Brief Summary:
Subjects with anterior acute STEMI who receive an IABC before primary PCI will have decreased MI size.

Condition or disease Intervention/treatment Phase
Acute Myocardial Infarction (AMI) Device: Counterpulsation with IAB Phase 4

Detailed Description:
Post clearance device study in which subjects with acute MI will be randomized 1:1 to either receive IAB or to receive standard of care without IAB before mechanical reperfusion. Subjects will be followed throughout their hospital stay and at 30 days.

Other Name: CS100 & CS300 IAB Linear 7.5F Fidelity 8.0 F Sensation 7.0 F

Primary Outcome Measures :
  1. To determine whether IABC before mechanical reperfusion decreases myocardial infarct (MI) size. [ Time Frame: 3-5 days ]

Secondary Outcome Measures :
  1. To determine the effect of IABC before mechanical reperfusion on post PCI cardiovascular function and major adverse cardiac events (MACE) (ie, death, reinfarction, and CHF) at 30 days and 6 months. [ Time Frame: 30 days and 6 months post randomization ]
