Heart failure & cardiomyopathiesCohort study
Arterial hypertension in patients with takotsubo syndrome: prevalence, long-term outcome, and secondary preventive strategies: a report from the Takotsubo Italian Network register
- Registry-based cohort study
- multicentre
- consecutive patients
- propensity score weighting
Authors' conclusion
In this TTS study, HT did not affect the long-term risk of adverse events but increased the probability of benefit from BB treatment after discharge.
Study context
- Population
- Consecutive patients with takotsubo syndrome, Takotsubo Italian Network registerHypertension (HT) in 66%
- Participants
- 903 patients
- Exposure
- HT vs no HT; BB or renin-angiotensin-aldosterone system inhibitors (RAASi) at discharge vs none
- Outcome
- Composite of:
- All-cause death
- TTS recurrence
- Follow-up
- Longest available (median 2 years)
