This population-based, multicentre, 10-year study of the use of oral #anticoagulants for #stroke prophylaxis for ~0.5M patients with #AFib found that their prescription for patients with #AF at high risk of stroke increased by nearly 60%.
Between 2009 & 2018, 3352 individual General Practices provided a total of 5968 uploads into the GRASP-AF database. From the first upload per General Practice, there were an estimated 450 518 patients with #AFib from a total of 24 644 210 people.
Over the study period the prevalence of AF was 1.8% [95% CI 1.7–1.9%], which increased from 1.6% (1.5–1.7%) in 2009 to 2.4% (2.3–2.5%) in 2018 (P-trend < 0.001).
