Periprocedural myonecrosis or infarction are associated with short, intermediate, and long term adverse outcomes. Previous study indicated 12.6% of patients suffered a peri-procedural CK-MB rise by overlapping use of drug-eluting stents for long coronary lesions. Here the investigators hypothesize that peri-procedural use of tirofiban could reduce the occurrence of periprocedural infarciton in elective patients with long coronary lesions treated by overlapping use of drug-eluting stents.

Condition Intervention Phase
Coronary Artery Disease Drug: tirofiban Drug: normal saline solution Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Efficacy of Peri-procedural Use of Tirofiban in Elective Percutaneous Coronary Intervention for Long Coronary Lesions With Overlapping Drug-Eluting Stent

Primary Outcome Measures:
  • periprocedural infarction [ Time Frame: 12h after procedure ]
    definition of periprocedural MI is a CK elevation >3 times the upper limit of normal.

Secondary Outcome Measures:
  • major bleeding [ Time Frame: during hospitalization (up to 2 weeks) ]
    The safety outcome of major bleeding according to the Thrombolysis in Myocardial Infarction (TIMI) definition

  • major adverse cardiac event [ Time Frame: one year after procedure ]
    major adverse cardiac event (MACE) includes cardiac death, target vessel revascularization, and re-occurrence of myocardial infarction after discharge

Enrollment: 748
Study Start Date: November 2011
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Control group
normal saline was applied to those randomized to control group, with same use as tirofiban
Drug: normal saline solution
same use as tirofiban
Experimental: Tirofiban group
after angioram, and before guiding catheter engagement: 10μg/kg bolus followed by 0.15μg/kg/min maintenance infusion

10μg/kg bolus followed by 0.15μg/kg/min maintenance infusion for 12h
Other Name: Xinweining, Grand Pharmaceutical Group, Wuhan, China

Detailed Description:
According to the results of 12.6% occurrence of peri-procedural myocardial infarction after long stent implantation by previous report[International Journal of Cardiology 2009;134: 231-237], the investigator hypothesize the 50% reduction of peri-procedural MI by using tirofiban. Three hundred and sixty-nine patients in each group are needed to reach 80% of power with α 0.05.
