Main objective
Scope: Efficacy
The objective of the study is to investigate whether treatment with: (i) adenosine and the adenosine reuptake inhibitor dipyridamole improves clinical outcomes in patients with Takotsubo Syndrome compared to standard of care (according to current recommendations from ESC taskforce for Takotsubo Syndrome (Randomization 1)
To test whether treatment with apixaban reduces the risk of thromboembolic events compared to no treatment with antithrombotic drugs (Randomization 2)

Study design 1 period
| # | Title | Allocation | Blinding | Roles blinded | Arms |
|---|---|---|---|---|---|
| 1 | BROKEN: Study period Multinational, multicentre, randomized, open, registry-based clinical trial (R-RCT), with 2x2 factorial design. The trial consists of 2 separate parallel studies and the patient is randomised to intervention or control group for both studies at the same time (if eligible) and the study procedures are independent of what randomised group the patient is belonging to. In the intervention arm, patients in randomization 1 will be treated with adenosine and dipyridamole, and patients in the control arm will receive treatment for TS according to recommendations from the ESC task force for TS. For randomization 2, the intervention arm patients will be treated with either apixaban or no anticoagulant whereas the control arm will either receive apixaban or no anticoagulant therapy. Patients may be randomized in only one of the two trials if they fulfil eligibility criteria for only one of the two trials. A follow-up will be performed at day 30 +7 by visit or phone call, depending on clinical routine.
