Should i take a daily aspirin to prevent stroke?

Depends: This should be discussed with your pcp. You may have risks that place your at high risk and need for asa or you may have other risks that would preclude your from being on aspirin. Not everyone is amenable to aspirin. Aspirin can have serious side effects. Your medications would dictate this too (or not). Be safe and discuss with your pcp/cardiologist/neurologit or other health care giver.

Answer: Aspirin is recommended for it's anti platelet properties, but before initiating a therapy on your own , talk to your primary physician, to rule out any contraindications or duplicate therapy, you might be on either Plavix or trental or Coumadin (warfarin) or fragmin, and he does not see the need to be on an additional drug.
