BivaliRudin in Acute Myocardial Infarction vs Glycoprotein IIb/IIIa and Heparin :a Randomised Controlled Trial.

• Status: Completed
• Trial end date: 2014-07-01
• Target enrollment: 0
• Participant gender: All

Summary

The study would enrolled a total of 2100 AMI patients undergoing PCI to one of three antithrombotic regimens: bivalirudin alone, or unfractionated heparin alone, or unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor.

All enrolled patients would be followed-up to 30 days, 6 months, and 1 year. The purpose of the study is to evaluate the efficacy and safety of bivalirudin in AMI patients with DES.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No
