Antithrombotic therapy refers to the treatment or prevention of blood clots, which can lead to serious health issues such as heart attacks and strokes. This therapy involves the use of medications that either prevent the formation of blood clots or dissolve existing clots. Common antithrombotic agents include antiplatelet drugs like aspirin, anticoagulants like heparin and warfarin, and thrombolytic drugs like tissue plasminogen activator. Antithrombotic therapy is often used in patients with conditions such as atrial fibrillation, deep vein thrombosis, and coronary artery disease to reduce their risk of clotting-related complications.
