Anticoagulation is the study and practice of preventing blood clots from forming in the body. This is typically done through the use of medications, such as anticoagulants, that inhibit the clotting process. Anticoagulation therapy is commonly used to treat and prevent conditions such as deep vein thrombosis, pulmonary embolism, and atrial fibrillation. It is important in preventing complications such as strokes, heart attacks, and other dangerous clot-related events. Monitoring and managing anticoagulation therapy is a key aspect of patient care in many clinical settings.
