Bivalirudin in Acute Myocardial Infarction

November 25, 2016 updated by: Shenzhen Salubris Pharmaceuticals Co., Ltd.

Bivalirudin vs Heparin During Primary Percutaneous Coronary Intervention in Acute Myocardial Infarction: A Randomised Controlled Trial

The purpose of the study is to evaluate the efficacy and safety of bivalirudin in AMI patients with DES.

This is a prospective, randomized, single-blind, active drug controlled multicenter clinical research and the study would enrolled a total of 380 AMI patients undergoing percutaneous coronary intervention (PCI) to one of two antithrombotic regimens: bivalirudin alone, or unfractionated heparin alone. All enrolled patients would be followed-up to 30 days.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Bivalirudin
Bivalirudin will be started in the cath lab, 0.75 mg/kg intravenous bolus followed by 1.75 mg/kg per h infusion; if ACT<225s 5min after bolus, an additional dose of 0.3mg/kg bolus should be given. After procedure, a prolonged infusion (1.75mg/kg per h) will be given for at least 30 min (totally no more than 4 h) followed by a reduced dose infusion (0.2mg/kg per h) up to 20 h.
Drug: Bivalirudin
Patients would be given anticoagulant therapy with bivalirudin in acute myocardial infarction during emergency PCI operation.
Other Names:
  • Taijianing
Active Comparator: Heparin monotherapy
100 IU/kg intravenous bolus. If ACT <225s 5 min after bolus injection, additional dose of heparin (20U/kg) will be given.
Drug: heparin
heparin monotherapy
