Challenges of Chronic Cardiac Problems in Survivors of Takotsubo Syndrome

A hallmark feature of the Takotsubo syndrome (TTS) is the reversible nature of the observed cardiac dysfunction. This is underlined in diagnostic criteria. However, it would appear this reversibility is a subtle process, and that myocardial catecholamine toxicity can cause lasting permanent abnormalities of myocardial physiology. A growing body of evidence suggests persisting abnormalities may predispose post-TTS patients to cardiac and noncardiac morbidity and mortality. The cardiology community needs to understand more clearly how TTS evolves, how to identify high-risk patients with incomplete resolution, and perform studies to assess which treatment(s) are effective to improve cardiac recovery and clinical outcomes
