How It Works Back to top
Anticoagulants are often called "blood thinners," although they don't really thin blood. They decrease the blood's ability to clot.
Why It Is Used Back to top
Anticoagulants are given in the hospital during unstable angina or a heart attack, because they can prevent clots from becoming larger and blocking coronary arteries. They are often given with other anticlotting medicines to help prevent or reduce heart muscle damage.
How Well It Works Back to top
Anticoagulants can help prevent another heart attack and lower the risk of dying soon after a heart attack. 1

Anticoagulants might be used after a person goes home from the hospital after a heart attack. These medicines can lower the risk of another heart attack, and they can lower the risk of stroke. For this long-term use, another type of anticoagulant, such as warfarin, is typically used.
When you take anticoagulants at home, you need to take extra steps to avoid bleeding problems. If you take warfarin, see:
