Takotsubo cardiomyopathy (TTC) is frequently misdiagnosed as acute coronary syndrome in elderly patients. This case demonstrates how ECG findings facilitate a noninvasive diagnostic algorithm for TTC, validated by echocardiography and coronary computed tomography angiography (CCTA).
An 88-year-old woman presented with chest tightness and dyspnea after emotional stress (bereavement). Initial ECGs showed the concurrent appearance of ST-segment elevations in anterior (V3-V5) and inferior leads (II, III, aVF), suggesting apical injury and the diagnosis of TTC. Bedside echocardiography revealed apical akinesis with preserved basal contraction (LVEF 35%), while CCTA ruled out obstructive disease. Supportive therapy led to symptom resolution. At 1-year follow-up, LVEF recovered to 61% with normalized ECG.
This case highlights ECG's pivotal role in suspecting TTC, enabling a Noninvasive diagnostic approach (echocardiography + CCTA) for elderly patients.
在老年患者中，应激性心肌病（TTC）常被误诊为急性冠状动脉综合征。本病例展示了心电图表现如何助力TTC的无创诊断算法，并通过超声心动图和冠状动脉计算机断层扫描血管造影（CCTA）得到验证。
一名88岁女性在经历情绪应激（丧亲之痛）后出现胸闷和呼吸困难。最初的心电图显示前壁导联（V3-V5）和下壁导联（II、III、aVF）同时出现ST段抬高，提示心尖部损伤，诊断为TTC。床旁超声心动图显示心尖部运动减弱，基底段收缩功能保留（左心室射血分数35%），而CCTA排除了阻塞性疾病。支持性治疗使症状得到缓解。在1年随访时，左心室射血分数恢复至61%，心电图正常。
本病例突出了心电图在怀疑TTC时的关键作用，为老年患者提供了一种无创诊断方法（超声心动图 + CCTA）。
