Compliance of Atrial Fibrillation Treatment with the Atrial Fibrillation Better Care (ABC) Pathway Improves the Clinical Outcomes in the Middle East Population: A Report from the Gulf Survey of Atrial Fibrillation Events (SAFE) Registry

Abstract: Atrial fibrillation (AF) is associated with substantially increased risk of cardiovascular events and overall mortality. The Atrial fibrillation Better Care (A—Avoid stroke, B—Better symptom management, C—Cardiovascular and comorbidity risk management) pathway provides a simple and comprehensive approach for integrated AF therapy. This study’s goals were to evaluate the ABC pathway compliance and determine the main gaps in AF management in the Middle East population, and to assess the impact of ABC pathway adherence on the all-cause mortality and composite outcome in AF patients. 2021 patients (mean age 57; 52% male) from the Gulf SAFE registry were studied. We evaluated: A—appropriate implementation of OACs according to CHA2DS2-VASc score; B—symptom control according to European Heart Rhythm Association (EHRA) symptom scale; C—proper cardiovascular comorbidities management. The primary endpoints were the composite cardiovascular outcome (ischemic stroke or systemic embolism, all cause death and cardiovascular hospitalization) and all-cause mortality. One-hundred and sixty eight (8.3%) patients were optimally managed according to adherence with the ABC pathway. Over the one-year follow up (FU), there were 578 composite outcome events and 224 deaths. Patients managed with integrated care had significantly lower rates for the composite outcome and mortality comparing to non-ABC group (20.8% vs. 29.3%, p = 0.02 and 7.3% vs. 13.1%, p = 0.033, respectively). On multivariable analysis, ABC compliance was independently associated with reduced risk of composite outcome (HR 0.53; 95% CI 0.36–0.8, p = 0.002) and death (HR 0.46; 95% CI 0.25–0.86, p = 0.015). Integrated ABC pathway adherent care resulted in the reduced composite outcome and all-cause mortality in AF patients from Middle East, highlighting the necessity of promoting comprehensive holistic and integrated care management of AF.
