[Comment] Warfarin or novel oral anticoagulants for atrial fibrillation?

Stroke prevention is central to the management of atrial fibrillation and, until recently, the focus was to identify high-risk patients who would be given a so-called inconvenient drug, warfarin. Nowadays, the landscape for stroke prevention has changed with the availability of novel oral anticoagulants, and an increased appreciation that vitamin K antagonists (eg, warfarin) work best with high-quality anticoagulation control (shown by the average individual time in therapeutic range at an international normalised ratio of 2·0–3·0).
