Bivalirudin for percutaneous coronary intervention and in acute coronary syndromes.

This review focuses on the use of bivalirudin as a replacement anticoagulant for heparin in patients undergoing percutaneous coronary intervention, or who are being treated for unstable angina pectoris, ST-elevation, or non-ST-elevation myocardial infarction. Potential advantages of bivalirudin include a lack of dependence on antithrombin III for anticoagulant activity, the ability to inactivate both fibrin-bound and soluble thrombin, a lack of aggregatory effects on platelets, a predictable anticoagulant response without monitoring, and a wider therapeutic window. Clinical trial results to date suggest that bivlirudin is at least as effective as heparin with superior safety due to lower bleeding rates.
