Collagen Plug Vascular Closure Devices and Reduced Risk of Bleeding with Bivalirudin Versus Heparin Plus Abciximab in Patients Undergoing Percutaneous Coronary Intervention for Non ST-Segment Elevation Myocardial Infarction

In ISAR-REACT-4 (abciximab and heparin vs. bivalirudin for non-ST-elevation myocardial infarction [NSTEMI]), bivalirudin reduced the risk of bleeding after percutaneous coronary intervention (PCI) compared with unfractionated heparin plus abciximab (UFH + abciximab). Vascular closure devices (VCDs) may also prevent bleeding complications, and thus attenuate the benefit of bivalirudin. This analysis examined whether there exists an interaction on...
