Bivalirudin Angioplasty Trial  A trial comparing bivalirudin/Angiomax to heparin in patients undergoing percutaneous transluminal coronary angioplasty (PTCA) for unstable angina.
 
Primary endpoint

Conclusion
Post-PTCA for unstable angina, ASA and bivalirudin/Angiomax has fewer cardiac and haemorrhagic in-hospital events than ASA and heparin; post-PCI infusion of antithrombotics was used in both study groups.

Logistics
