BACKGROUND: The factors influencing three major outcomes-death, stroke/systemic
embolism (SE), and major bleeding-have not been investigated in a large
international cohort of unselected patients with newly diagnosed atrial
fibrillation (AF).
METHODS AND RESULTS: In 28,628 patients prospectively enrolled in the GARFIELD-AF
registry with 2-year follow-up, we aimed at analysing: (1) the variables
influencing outcomes; (2) the extent of implementation of guideline-recommended
therapies in comorbidities that strongly affect outcomes. Median (IQR) age was
71.0 (63.0 to 78.0) years, 44.4% of patients were female, median (IQR)
CHA2DS2-VASc score was 3.0 (2.0 to 4.0); 63.3% of patients were on anticoagulants
(ACs) with or without antiplatelet (AP) therapy, 24.5% AP monotherapy, and 12.2%
no antithrombotic therapy. At 2 years, rates (95% CI) of death, stroke/SE, and
major bleeding were 3.84 (3.68; 4.02), 1.27 (1.18; 1.38), and 0.71 (0.64; 0.79)
per 100 person-years. Age, history of stroke/SE, vascular disease (VascD), and
chronic kidney disease (CKD) were associated with the risks of all three
outcomes. Congestive heart failure (CHF) was associated with the risks of death
and stroke/SE. Smoking, non-paroxysmal forms of AF, and history of bleeding were
associated with the risk of death, female sex and heavy drinking with the risk of
stroke/SE. Asian race was associated with lower risks of death and major bleeding
versus other races. AC treatment was associated with 30% and 28% lower risks of
death and stroke/SE, respectively, compared with no AC treatment. Rates of
prescription of guideline-recommended drugs were suboptimal in patients with CHF,
VascD, or CKD.
CONCLUSIONS: Our data show that several variables are associated with the risk of
one or more outcomes, in terms of death, stroke/SE, and major bleeding.
Comprehensive management of AF should encompass, besides anticoagulation,
improved implementation of guideline-recommended therapies for comorbidities
strongly associated with outcomes, namely CHF, VascD, and CKD.
