Real-world clinical evidence on rivaroxaban, dabigatran, and apixaban compared with vitamin K antagonists in patients with nonvalvular atrial fibrillation: a systematic literature review
Abstract
Several comparative real-world effectiveness studies on direct oral anticoagulants (DOACs) have been conducted, but an overview of the available evidence remains to be developed, which could provide a better understanding of the value of DOACs relative to vitamin K antagonists (VKAs). A systematic literature review was conducted on the available real-world evidence (RWE) of three DOACs (rivaroxaban, dabigatran, and apixaban) compared with VKAs (e.g. warfarin), in patients with nonvalvular atrial fibrillation (NVAF).This systematic literature review included RWE published up to December 2016. Studies with > 50 patients reporting on incident and prevalent NVAF cases were included. The following databases were searched: Medline, Embase, and the Cochrane Library. Outcomes of interest included thromboembolic events, all-cause mortality, bleeding events, and nonpersistence. Of the 562 RWE DOACs articles retrieved, 49 presented results for rivaroxaban versus VKAs, 79 for dabigatran versus VKAs, and 18 for apixaban versus VKAs. Substantial heterogeneity was found across patient population, outcome definition, and follow-up period. Major bleeding, ischemic stroke, and intracranial hemorrhage were the most frequent outcomes analyzed. Ove...Continue Reading

Atrial Filbrillation
Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
Atrial Fibrillation
Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
Arrhythmia
Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
