net gain in the concentration of epinephrine and serotonin in the neuronal synapses and causing iatrogenic catecholamine excess, ultimately leading to TTC.
“Takotsubo”在日语中意为“章鱼壶”。Takotsubo心肌病(TTC)的特征是左心室短暂性局部收缩功能障碍。儿茶酚胺过量是研究最多且最受认可的解释TTC病理生理学的理论之一。
我们报告了一例52岁西班牙裔女性因文拉法辛诱发TTC的病例,并回顾了迄今为止发表的所有与5-羟色胺-去甲肾上腺素再摄取抑制剂(SNRI)相关的TTC病例的文献。
SNRI抑制儿茶酚胺再摄取进入突触前神经元,导致神经元突触中肾上腺素和5-羟色胺浓度净增加,并引起医源性儿茶酚胺过量,最终导致TTC。
