Background:Guideline-adherent antithrombotic treatment (ATT) reduces the risk of stroke and death in patients with atrial fibrillation (AF). However, the effect of ATT adherence among different ethnicities remains uncertain. We compared the prognosis of AF patients in Japan and the UK according to guideline adherence status.Methods and Results:We compared the clinical characteristics and outcomes of AF patients from the Fushimi AF registry (Japan; n=4,239) and the Darlington AF registry (UK; n=2,259). ATT adherence was assessed against the Japanese Circulation Society Guidelines and UK National Institute for Health and Care Excellence guidelines. The rates of guideline-adherent ATT were 58.6% and 50.8% in the Fushimi and Darlington registries, respectively. There was no significant difference in 1-year stroke rates between Fushimi and Darlington (2.6% vs. 3.0%, P=0.342). On multivariate logistic regression analysis, non-guideline adherent-ATT was significantly associated with an increased risk of stroke (odds ratio [OR]: 1.69, 95% confidence interval [CI]: 1.21–2.34, P=0.002 for undertreatment, OR: 2.13, 95% CI: 1.19–3.80, P=0.010 for overtreatment). No significant interaction for ATT and the 2 populations was found in the incidence of stroke, all-cause death, and the composite outcome.Conclusions:Approximately half of the AF patients received optimal ATT according to guideline recommendations, which was associated with a lower risk of stroke. Furthermore, there was no interaction for the 2 populations and the influence of ATT adherence.
