Management and outcomes of patients with acute coronary syndromes in Australia and New Zealand, 2000-2007

OBJECTIVES To describe temporal trends in the use of evidence-based medical therapies and management of patients with acute coronary syndromes (ACS) in Australia and New Zealand. DESIGN, SETTING AND PARTICIPANTS Our analysis of the Australian and New Zealand cohort of the Global Registry of Acute Coronary Events (GRACE) included patients with ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation ACS (NSTEACS) enrolled continuously between January 2000 and December 2007 from 11 metropolitan and rural centres in Australia and New Zealand. RESULTS 5615 patients were included in this analysis (1723 with STEMI; 3892 with NSTEACS). During 2000-2007 there was an increase in the use of statin therapy, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and thienopyridines (P < 0.0001 for each). Among patients with STEMI, there was an increase in emergency revascularisation with PCI (from 11% to 27% [P
