Background:
Neurally mediated reflex syncope (NMRS) has been recently described as a possible trigger of Takotsubo syndrome (TTS). There are few data in the literature about this association.
Methods:
In the present meta-summary, 6 case reports describing patients who experienced TTS following an NMRS episode were included. Patient characteristics, triggers and type of syncope were collected.
Results:
A total of 7 patients with a median age of 63.4 years (interquartile range, IQR: 47.5-76) were evaluated; 71.4% were females, mainly in the menopausal state (80%). The TTS triggers were: vasovagal syncope in 6 patients (85.7%) and situational syncope in 1 patient (14.3%). 2 patients underwent a comprehensive clinical evaluation which showed a cardioinhibitory response.
Conclusions:
NMRS due to sudden orthostatism and emotional stress, mainly with a cardioinhibitory response, has been associated with the onset of TTS, in particular among female patients in a menopausal state.
