We present a case of a 51-years-old woman with acute chest pain and ECG showing diffuse ST segment deviation who was transferred to our hospital to perform an urgent coronary angiography. There were no significant obstructions and left ventriculography (LVG) showed a midventricular ballooning without the apical dysynergy described previously in Tako-Tsubo or stress-induced cardiomyopathy. She had a favourable hospital course and a new LVG at 30 days showed total normalization of contractility. This recently described new pattern of transient left ventricular dysfunction was probably induced by a great mental stress state that the patient described in the preceding 24-48 h and the intrinsic mechanism could be a direct catecholamine myocardial damage or a microcirculation spasm.
我们报告一例51岁女性，因急性胸痛就诊，心电图显示广泛ST段偏移，被转至我院行紧急冠状动脉造影。造影显示无明显梗阻，左心室造影（LVG）显示心室中部气球样变，无此前在应激性心肌病或应激性心肌病中描述的心尖运动障碍。患者住院过程顺利，30天时再次行LVG显示收缩功能完全恢复正常。这种最近描述的短暂性左心室功能障碍新模式可能是由患者在之前24 - 48小时内描述的巨大精神压力状态诱发的，其内在机制可能是儿茶酚胺对心肌的直接损伤或微循环痉挛。
