Abstract

fetched live from OpenAlex

Vitamin K antagonists (VKAs, e.g. Warfarin) have been the cornerstone of stroke prevention in patients with non-valvular atrial fibrillation (AF) for well over 50 years, being highly efficacious in reducing stroke and mortality in this common arrhythmia. More recent data have shown the relative efficacy, safety, and convenience of the non-VKA oral anticoagulants (NOACs) over warfarin in patients with AF. Guidelines throughout Europe, America, and Canada acknowledge the value of NOACs and many recommend their use as first-line therapy, sometimes preferentially to warfarin. With the recent availability of reversal agents, there is little reason not to prescribe NOACs where appropriate. This article provides an overview of the current international guidelines with regard to NOAC use and highlights key areas by which emerging evidence may change the management of stroke prevention in patients with non-valvular AF.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
