Key result
Takotsubo syndrome exhibits stronger functional connectivity between sympathetic and parasympathetic autonomic nodes versus acute MI.
Why the study?
It was hypothesised that TTS and primary MVA may exhibit peculiar functional organisation of the central autonomic nervous system network at rest, as well as specific psychological patterns, compared to AMI.
Do patients with takotsubo syndrome and primary microvascular angina exhibit peculiar functional organisation of the central autonomic nervous system network and specific psychological patterns compared to patients with acute MI?

Hypothesis-generating for autonomic network changes in Takotsubo; leaves open diagnostic relevance versus MI or microvascular angina.
Purpose: We hypothesised that takotsubo syndrome (TTS) and primary microvascular angina (MVA) may exhibit peculiar functional organisation of the central autonomic nervous system network (CAN) at rest, as well as specific psychological patterns, when compared to patients with acute MI (AMI).

Cattaneo et al. (2020) conducted an observational in Microvascular Angina and Takotsubo Syndrome (n=50). Microvascular angina and Takotsubo syndrome vs. Acute myocardial infarction was evaluated on Intrinsic connectivity strength among the central autonomic nervous system (CAN) nodes (F 6.25, p=0.005). Patients with Takotsubo syndrome exhibited stronger functional connectivity between sympathetic and parasympathetic central autonomic nervous system nodes (p=0.005).
