NCT05506449

Brief Summary

The purpose of this study is to assess whether hemodynamic support with an Impella-based treatment strategy initiated prior to percutaneous coronary intervention (PCI) in patients with ST-Segment Elevation Myocardial Infarction (STEMI)-Cardiogenic Shock (CS) improves survival and functional outcomes compared to a non-Impella-based treatment strategy.

Study Arms (2)

Control Arm

ACTIVE COMPARATOR

Subjects randomized to the Control Arm will be treated based on recommendations for cardiogenic shock in the contemporary AHA/ACC/SCAI and ESC Practice Guidelines for STEMI and Heart Failure Management and local standard of care.

Other: Standard of Care

Treatment Arm

EXPERIMENTAL

Subjects randomized to the Treatment Arm will receive hemodynamic support using an Impella-based treatment strategy initiated prior to percutaneous coronary intervention (PCI).

Device: Impella CP®

Interventions

Subjects randomized to the Treatment Arm will undergo Impella CP placement prior to PCI. Right heart catheterization will be performed prior to or immediately after PCI. Use of IABP will not be allowed in the Treatment Arm.

Treatment Arm

This may include inotropes and/or vasopressors. An IABP may or may not be used according to local practice and the specific condition of each individual patient. If an IABP is used, it may be placed prior to or after PCI, and its timing of explant is left to the discretion of the Investigator.

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Cardiogenic shock with onset ≤12 hours after STEMI and prior to index PCI, as defined by having both the following:
  • Persistent SBP \<90 mmHg for ≥30 minutes despite fluid resuscitation or pressors/inotropes required to maintain SBP ≥90 mmHg and
  • Signs of impaired organ perfusion (cool extremities and/or altered mental status)
  • One of the following must be present on a standard 12-lead electrocardiogram (ECG):
  • ST-segment elevation (≥2 mm elevation of ST-segments in ≥2 contiguous leads without left bundle branch block) or
  • Anterior (V1-V4) ST-segment depression ≥2 mm in ≥2 contiguous leads consistent with a possible posterior infarction AND coronary angiogram prior to randomization showing acute total or subtotal occlusion of the proximal circumflex artery or
  • aVR ST-segment elevation ≥2 mm without anterior ST-segment elevation AND coronary angiogram prior to randomization confirming left main culprit lesion
  • NOTE: Patients with isolated RV infarction are excluded from this Protocol. If a patient qualifies with cardiogenic shock with only inferior ST-segment elevation, pre-randomization assessment of LV function must be obtained with either point of care echocardiography or contrast left ventriculography to demonstrate a LVEF ≤40% for the patient to be eligible for randomization.
  • Intended emergent PCI to treat the STEMI
  • Subject is able to and agrees to provide written informed consent. If the subject is unable to be consented because of their extreme illness and a legally authorized representative (LAR) is present, the LAR must agree and provide written informed consent. If the subject is unable to provide consent because of their extreme illness and an LAR is not present, the patient may be randomized under Exception from Informed Consent (EFIC) Guidance

You may not qualify if:

  • High suspicion for isolated right ventricular infarct confirmed with ECG lead V4R
  • Cardiogenic shock with either of the following:
  • High-grade atrioventricular block (heart rate (HR) \<50 bpm)
  • NOTE: If patient is paced, via temporary or permanent pacemaker, and still in shock, they are still eligible
  • Isolated narrow complex supraventricular tachycardia with ventricular response \>170 bpm or ventricular tachyarrhythmia with ventricular response \>150 bpm
  • Known mechanical complications of acute myocardial infarction (AMI) that may cause cardiogenic shock such as free wall rupture, cardiac tamponade, ventricular septal defect or papillary muscle rupture with acute mitral regurgitation
  • Left ventricular function (LVEF \>40%) on echocardiography or LV-gram (if performed) indicating shock due to another cause (e.g., RV infarction as the principal cause of shock, hypovolemia, sepsis or high cardiac output shock)
  • Severe bilateral peripheral arterial disease precluding femoral Impella CP insertion (femoral angiogram required) NOTE: Impella insertion via a non-femoral arterial route is not permitted in this Protocol.
  • IABP, Impella or other mechanical circulatory support already in place for present indication (pre-randomization)
  • Known end-stage renal disease, receiving dialysis
  • Severe aortic stenosis, or moderate or worse aortic regurgitation or prior self-expanding transcatheter aortic valve replacement (TAVR), or surgically placed mechanical valve, if known
  • Acute or chronic aortic dissection, if known
  • Large or mobile LV thrombus, if known
  • Prior PCI for the present infarction
  • Prior PCI or coronary artery bypass graft (CABG) within 1 year, if known
  • +17 more criteria
