Xarelto on Prevention of Stroke and Noncentral Nervous System Systemic Embolism in Treatment-naïve Asian Patients With Non-valvular Atrial Fibrillation

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to collect additional information of Xarelto treatment in routine clinical practice. Patients affected by atrial fibrillation and who will get Xarelto as a prophylactic treatment against stroke and systemic embolism (Stroke Prevention in Atrial Fibrillation) will be observed.

Detailed Description
-----------------
The study takes place in Korea and Taiwan. Approximately a total of 1200 patients will be included in the study within 12 months. The observation period for each patient is 1 year from enrollment into the study, or until withdrawal of consent or lost to follow-up. Patients will be followed according to routine medical practice and the frequency of visits and procedures will be performed under routine conditions.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Treatment-naïve NVAF patients in Korea and Taiwan<br>Patients will be followed according to routine medical practice and the frequency of visits and procedures will be performed under routine conditions. NVAF: Non-valvular atrial fibrillation | Drug: Rivaroxaban (Xarelto, BAY59-7939)<br>* Rivaroxaban is a direct Factor Xa inhibitor. In this non-interventional setting, the prescription and dosing scheme is up to the treatment physician, however, the recommended dosing scheme is 20mg/day (once daily) or 15 mg/day (once daily) in patients with reduced renal function<br>|
