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.
Device: Impella CP® placement prior to reperfusion with Primary PCI
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.
No Intervention: Control
Primary PCI. Each site is required to have one "roll-in" per arm to test the study protocol before beginning enrollment.
- Infarct Size [ Time Frame: 3-5 days post-procedure ]Infarct size normalized to the left ventricular mass, evaluated using Cardiac Magnetic Resonance (CMR) imaging
- Infarct Size, as a percent of Left Ventricular Mass [ Time Frame: 3-5 days ]Efficacy- Composite clinical secondary endpoint, Compared between groups in a hierarchical order using the Finkelstein-Schoenfeld statistic.
- Impella CP® related Major Bleeding and Major Vascular complications [ Time Frame: 30 Days ]Efficacy (Cardiogenic Shock)- Composite clinical secondary endpoint. Compared between groups in a hierarchical order using the Finkelstein-Schoenfeld statistic. Secondary Safety (Major Bleeding and Vascular Complications); with pre-specified performance goals.
- Cardiogenic Shock, CV mortality, Heart Failure, LVAD or Heart Transplant and ICD or CRT Placement [ Time Frame: 12 Months ]Efficacy- Composite clinical secondary endpoint. Compared between groups in a hierarchical order using the Finkelstein-Schoenfeld statistic.
