alternatives to warfarin to prevent ischemic stroke in patients with atrial fibrillation (AF)

There has been lots of research into alternatives to warfarin to prevent ischemic stroke in patients with atrial fibrillation (AF)...but so far none have panned out.

The risk is highest in patients over age 75, or those with diabetes, hypertension, congestive heart failure, or a prior stroke or transient ischemic attack (TIA).
