Heat stroke induced takotsubo cardiomyopathy with a transient Brugada-like electrocardiogram in a 79-year-old man, demonstrating that takotsubo cardiomyopathy can occur despite concurrent obstructive coronary artery disease.
Case Report (n=1)
Takotsubo cardiomyopathy can present with atypical Brugada-like ECG patterns during heat stroke and can be diagnosed even in the presence of severe obstructive coronary artery disease.
May support evaluating for takotsubo in heat stroke despite CAD; hypothesis-generating and requires prospective validation.
A 79-year-old man presented with impaired consciousness, fever with a body temperature of 41.1°C, and an electrocardiogram showing significant ST segment elevation in leads V1-6, coved-type ST elevation in leads V1-3, and partial right bundle branch block. Echocardiography revealed notable left ventricle dysfunction with apex-based akinesis. Coronary angiography confirmed severe obstructive lesions but left ventriculography displayed the distinct apical ballooning of takotsubo cardiomyopathy (TC). This case highlights the presence of atypical electrocardiographic patterns in TC influenced by comorbidities, supporting the diagnosis of TC despite concurrent obstructive coronary artery disease.

Sasaki et al. (2023) conducted a case report in Heat Stroke-Induced Takotsubo Cardiomyopathy (n=1). Heat stroke was evaluated. Heat stroke induced takotsubo cardiomyopathy with a transient Brugada-like electrocardiogram in a 79-year-old man, demonstrating that takotsubo cardiomyopathy can occur despite concurrent obstructive coronary artery disease.
