Median age was 60 years and 87% were males. ST\u2010elevation myocardial infarction accounted for 84% of presentations, and 29% were complicated by cardiac arrest. The majority of patients treated were in SCAI\u2010CSWG stage D (52%), and stage C (26%) shock. Upstream Impella prior to PCI occurred in 84% of patients. The 30\u2010day survival rate was 74%. An adverse event occurred in 39% of patients. Device\u2010related complications were due to hemolysis (32%) and arrhythmia (3%). Escalation of MCS support was required in five patients (16%). Multivariate analysis identified patients requiring transfer to the hub center prior to revascularisation as an independent predictor of mortality (OR 13.2 [1.34\u2013129.3] <jats:italic>p<\/jats:italic>\u2009=\u20090.027).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In this first protocolised hub\u2010and\u2010spoke model of care for AMICS supported by planned upstream use of Impella in Australia, 30\u2010day survival was high compared to published historical rates.
