As primary and secondary method for the prevention of acute strokes in patients with atrial fibrillation, antithrombotic therapy with vitamin K antagonist (VKA) or non-vitamin K antagonist oral anticoagulants (NOACs) is recommended.

However, data, concerning current emergency treatment for this patient group under acute ischemic stroke or acute intracerebral hemorrhage, is missing so far.

The aim of the registry, therefore, is to describe the emergency treatment of acute ischemic strokes in patients with different anticoagulants and under different diagnostic and therapeutic aspects.

Furthermore, risks of early complications and factors that affect the outcome of stroke patients after three months should be identified.


RASUNOA-Prime is a prospective, Investigator-Initiated, multicenter cohort study, including two sub-studies:

1. patients with acute ischemic stroke

2. patients with acute intracerebral hemorrhage


Continuously, patients with atrial fibrillation and acute ischemic stroke (ischemic stroke n = 3000, intracerebral hemorrhage n = 1000) in 42 neurologic clinics with certified stroke units are included in the study. To ensure a balanced admission into all three treatment patterns, patients are included according an algorithm, that defines, that whenever a patient receiving a NOAC is included in the study, a patient with VKA or  without any anticoagulation can also be included.

Data analysis includes specific information (laboratory values, thrombolytic or hemostatic therapy, complications) taken from the routine data of the hospital, as well as neuroradiologic imaging, that is be analysed centrally. Furthermore, patients are asked about their state of health in a 3-month-Follow-Up.
