What is GRACE? Global Registry of Acute Coronary Events • Largest multinational registry covering the full spectrum of ACS • Generalizable patient inclusion criteria • In-hospital and 6-month follow-up • Representative of the catchment population: (clusters of hospitals) • Full spectrum of hospitals and facilities • Training, audit and quality control
International Scientific Advisory Committee International Advisory Committee ‘Americas’ clusters Chair: JM Gore ‘European’ clusters Chair: KAA Fox 8 advisors 8 advisors 40 subsite cardiologists 40 subsite cardiologists
Scientific Advisory Committee Co-Chairs Keith AA Fox, UK Joel M Gore, USA Publications Kim A Eagle, USA Co-ChairsPh Gabriel Steg, France Study Co-ordination Fred Anderson, University of Massachusetts Argentina Enrique Gurfinkel Australia/New Zealand David Brieger Belgium Frans J Van de Werf Brazil Álvaro Avezum Canada Shaun Goodman Germany Dietrich C Gulba Italy Giancarlo Agnelli France Gilles Montalescot Ph Gabriel Steg Poland Andrzej Budaj Spain José López-Sendón United Kingdom Keith AA Fox Marcus Flather United States Frederick A Anderson Kim A Eagle Robert J Goldberg Joel M Gore Christopher B Granger Brian M Kennelly
Objectives of GRACE • Identify opportunities to improve the quality of care for patients with ACS • Describe diagnostic & treatment strategies, & hospital & post-discharge outcomes • Develop hypotheses for future clinical research • Disseminate findings to a wider audience
Core GRACE Study Design • ~100 hospitals in 13 countries • Europe, North & South America, Australia, New Zealand • Population-based clusters with community hospitals and referral centres • First 10-20 consecutive cases per centre/month: qualifying symptoms PLUS evidence of CAD • Random audit of all centres: 3 year cycle
