The Atrial fibrillation Better Care (ABC) pathway was proposed for a more holistic or integrated care approach to atrial fibrillation (AF) management. We investigated whether adherence with the ABC pathway reduced the risk of adverse clinical outcomes in real-world AF patients starting vitamin K antagonist (VKAs) therapy.Prospective cohort study including AF outpatients starting VKA therapy from July 2016 to June 2018. Patients were considered as adherent if all ABC pathway criteria (A: Avoid stroke; B: Better symptom control; and C: Cardiovascular risk factors/comorbidities management) were fulfilled. The primary endpoints were all-cause mortality, net clinical outcomes (NCOs), major adverse cardiovascular events (MACE), and composite thrombotic/thromboembolic events at 2 years.We enrolled 1045 patients (51.6% female; median age 77 [70-83] years). Of these, 63.0% (658) were adherent to the ABC pathway and 37% (387) were considered non-adherent. Compared to non-adherent patients, those who were ABC adherent had lower event rates for all-cause mortality (13.76 vs. 6.56; p<0.001), NCOs (19.65 vs. 11.94; p<0.001), and MACE (11.88 vs. 7.75; p=0.006) during the follow-up. Adjusted Cox regression analyses demonstrated that the ABC pathway adherent care reduced the risks of all-cause mortality (aHR 0.57, 95% CI 0.42-0.78), NCOs (aHR 0.72, 95% CI 0.56-0.92), and cardiovascular mortality (aHR 0.54, 95% CI 0.32-0.90). Event-free survivals for all-cause mortality, NCOs (both log-rank p-values <0.001), and MACE (log-rank p-value = 0.004) were also higher in ABC pathway adherent patients.In this real-world prospective cohort of AF patients starting VKA therapy, adherence to the ABC pathway management at baseline significantly reduced the risk of NCOs, all-cause mortality, and cardiovascular death at 2 years.
