Clinical Implications • In patients with moderate-high risk ACS undergoing an early invasive strategy with use of GP IIb/IIIa inhibitors • Bivalirudin is an acceptable substitute for either unfractionated heparin or enoxaparin • However, compared to either UFH/enoxaparin with GP IIb/IIIa inhibition or bivalirudin with GP IIb/IIIa inhibition • A bivalirudin alone strategy results in significantly greater net clinical benefit and enhanced survival free from adverse events at 30 days
