A PHASE IV NON-INTERVENTIONAL STUDY. ADVERSE EVENTS (AES)/SUSPECTED ADVERSE DRUG REACTIONS (SADRS) ON THE PREVENTION OF STROKE AND SYSTEMIC EMBOLISM IN ADULT PATIENTS WITH NON-VALVULAR ATRIAL FIBRILLATION WITH ONE OR MORE RISK FACTORS AS PRIOR STOKE OR TRANSIENT ISCHAEMIC ATTACK; AGE >75; HYPERTENSION; DIABETES MELLITUS; SYMPTOMATIC HEART FAILURE (NYHA CLASS >II) AND PREVENTION OF VENOUS THROMBOEMBOLIC EVENTS (VTE) IN ADULT PATIENTS WHO HAVE UNDERGONE ELECTIVE HIP OR KNEE REPLACEMENT SURGERY UNDER TREATMENT WITH ELICUIS (REGISTERED) (APIXABAN)
