Takotsubo (stress-induced) cardiomyopathy in post-menopausal women

Traumatic Takotsubo Cardiomyopathy in a Patient with Extensive Coronary Artery Disease

Takotsubo Cardiomyopathy (TCM) should be considered in the differential diagnosis for patients with cardiovascular symptoms not only following emotional trauma but also following motor vehicle accidents. A 45-year-old woman presented with chest pain following a motor vehicle accident. While she had an elevated troponin level and an extensive history of cardiac disease, her electrocardiogram was normal. Echocardiogram, however, demonstrated transiently reduced left ventricular systolic function with mid to apical hypokinesis consistent with TCM. We emphasize the use of a diagnostic score and point of care focused cardiac ultrasound (FOCUS) to expedite the recognition, evaluation, and treatment of suspected TCM in an Emergency Department setting.

Takotsubo cardiomyopathy secondary to spontaneous right-sided pneumothorax

Takotsubo cardiomyopathy (TCM) is a unique type of cardiomyopathy characterised by left ventricular systolic dysfunction in association with stressful conditions. Patients with this condition usually present with chest pain and dyspnoea, and the presentation can mimic acute coronary syndrome. We present a case of a woman aged 58 years who presented with progressive dyspnoea and cough. Her initial evaluation was suggestive of acute myocardial infarction with elevated serum troponin T and ST segment elevation. Her chest radiograph showed a large right-sided pneumothorax, which was treated with chest tube insertion. Coronary angiography and echocardiogram did not show any evidence of obstructive coronary artery disease but did show a large area of akinesis consistent with TCM. The patient was managed medically with supportive care. Her pneumothorax resolved, and her follow-up echocardiogram also showed improvement. The association between pneumothorax and TCM is rare, and only four other cases have been reported so far in the English literature.
