In acute coronary syndrome, anticoagulation is used to prevent further thrombus formation by inhibiting clotting factors, providing rapid and controllable effects. The main choices are unfractionated heparin given intravenously for immediate action and easy reversal, or enoxaparin as a weight-based low-molecular-weight heparin with more predictable on‑field activity. In the cath lab, bivalirudin, a direct thrombin inhibitor, may be used as an alternative to heparin. Direct oral anticoagulants are not standard in the acute ACS setting because solid, actionable evidence supporting their routine use here is lacking and they complicate bleeding risk when combined with antiplatelet therapy. Warfarin monotherapy isn’t used acutely due to its slow onset and need for bridging, and aspirin alone is an antiplatelet agent, not an anticoagulant.
