Key result
In phase III of the GLORIA-AF registry, 82.2% of patients with newly diagnosed atrial fibrillation were prescribed oral anticoagulation, with 59.5% receiving NOACs and 22.7% receiving VKAs.
Why the study?
The study was conducted to assess baseline characteristics and antithrombotic treatment prescription patterns in phase III of GLORIA-AF, evaluate predictors of prescription, and compare findings with phase II.

Data from phase III of the GLORIA-AF registry demonstrate that NOACs have become the standard treatment option for newly diagnosed atrial fibrillation globally, though regional undertreatment persists.
OBJECTIVE: To assess baseline characteristics and antithrombotic treatment (ATT) prescription patterns in patients enrolled in the third phase of the GLORIA-AF Registry Program, evaluate predictors of treatment prescription, and compare results with phase II. METHODS: GLORIA-AF is a large, global, prospective registry program, enrolling patients with newly diagnosed nonvalvular atrial fibrillation (AF) at risk of stroke. Patients receiving dabigatran were followed for two years in phase II, and all patients were followed for 3 years in phase III. Phase II started when dabigatran became available; phase III started when the characteristics of patients receiving dabigatran became roughly comparable with those receiving vitamin K antagonists (VKAs). RESULTS: Between 2014 and 2016, 21,241 patients were enrolled in phase III. In total, 82% of patients were prescribed oral anticoagulation ([OAC]; 59.5% novel/nonvitamin K oral anticoagulants [NOACs], 22.7% VKAs). A further 11% of patients were prescribed antiplatelets without OAC and 7% were prescribed no ATT. A high stroke risk was the main driver of OAC prescription. Factors associated with prescription of VKA over NOAC included type of site, region, physician specialty, and impaired kidney function. CONCLUSION: Over the past few years, data from phase III of GLORIA-AF show that OACs have become the standard treatment option, with most newly diagnosed AF patients prescribed a NOAC. However, in some regions a remarkable proportion of patients remain undertreated. In comparison with phase II, more patients received NOACs in phase III while the prescription of VKA decreased. VKAs were preferred over NOACs in patients with impaired kidney function.

Beier et al. (2022) conducted an observational in Newly diagnosed nonvalvular atrial fibrillation at risk of stroke (n=21,241). Antithrombotic therapy (NOACs, VKAs, antiplatelets) was evaluated on Prescription of oral anticoagulation (OAC). In phase III of the GLORIA-AF registry, 82.2% of patients with newly diagnosed atrial fibrillation were prescribed oral anticoagulation, with 59.5% receiving NOACs and 22.7% receiving VKAs.
