Before blaming the tooth extraction for the TTS, consider alternative triggers.

Takotsubo syndrome (TTS), also known as stress cardiomyopathy; is characterized by a clinical presentation similar to that of myocardial infarction but with normal coronary arteries. Four subtypes of TTS are distinguished, the classical type (apical form), the basal subtype, the reverse subtype, and the global subtype. TTS is triggered by physical stress in one-third of cases, by psychological stress in another third, and in the remaining third of cases the trigger remains unknown. Whether stress during tooth root extraction can trigger TTS is unknown but some rare reports suggest that such a dental procedure can trigger TTS. However, before tooth root extraction can be held responsible for triggering TTS, various different causes must be ruled out.
