Two-year outcomes of patients with newly diagnosed atrial fibrillation: results from GARFIELD-AF
Authors' conclusion
The most frequent of the three major outcome measures was death, whose most common causes are not known to be significantly influenced by anticoagulation.
Study context
- Population
- Adults with newly diagnosed non-valvular AF (non-valvular atrial fibrillation (NVAF))
- Participants
- 17,162 adults
- Outcome
- All-cause mortality, stroke/systemic embolism and major bleeding
- Follow-up
- 2 years
Methodological detailsglobal, ongoing, Baseline: mean age 69.8 (SD 11.4) years; 43.8% women; mean CHA2DS2-VASc 3.3 (1.6), Therapy: 60.8% anticoagulant ± antiplatelet, 27.4% antiplatelet monotherapy, 11.8% no antithrombotic therapy
