Design Details

  • Primary Purpose: TREATMENT
  • Allocation: RANDOMIZED
  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Heparin
Heparin will be administered at a dose of 70 to 100 units per kilogram in patients not receiving glycoprotein IIb/IIIa inhibitors and at a dose of 50 to 70 units per kilogram in patients receiving glycoprotein IIb/IIIa inhibitors. Subsequent adjustment of the heparin dose on the basis of the activated clotting time will be left to the discretion of the treating physicians.
EXPERIMENTAL: Bivalirudin
Bivalirudin will be given as a bolus of 0.75 mg/kg followed by infusion of 1.75 mg/kg/h during the PCI procedure and for at least 30 minutes but no more than 4 hours afterwards. Following this mandatory infusion,a reduced-dose infusion (0.2 mg/kg/h) for up to 20 hours could be administered at physician discretion. An additional bivalirudin bolus of 0.3 mg/kg was given if the activated clotting time 5 minutes after the initial bolus was less than 225 seconds.
