Background • The HORIZONS trial trial provided an opportunity to compare outcomes with primary PCI for STEMI at sites in the United States versus at sites outside the United States. This has not been previously evaluated. • Patients enrolled outside of the United States in Europe, Israel and Argentina (OUS) (n = 2,788) were compared with patients enrolled in the United States (US) (n = 814).

Conclusions • STEMI patients enrolled in the HORIZONS-AMI Trial in the US had a much higher risk profile than patients enrolled outside the US. • HORIZONS patients treated with primary PCI in the US had higher rates of death, death/MI, MACE, major bleeding and NACE compared with OUS patients. • After adjusting for differences in baseline variables, US patients had significantly higher rates of MACE, Major Bleeding and NACE compared with OUS patients. • Both US and OUS patients had lower event rates with bivalirudin compared with IIb/IIIa platelet inhibitors. There were no significant interactions between US vs OUS sites and randomization treatment. Brodie et al ACC 2008
