About this trial

This is an interventional treatment trial for ST-elevation Myocardial Infarction focused on measuring STEMI

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age ≥ 18 years
  • Signed Informed Consent
  • Acute anterior STEMI with ≥2 mm of ST-segment elevation in 2 or more contiguous anterior leads or ≥ 4 mm in total in the anterior leads, OR, Large Inferior STEMI with ≥2 mm of ST-segment elevation in 2 or more inferior leads AND EITHER ≥1 mm ST-segment elevation in V1 OR ≥1 mm of ST-segment depression in ≥2 contiguous anterior leads (V1-V3)
  • Primary PCI performed within 5 hours of the onset of symptoms
  • Patient undergoing emergent primary PCI of one culprit lesion in one major native epicardial coronary vessel
  • Successful revascularization of the culprit native coronary artery with TIMI Flow Grade of 3 at the end of PCI

Exclusion Criteria:

  • Cardiac arrest requiring CPR within 24 hours prior to enrollment

  • Prior coronary artery bypass graft surgery
  • Known mural thrombus in the left ventricle or contraindication to left ventriculography
  • Presence of a mechanical aortic valve
  • Documented presence of moderate to severe aortic stenosis or moderate to severe aortic insufficiency.
  • Known history of severe kidney dysfunction.
  • Known contraindication to MRI (implanted metallic or magnetically activated device; claustrophobia, inability to hold breath for 15 seconds).
  • History of recent (within 1 month) stroke or TIA
  • History of bleeding diathesis or known coagulopathy (including heparin-induced thrombocytopenia), or will refuse blood transfusions.

  • Contrast media Participation in the active treatment or follow-up phase of another clinical study of an investigational drug or device.
  • Severe peripheral arterial obstructive disease that would preclude the IMPELLA® System placement
  • Requirement to treat two or more culprit vessels during primary PCI, or plan for staged coronary revascularization (PCI or CABG) within the next 30 days.
  • Inability to place Impella within 6 hours of the onset of symptoms, should patient be randomized to this arm.

    Brief Summary
    A prospective, randomized, controlled multi-site feasibility trial to assess the potential role of the IMPELLA® 2.5 System in reducing infarct size in patients with ST-elevation myocardial infarction (STEMI)
    Detailed Description
    The primary objective of this study is to evaluate whether the adjunctive use of the IMPELLA® 2.5 System for 24 hours following primary PCI for STEMI has the potential to limit the infarction of at-risk myocardium compared to primary PCI with routine post-PCI care (standard of care). This study is a feasibility study. Therefore, the principal objective is to identify trends in cardiac magnetic resonance imaging (MRI)-based efficacy outcomes between the randomized treatment arms (Impella arm compared standard of care.
