NCT03238508

Brief Summary

This study will compare the microcirculatory resistance (IMR) of infarct-related artery (IRA) in patients who underwent immediate versus deferred stenting during percutaneous coronary intervention (PCI) for acute myocardial infarction.

Outcome Measures

Primary Outcomes (1)

  • Index of microcirculatory resistance of infarct-related artery

    Measured by pressure and temperature sensors- tipped guide wire

    3 to 5 days after primary reperfusion (TIMI 3 flow achievement) in both groups

Secondary Outcomes (3)

  • The rate of urgent revascularization

    During index hospitalization (intraoperative)

  • Major bleeding

    During index hospitalization (intraoperative)

  • Major adverse cardiac events

    One- year after primary reperfusion

Study Arms (2)

Immediate stenting group

Conventional stenting immediate after the re-opening of infarct-related artery during primary PCI

Deferred stenting group

Elective stenting following cooling down of infarct- related artery for several days after restoration of epicardial coronary blood flow during primary PCI

Procedure: Deferred stenting

Interventions

Previously described

Deferred stenting group

Eligibility Criteria
