Outcome Measures

Primary Outcomes (1)

  • ratio of TMPG grade 2 and grade 3

    After PCI, TMPG grade will be evaluated and

    within 24 hours

Secondary Outcomes (9)

  • inhibition rate of platelet aggregation and GP1b receptor combination rate

    48 hours

  • Patients ratio of no-reflow to slow-flow in coronary artery after PCI therapy

    24 hours

  • Analysis of iconography reference: instant TIMI, CTFC and TMPG before/after the target vessel revascularization PCI therapy

    24 hours

  • The depression level of ST segment from right after the PCI therapy to 2 hours later

    within 24 hours

  • Compare the baseline troponin level to the troponin level at 24-26 hours after injection and at 3 days after the surgery respectively

    72 hours

  • +4 more secondary outcomes
