Study Arms:
- Bivalirudin (Type: EXPERIMENTAL): 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.
- Heparin monotherapy (Type: ACTIVE_COMPARATOR): 100 IU/kg intravenous bolus. If ACT \<225s 5 min after bolus injection, additional dose of heparin (20U/kg) will be given.
- heparin plus tirofiban (Type: ACTIVE_COMPARATOR): heparin 60 IU/kg intravenous bolus and Tirofiban: 10μg/kg intravenous bolus followed by 0.15μg/kg per min infusion for up to 36h.

Based on this trial design, predict the completion outcome and termination type (if applicable).
