Primary Outcome Measures:
  • Composite rate of 10 major adverse events including death; MI;Stroke or TIA; and repeat revascularization. [ Time Frame: 30 days +/- 10 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Maximum CPO decrease from baseline.Rate of in hospital major events compared between the IMPELLA and IABP. [ Time Frame: In hospital events ] [ Designated as safety issue: Yes ]

Enrollment: 452
Study Start Date: October 2007
Estimated Study Completion Date: September 2011
Estimated Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IMPELLA LP 2.5 Device: IMPLELLA LP 2.5
Insertion of the LP 2.5 IMPELLA circulatory support system that can be placed across the aortic valve using a single femoral site. The device pumps blood from the left ventricle into the ascending aorta at 2.5 L/min.
Active Comparator: IABP Intra-aortic balloon pump Device: IABP Intra-aortic balloon pump
IABP uses counterpulsation to provide 0.2L/min coronary flow
