© 2022 European Federation of Internal MedicineBackground: Effects of Atrial Fibrillation Better Care (ABC) adherence among high-risk atrial fibrillation (AF) subgroups remains unknown. We aimed to evaluate the impact of ABC adherence on clinical outcomes in these high-risk patients. Methods: EORP-AF General Long-Term Registry is a prospective, observational registry from 250 centres across 27 European countries. High-risk patients were defined as those with either CKD (eGFR <60 mL/min/1.73m2), elderly patients (≥75 years) or prior thromboembolism. Primary outcome was a composite event of all-cause death, thromboembolism and acute coronary syndrome. Results: 6646 patients with AF were screened (median age was 70 [IQR 61 – 77] years; 40.2% females). There were 3304 (54.2%) patients with either CKD (n = 1750), older age (n = 2236) or prior thromboembolism (n = 728). Among these, 924 (28.0%) were managed as adherent to ABC. At 2-year follow-up, 966 (14.5%) patients reported the primary outcome. The incidence of the primary outcome was significantly lower in high-risk patients managed as adherent to ABC pathway (IRR 0.53 [95%CI, 0.43 – 0.64]). Consistent results were obtained in the individual subgroups. Using multivariable Cox proportional hazards analysis, ABC adherence in the high-risk cohort was independently associated with a lower risk of the primary outcome (aHR 0.64 [95%CI, 0.51 – 0.80]), as well as in the CKD (aHR 0.51 [95%CI, 0.37 – 0.70]) and elderly subgroups (aHR 0.69 [95%CI, 0.53 – 0.90]). Overall, there was greater reduction in the risk of primary outcome as more ABC criteria were fulfilled, both in the overall high-risk patients (aHR 0.39 [95%CI, 0.25 – 0.61]), as well as in the individual subgroups. Conclusion: In a large, contemporary cohort of patients with AF, we demonstrate that adherence to the ABC pathway was associated with a significant benefit among high-risk patients with either CKD, advanced age (≥75 years old) or prior thromboembolism.
