NCT01738100

Brief Summary

A 2 by 2 factorial, multicenter, prospective, randomized, open-label, blinded endpoint trial. Patients undergoing primary PCI for STEMI will be eligible. Enrolled patients will be randomly assigned to the ticagrelor group or the clopidogrel group in a 1:1 ratio. After emergent coronary angiography, patients who have thrombolysis in myocardial infarction (TIMI) flow grade \<2 in coronary angiogram will be randomized again, to either bolus intracoronary injection of morphine sulfate or saline in a 1:1 ratio. Randomization will be stratified by infarct location (anterior vs. non-anterior), and morphine use for pain control before study enroll (for only intracoronary morphine).

Outcome Measures

Primary Outcomes (1)

  • Myocardial infarct size measured by magnetic resonance imaging (MRI) at 3-5 days after the index procedure

    Post-PCI 3-5 days

Secondary Outcomes (7)

    30 min after completion of PCI

  • Enzymatic Infarct size by creatine kinase-MB (area under curve)

    1 month later

  • Myocardial salvage index measured by MRI

    Post-PCI 3-5 days

  • Major adverse cardiac events (a composite of death, myocardial infarction, severe heart failure, or stent thrombosis)

    1Month later

  • The extent of microvascular obstruction measured by MRI

    post-PCI 3-5days

  • +2 more secondary outcomes
