Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to evaluate whether using the the IMPELLA® CP System temporary circulatory assist device for 30 minutes prior to a catheterization procedure has the potential to reduce the damage to the heart caused by a heart attack, compared to the current standard of care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To demonstrate the safety and effectiveness of primary Left Ventricular unloading and a thirty-minutes delay to reperfusion vs. current standard of care in reducing infarct size and heart failure-related clinical events in patients presenting with anterior ST-Elevation Myocardial Infarction.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

A prospective, multicenter, randomized, controlled open-label two-arm trial with an adaptive design
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors
Blinding of the operator and patient is not possible given the nature of the treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental

Subjects randomized to the experimental arm will have their heart unloaded for 30 minutes on the Impella CP® device prior to PCI.

Each site is required to have one "roll-in" per arm to test the study protocol before beginning enrollment.

Group Type EXPERIMENTAL

Impella CP® placement prior to reperfusion with Primary PCI

Intervention Type DEVICE

Subjects randomized to the experimental arm, will undergo Impella CP® placement through a femoral arterial sheath and the Impella device will be activated to unload the left ventricle.

Control

Primary PCI. Each site is required to have one "roll-in" per arm to test the study protocol before beginning enrollment.

Group Type NO_INTERVENTION

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 18-85 years
2. First myocardial infarction
3. Acute anterior STEMI with ≥2 mm in 2 or more contiguous anterior leads or ≥ 4 mm total ST segment deviation sum in the anterior leads V1-V4 AND anterior wall motion abnormality noted on a diagnostic quality left ventriculogram or echocardiogram
4. Patient presents to the enrolling hospital where the index procedure will be performed between 1 - 6 hours after onset of continuous ischemic pain
5. Patient indicated for Primary PCI
6. Patient or the patient's Legally Authorized Representative (where applicable) has signed Informed Consent

Exclusion Criteria

3. Administration of fibrinolytic therapy within 24 hours prior to enrollment
4. Cardiogenic shock defined as: systemic hypotension (systolic BP \<90 mmHg or the need for inotropes/pressors to maintain a systolic BP \>90mmHg) plus one of the following: any requirement for pressors/inotropes prior to arrival at the catheterization laboratory, clinical evidence of end organ hypoperfusion or use of IABP or any other circulatory support device
5. Inferior STEMI or suspected right ventricular failure
6. Any contraindication or inability to place the Impella, including peripheral vascular disease, tortuous vascular anatomy, femoral bruits or absent pedal pulses
7. Severe aortic stenosis
8. Acute cardiac mechanical complication: LV free wall rupture OR Interventricular septum rupture OR Acute mitral regurgitation
9. Suspected or known pregnancy
10. Suspected systemic active infection
11. History or known hepatic insufficiency prior to catheterization
12. On renal replacement therapy
13. COPD with home oxygen therapy or on chronic steroid therapy
14. Known or evidence of prior myocardial infarction, including pathologic Q waves in non-anterior leads
15. Prior CABG or LAD PCI
16. History of heart failure (documented history of EF \<40% or documented hospitalization for HF within one (1) year prior to screening)
17. Prior aortic valve surgery or TAVR
18. Left bundle branch block (new or old)
19. History of stroke/TIA within the prior 3 months, any history of Intracranial Hemorrhage or any permanent neurological deficit
20. History of bleeding diathesis or known coagulopathy (including heparin-induced thrombocytopenia), any recent GU or GI bleed, or will refuse blood transfusions
21. Patient on systemic anticoagulation pre-procedure (including factor Xa inhibitors, thrombin inhibitors, warfarin)

Known contraindication to:
22. Undergoing MRI or use of gadolinium, \[CrCl\<30 ml/min, non-compatible implant, claustrophobia\]
23. Heparin, pork, pork products or contrast media
24. Receiving a drug-eluting stent
25. Participation in the active treatment or follow-up phase of another clinical study of an investigational drug or device which has not reached its primary endpoint.
26. Any organ condition, concomitant disease (e.g., psychiatric illness, severe alcoholism, or drug abuse, severe cancer, hepatic or kidney disease), with life expectancy of ≤2 years or other abnormality that itself, or the treatment of which, could interfere with the conduct of the study or that, in the opinion of the Investigator and/or Sponsor's medical monitor, would pose an unacceptable risk to the patient in the study.
27. Subject has other medical, social, or psychological problems that, in the opinion of the Investigator, compromises the subject's ability to give written informed consent and/or to comply with study procedures, including follow-up CMRs.
28. Subject belongs to a vulnerable population \[Vulnerable patient populations are defined as Individuals with mental disability, persons in nursing homes, children, impoverished persons, homeless persons, nomads, refugees, prisoners, and those permanently incapable of giving informed consent. Vulnerable populations also may include members of a group with a hierarchical structure such as university students, subordinate hospital and laboratory personnel, employees of the Sponsor, and members of the armed forces.

* A pregnancy test will be conducted prior to enrollment if required by Institutional Review Board (IRB), Regional Ethics Board (REB), local Ethics Committee (EC) or competent authority.
