Dataset from FondaparinUx Trial With Unfractionated Heparin (UFH) During Revascularization in Acute Coronary Syndromes (ACS) (FUTURA). A Prospective Study Evaluating the Safety of Two Regimens of Adjunctive Intravenous UFH During PCI in High Risk Patients With Unstable Angina/Non ST Segment Elevation Myocardial Infarction (UA/NSTEMI) Initially Treated With Subcutaneous Fondaparinux and Referred for Early Coronary Angiography (OASIS 8)

The purpose of this study is to compare the safety of two different dose regimens of unfractionated heparin (UFH) during a percutaneous coronary intervention (PCI) procedure in patients with UA (unstable angina)/NSTEMI (non ST segment elevation myocardial infarction) who have been initially treated with fondaparinux.
