  1. Global Registry of Acute Coronary EventsAssessing Today’s Practice Patterns to Enhance Tomorrow’s Care Supported by an unrestricted educational grant from sanofi-aventis to the Center for Outcomes Research University of Massachusetts Medical School

  2. 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

  3. 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

  5. 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

  6. Core GRACE Study Design • ~100 hospitals in 14 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
