Quality of anticoagulant control and patient experience associated with long-term warfarin in Canadian patients with non-valvular atrial fibrillation: A multicentre, prospective study.

We showed excellent overall TTR in an observed Canadian cohort, with monitoring through a dedicated anticoagulant clinic being associated with a statistically and clinically significant improvement in TTR. The burden of warfarin therapy on patients' health related quality of life or daily work and activities was low.
