Use of Aspirin for Primary Prevention of Heart Attack and Stroke. Reducing the possibility of having a first heart attack or stroke is called primary prevention. The FDA has reviewed the available data and does not believe the evidence supports the general use of aspirin for primary prevention of a heart attack or stroke.Is aspirin primary or secondary prevention?
In people who have had a heart attack or certain types of stroke, the use of aspirin to prevent a second event — potentially a fatal one — is firmly established. These uses of aspirin are called secondary prevention. Similarly, in people who have had stents or bypass surgery, lifelong daily aspirin is typically warranted.What is the risk of aspirin?
Gastrointestinal bleeding. Daily aspirin use increases your risk of developing a stomach ulcer. And, if you have a bleeding ulcer or bleeding anywhere else in your gastrointestinal tract, taking aspirin will cause it to bleed more, perhaps to a life-threatening extent.
