Just as aspirin has become standard therapy in
reducing the risk of a second heart attack, it can be used under a
doctor's direction by thousands of stroke survivors to decrease the
likelihood of a second stroke.
Aspirin helps prevent the aggregation of platelets or blood
clotting. Platelets release a prostaglandin called thromboxane.
Asprin's irreversible prostaglandin blocking ability inhibits the
biosynthesis of thromboxane and, consequently, reduces the tendency
for blood to clot. This is the reason aspirin should not be used
with prescription drugs for anticoagulation (thinning the blood)
unless directed by a doctor.
An aspirin regimen may help prevent a second ischemic stroke, but
will not prevent hemorrhagic strokes. In fact, aspirin use slightly
increases the risk of hemorrhagic stroke. If you have a history of
stroke, make sure you know what kind of stroke you had.
Aspirin is not appropriate for
everyone, so be sure to talk to your doctor before you begin or
modify an aspirin regimen.
