Patient has hypertension, which in the opinion of the investigator, is uncontrollable with medication 10. Any contraindication (except intracerebral haemorrhage) to treatment with apixaban, dabigatran, edoxaban, rivaroxaban as per Summary of Product Charasteristics (SmPC) 11. Absolute need for antiplatelet therapy at enrolment 12. Presence of a left atrial appendage occlusion device (LAAO) or plan to implant an LAAO 13.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary end point(s): There are two co-primary binary endpoints in the Study (evaluated by time-to-event analysis): IS and recurrent ICH. The Study will perform hierarchical testing of the two co-primary endpoints in a parallel group design;Main Objective: The main objective is to perform a RCT to resolve the long-standing management dilemma of antithrombotic stroke prevention in intracerebral haemorrhage (ICH) survivors with comorbid atrial fibrillation (AF). Specifically, it will address the question whether direct oral anticoagulants (DOACs, intervention) provide a more effective option for prevention of ischaemic stroke (IS) and an equally safe option in terms of recurrence of ICH for antithrombotic stroke prevention in survivors of recent ICH compared to no anticoagulation (i.e. no antithrombotic therapy (noAT) or antiplatelet therapy (APA) at Principal Investigator´s discretion).; Secondary Objective: 1. To examine the effect of anticoagulation with DOAC versus no anticoagulation on major cardiovascular outcomes and mortality in ICH patient with AF 2. To compare the effect of DOACs versus no anticoagulation on major systemic and intracranial bleeding in this Study population (safety) 3. To examine the net clinical benefit of DOACs vs no anticoagulation in ICH patients with AF 4. To explore the impact of antithrombotic therapy on quality of life, development of cognitive deficits and psychological morbidity in patients with ICH and AF over time ;Timepoint(s) of evaluation of this end point: Anytime during follow-up period the end points will be evaluated and adjudicated | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary efficacy endpoints are 1. all stroke and systemic embolism 2. all-cause mortality 3. cardiovascular mortality 4. major adverse cardiac events 5. net clinical benefit defined as composite endpoint of all stroke, systemic embolic event, myocardial infarction, cardiovascular mortality, and major bleeding [14]. Secondary safety endpoints comprise of 1. any major haemorrhage according to International Society of Thrombosis and Hemostasis (ISTH) bleeding assessment tool 2. any intracranial haemorrhage ;Timepoint(s) of evaluation of this end point: Anytime during follow-up period the end points will be evaluated and adjudicated | — |
