NCT02445885

Brief Summary

Although recommended therapy for patients with ST-segment elevation myocardial infarction is primary PCI, it remains unestablished whether patients with a symptom duration of more 12 hours benefit from acute revascularisation. This study aims to investigate whether acute intervention is superior to subacute intervention in these patients.

Outcome Measures

Primary Outcomes (1)

  • Acute salvage index evaluated by MRI

    MRI within 48 timer after index admission will be used to measure are at risk (AAR, T2-weighted) and acute infarct size (IZ). Acute salvage index is (AAR-IZ)/AAR

    1-2 days

Secondary Outcomes (5)

  • Final infarct size

    3 months

  • Final myocardial salvage index

    1-2 days

  • Acute infarct size

    1-2 days

  • Microvascular obstruction (MVO)

    1-2 days

  • Left Ventricular Ejection Fraction (LVEF)

    1-2 days and 3 months

Other Outcomes (1)

  • Left Ventricular (LV) volumes

    1-2 days and 3 months

Study Arms (2)

Acute PCI

EXPERIMENTAL

Acute re-opening of the occluded coronary artery including premedication as for primary PCI within 12 hours

Procedure: PCI

Subacute PCI

ACTIVE COMPARATOR

Standard subacute re-opening of the occluded coronary artery including premedication as for subacute PCI within 72 hours

Procedure: PCI

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients more than 18 years of age.
  • STEMI \> 12 hours and \< 36 hours.
  • Clinical stable, i.e. no on going angina, hemodynamically stable (systolic BP \> 90) and Killip class \< 3.

You may not qualify if:

  • Clinical instability which requires an acute invasive strategy.
  • Left main occlusion or multivessel disease which requires CABG.
  • Previous Q-wave infarction in the current infarct related artery.
  • Left Bundle Branch Block (LBBB).
  • Severe renal insufficiency.
  • Pacemaker
  • Chronic atrial fibrillation.
  • Previous Coronary Artery Bypass Surgery (CABG).
  • Pregnancy.
  • Other severe illness with life expectancy less than 1 year
