NCT03787745

Brief Summary

In a prospective, randomized clinical trial the iPOST2 trial will determine whether ischemic postconditioning reduces reperfusion injury and this will translate into improved clinical outcome of heart failure and death for STEMI patients who present with TIMI0-1 undergoing primary PCI

Outcome Measures

Primary Outcomes (1)

  • All cause mortality or hospitalization for heart failure

    Composite endpoint of all cause mortality or hospitalization for heart failure which ever occur first

    From date of randomization until the date of first documented hospitalization for heart failure or date of death from any cause, whichever came first, assessed up to 280 events have been adjudicated or up to 36 months

Secondary Outcomes (8)

  • All cause mortality

    From date of randomization until the date of first documented death from any cause assessed up to 280 events have been adjudicated or up to 36 months

  • Percentage of patients hospitalized for heart failure

    From date of randomization until the date of first documented hospitalization for heart failure assessed up to 280 events have been adjudicated or up to 36 months

  • Percentage of patients with myocardial infarction

    From date of randomization until the date of first documented hospitalization for heart failure or date of death from any cause, whichever came first, assessed up to 280 events have been adjudicated or up to 36 months

  • Cardiovascular death

    From date of randomization until the date of first documented hospitalization for heart failure or date of death from any cause, whichever came first, assessed up to 280 events have been adjudicated or up to 36 months

  • Percentage of patients with stroke

    From date of randomization until the date of first documented hospitalization for heart failure or date of death from any cause, whichever came first, assessed up to 280 events have been adjudicated or up to 36 months

Study Arms (2)

Ischemic postconditioning

ACTIVE COMPARATOR

In addition to state of the art primary PCI in patients with TIMI0-1 ischemic postconditioning with an adequately sized balloon (60 reperfusion/60 seconds re-occlusion, four cycles) will be performed, however thrombectomy will not be allowed

Procedure: Ischemic postconditioning

Conventional

PLACEBO COMPARATOR

State of the art primary PCI in patients with TIMI0-1 will be performed, however thrombectomy will not be allowed

Procedure: Conventional

Interventions

After 60 seconds of reperfusion, ischemic postconditioning with an adequately sized balloon (60 reperfusion/60 seconds re-occlusion, four cycles) will be performed
