In-hospital triggers of takotsubo syndrome: a case report on witnessing sudden death in a hospital roommate.

The case is classified as in-hospital TTS, occurring unexpectedly during medical care, and suggests that secondary TTS could represent a certain 'basic risk' for hospitalized patients. We want to emphasize the importance of reducing pain and fear in the hospital setting and encourage further research to understand the association between TTS and medical procedures and therapies. Overall, this case underscores the need for strategies to reduce the frequency of TTS in hospitalized patients.
