Apixaban in patients with nonvalvular atrial fibrillation, heart failure and low body weight: A report from a global federated research dataset.

ABSTRACT:

Background

Atrial fibrillation (AF) and low body weight (BW, <60 kg) are common in patients with heart failure (HF). However, the safety and effectiveness of direct oral anticoagulants (DOACs) in this group remain unclear. This study compares the efficacy and safety of apixaban versus vitamin K antagonists (VKAs) in patients with nonvalvular AF, low BW and HF.

Methods

We analysed 155,152 patients with HF and AF, weighing ≤100 kg and treated with oral anticoagulants (apixaban 86,493; VKA 68,659), from the TriNetX Global Research Network. Outcomes included ischaemic stroke/systemic embolism (SEE), clinically relevant bleedings, intracranial haemorrhage (ICH), all-cause death and net clinical benefit (composite of stroke/SEE, bleedings and all-cause death) across three BW categ
