Abstract
Background: Bivalirudin is a direct thrombin inhibitor with several pharmacological advantages over heparin. It has been studied extensively in non-ST elevation acute coronary syndromes (NSTE-ACS) and in percutaneous coronary intervention. Bivalirudin has also recently been investigated in patients with ST-elevation myocardial infarction (STEMI) treated with primary angioplasty and stenting. More than 27,000 patients were randomized in these trials. Objective: To provide an overview of the pharmacological properties of bivalirudin and its efficacy and safety profile in patients across the spectrum of acute coronary syndromes (ACS). Methods: All published, peer-reviewed clinical trials were reviewed and as relevant were included. Results and conclusions: Bivalirudin with provisional IIb/IIIa antagonists provides consistent results across the full spectrum of ACS, with similar or non-inferior protection from ischemic events and significantly reduces bleeding complications compared with heparin and IIb/IIIa antagonists. In STEMI, mortality at 30 days and 1 year is significantly reduced. The unique pharmacokinetic profile of bivalirudin allows for simultaneous reductions in both ischemic and hemorrhagic events and makes it an appropriate alternative to heparin.
