Ty of Dabigatran, Rivaroxaban, and Apixaban Versus Warfarin in Nonvalvular Atrial FibrillationXiaoxi Yao, PhD; Neena S. Abraham, MD, MSCE; Lindsey R. Sangaralingham, MPH; M. Fernanda Bellolio, MD, MS; Robert D. McBane, MD; Nilay D. Shah, PhD; Peter A. Noseworthy, MDBackground—The introduction of non itamin K antagonist oral anticoagulants has been a major advance for stroke prevention in atrial fibrillation; on the other hand, outcomes accomplished in clinical trials might not translate to routine practice. We aimed to evaluate the effectiveness and security of dabigatran, rivaroxaban, and apixaban by comparing each and every agent with warfarin. Techniques and Results—Using a big US insurance database, we identified privately insured and Medicare Advantage individuals with nonvalvular atrial fibrillation who were customers of apixaban, dabigatran, rivaroxaban, or warfarin in between October 1, 2010, and June 30, 2015.PDGF-AA Protein custom synthesis We developed three matched cohorts working with 1:1 propensity score matching: apixaban versus warfarin (n=15 390), dabigatran versus warfarin (n=28 614), and rivaroxaban versus warfarin (n=32 350).TINAGL1 Protein medchemexpress Employing Cox proportional hazards regression, we located that for stroke or systemic embolism, apixaban was related with lower danger (hazard ratio [HR] 0.PMID:24507727 67, 95 CI 0.46.98, P=0.04), but dabigatran and rivaroxaban had been linked having a similar threat (dabigatran: HR 0.98, 95 CI 0.76.26, P=0.98; rivaroxaban: HR 0.93, 95 CI 0.72.19, P=0.56). For significant bleeding, apixaban and dabigatran were connected with decrease risk (apixaban: HR 0.45, 95 CI 0.34.59, P0.001; dabigatran: HR 0.79, 95 CI 0.67.94, P0.01), and rivaroxaban was associated using a comparable threat (HR 1.04, 95 CI 0.90.20], P=0.60). All non itamin K antagonist oral anticoagulants have been related having a decrease danger of intracranial bleeding. Conclusions—In patients with nonvalvular atrial fibrillation, apixaban was related with decrease dangers of each stroke and major bleeding, dabigatran was related with equivalent risk of stroke but reduce risk of significant bleeding, and rivaroxaban was linked with similar risks of both stroke and significant bleeding in comparison to warfarin.
