Anticoagulant therapy is employed in a number of clinical situations, including:
- After an episode of thrombosis, such as deep venous thrombosis (DVT) in the veins of the legs, to prevent reoccurrence.
- Prophylactically after some surgeries, especially those involving vascular repair such as coronary bypass surgery to prevent clots from blocking newly formed vasculature.
- In heart valve and chamber disorders where there is an increased risk of thrombosis occurring.
