Key result
Multimodality imaging and biomarkers differentiate Takotsubo syndrome from acute coronary syndrome and myocarditis.
Why the study?
Diagnosis of Takotsubo syndrome remains challenging due to heterogeneous presentations, evolving pathophysiological concepts, and significant overlap with acute cardiac conditions such as myocardial infarction, myocarditis, and other cardiomyopathies.
This narrative review synthesizes contemporary diagnostic criteria, clinical mimics, multimodality imaging, and biomarker strategies to guide the accurate diagnosis and individualized management of Takotsubo syndrome.

Supports careful differentiation of Takotsubo syndrome from ACS and myocarditis in practice; leaves open prospective validation of integrated and AI-assisted criteria.
Takotsubo syndrome (TTS), also known as stress-induced cardiomyopathy, is a form of transient left ventricular systolic dysfunction that typically mimics acute coronary syndrome (ACS). Although increasingly recognized, its diagnosis remains challenging due to heterogeneous clinical presentations, evolving pathophysiological concepts, and significant overlap with other acute cardiac conditions. Contemporary criteria, including the InterTAK diagnostic framework, aim to refine case identification, yet distinctions from myocardial infarction, myocarditis, and other cardiomyopathies often remain blurred. Advances in multimodal imaging, biomarkers, and artificial intelligence hold promise for improving diagnostic precision. This review explores current diagnostic challenges in TTS, integrating clinical presentation, mechanistic understanding, and management implications. By bridging mimics, mechanisms, and management, we highlight the need for a nuanced, multidisciplinary approach that balances clinical vigilance with emerging diagnostic tools to optimize patients’ outcomes.

Mitsis et al. (2026) conducted a review in Takotsubo syndrome (stress-induced cardiomyopathy). Multimodality diagnostic imaging, biomarkers, and clinical scores (e.g., InterTAK) vs. Acute coronary syndrome, myocarditis, and MINOCA mimics was evaluated. Takotsubo syndrome diagnosis requires integrating clinical triggers, biomarkers, and multimodality imaging to differentiate transient ventricular dysfunction from acute coronary syndrome and myocarditis.
