89 TH ANNUAL MEETING MAY 9–MAY 13, 2009BOSTON, MASSACHUSETTSreceived a long term VAD, and 18% (n = 47) underwent heart transplantation.Device-specific survival is demonstrated in figure 1. The AMI indication wasindependently associated with increased in-hospital mortality (HR 2.56, 95% CI(1.01–6.50)). Male gender (HR 0.70 95% CI (0.48–0.99)), support greater than 5days (HR 0.62 95%CI (0.43–0.88)), and receiving a long-term VAD (HR 0.55 95%CI(0.34–0.89)) were independently associated with lower mortality.CONCLUSION: Reasonable survival can be expected for patients requiring temporarycirculatory support with a variety of devices. Acute MI was an independentpredictor of in-hospital mortality. Multi-center data is needed to better understandpredictors of mortality following acute circulatory support.66
