Key result
Influenza A infection triggers delayed Takotsubo cardiomyopathy in a case report.
Why the study?
Only a few cases of influenza leading to Takotsubo cardiomyopathy have been reported, and the authors aimed to highlight this rare cardiac complication to raise clinical suspicion.

Does influenza A infection trigger Takotsubo cardiomyopathy?
This case highlights that influenza A infection can be a rare trigger for Takotsubo cardiomyopathy, warranting clinical suspicion in patients presenting with ACS symptoms post-infection.
Should prompt consideration of Takotsubo after influenza; single case leaves association hypothesis-generating.
We present a case of Takotsubo cardiomyopathy (TCM), commonly known as broken heart syndrome, triggered by influenza A infection. Known cardiac complications of influenza include myocardial infarction, myocarditis, and pericarditis. Only a few cases of influenza have so far been reported that led to TCM. We discuss the presentation, investigations, and management of a 67-year-old woman who presented to the emergency department (ED) with chest pain and shortness of breath two weeks after being diagnosed with influenza A. We aim to highlight a rare cardiac complication of influenza infection so that clinicians can have a high index of suspicion for this association.

Attique et al. (2026) conducted a case report in Takotsubo cardiomyopathy triggered by influenza A (n=1). Influenza A infection was evaluated on Development of Takotsubo cardiomyopathy. Influenza A infection triggered Takotsubo cardiomyopathy in a 67-year-old woman two weeks after her initial viral diagnosis.
