Brief Summary:
The present study has been designed to describe the health-related quality of life in patients with non valvular atrial fibrillation who have been prescribed a specific anticoagulant treatment for their non valvular atrial fibrilation at least 6 months prior to study initiation. It will be conducted in Departments of Internal Medicine from approximately 50 centers in Spain. It consists of an only visit that will coincide with one of those performed by the patients as part of routine follow-up of their disease. 500 patients seen in internal medicine are planned to be included in the study

Primary Outcome Measures :
  1. Health Related Quality of Life (QoL) (HRQoL) Scores in the Spanish Adaptation of the Sawicki Questionnaire [ Time Frame: The study consisted of a single visit between April 2017 and January 2018 ]
    Sawicki questionnaire includes 32 items grouped in 5 dimensions: 1) general treatment satisfaction, 2) self-efficacy, 3) strained social network, 4) daily hassles and 5) distress. Patients estimated the impact of each item on their self-perceived treatment-related QoL on a scale of 1 (total disagreement) to 6 (total agreement). Response options for each question were: 1=not at all, 2=very little, 3=a little, 4=somewhat, 5=a lot, 6=very much. High scores in general treatment satisfaction and self-efficacy dimensions indicate high perceived HRQoL. Low scores in the strained social network, daily hassles and distress dimensions indicate high perceived HRQoL. The summary score for each dimension was calculated by dividing the total score of the sum of the items that comprise each dimension into the number of items included in that dimension. For the general treatment satisfaction dimension, the scores of individual questions have to be inverted first to calculate the dimension score.
