Who should take warfarin instead of aspirin?

The oral anticoagulant warfarin is the treatment of choice for stroke patients with atrial fibrillation or certain other heart conditions, such as prosthetic heart valves or cardiac thrombus after a heart attack.

For many other people, however, there is no clear stroke-prevention benefit for warfarin over aspirin, an antiplatelet medication, and in such cases, American Heart Association/American Stroke Association (AHA/ASA) guidelines recommend antiplatelet therapy rather than anticoagulants to reduce the risk of a recurrent stroke or transient ischemic attack (TIA).
