A Case of Takotsubo Cardiomyopathy in a 65-Year-Old Woman Triggered by Emotional Stress

Takotsubo cardiomyopathy (TCM), also known as stress-induced cardiomyopathy or "broken heart syndrome," is a transient cardiac condition that often mimics acute coronary syndrome (ACS) but lacks obstructive coronary artery disease. TCM primarily affects postmenopausal women and is often precipitated by physical or emotional stress. This report presents a case of TCM in a 65-year-old woman, emphasizing the diagnostic challenges and clinical management required to distinguish TCM from ACS. A 65-year-old woman presented to the emergency department with sudden chest pain and dyspnea following a recent emotional stressor. Her initial evaluation, including an ECG showing ST-segment elevation and mildly elevated troponin, suggested ACS. However, coronary angiography revealed no significant stenosis, and echocardiography demonstrated apical ballooning with preserved basal segment function, confirming a diagnosis of TCM. She was treated supportively with beta-blockers and an ACE inhibitor. Her hospital course was stable, and follow-up echocardiography showed normalization of left ventricular function, consistent with full recovery. This case contributes to the understanding of TCM, emphasizing the need for awareness in clinical practice to promptly diagnose and manage TCM effectively. Enhanced recognition of its triggers, pathophysiology, and diagnostic criteria can improve patient outcomes and reduce the risk of recurrence.
