Background: Direct oral anticoagulants (DOACs) were developed as an alternative to vitamin K antagonists (VKAs) and are commonly used for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). Unlike VKAs, DOACs do not require Internal Normalized Ratio (INR) monitoring, but regular intake is as important for effective anticoagulation., Objectives: This study examined treatment persistence among patients receiving oral anticoagulants (OACs) for NVAF., Methods: Within the French healthcare claims database (SNDS), we assessed and compared the rates of non-persistence (≥ 30-day treatment gap) among patients with NVAF initiating an OAC between January 2014 and December 2016. The time-to-event of non-persistence was computed and plotted using a cumulative incidence function accounting for the competing risk of mortality. After adjusting on confounding factors, the risk for non-persistence was compared between apixaban and each other OACs using a Cox proportional hazard model, or Fine and Gray models., Results: In a cohort of 321,501 OAC-naive patients with NVAF, the cumulative incidence of non-persistence at 12 months considering competing risk was 44.3%, 31.0%, 41.3% and 46.8% for VKAs, apixaban, rivaroxaban and dabigatran, respectively. Median therapy duration before non-persistence ranged between 70 and 121 days. Non-persistence was lower with apixaban compared with VKAs (HR=0.63, 95%CI=[0.62-0.64]), rivaroxaban (HR=0.71, 95%CI=[0.70-0.73]), and dabigatran (HR=0.60, 95%CI=[0.59-0.62])., Conclusions: In this nationwide observational study, non-persistence rates of oral anticoagulant treatment were high in patients treated for NVAF. Apixaban-treated patients seem to experience lowest discontinuation rates 12 months after treatment initiation compared to patients treated with any other OAC., (Copyright © 2022 The Authors.

Background: There is a dearth of updated epidemiological data on the prevalence and annual incidence of coronary artery disease (CAD) and lower extremity artery disease (LEAD) in Western countries., Aims: To describe the incidence and prevalence of CAD and LEAD, associated medication patterns and long-term outcomes in France., Methods: This was a retrospective cohort study using French claims data from a representative sample of the French general population. Any hospitalization or long-term disease status for CAD or LEAD between January 2010 and December 2016 was collected to identify incident cases., Results: Of the 763,338patients screened in the study period, 8559 incident cases of CAD and 4399 of LEAD were identified, with an overall mean follow-up of 2.9±2.0years. The incidence of CAD, LEAD and CAD or LEAD remained stable over the years, and in 2016 were at 33.5 per 10,000person-years, 15.1per 10,000person-years and 42.5 per 10,000person-years, respectively. The prevalence of CAD increased from 3.1% in 2010 to 4.2% in 2016, and LEAD from 1.6% to 2.4%. Most patients received guideline-recommended medication with antithrombotic drugs and lipid-lowering drugs following the index event. However, most of the medications initiated were subsequently discontinued during follow-up. Incident CAD or LEAD was associated with considerable morbidity-particularly an incidence of all-cause hospitalization of 7976.9 per 10,000person-years-and all-cause mortality, with an incidence of 542.8 per 10,000person-years., Conclusion: In recent years, the prevalence of CAD or LEAD has increased progressively, resulting in considerable morbidity and mortality., (Copyright © 2019 Elsevier Masson SAS.
