The problem is that taking an anticoagulant AFTER THE FACT is not going to help much as taking nitro does during an angina attack, the latter being much faster acting and providing relief. An anticoagulant does not offer relief. It offers security against the risk of stroke during episodes of arrhythmia. If one is not sensitive to arrhythmias, but has them, of what use will be an anticoagulant that won't have much serum content and effect until approximately 40 minutes have passed since ingestion...about 40 minutes too late?

Eliquis and other anticoagulants are to be preventative. They're like a resume, an insurance policy, or a fire extinguisher; their use is immediate upon demand. Only if you actually take them, and only when they are present.
