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

5. Study Description
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.
