Abstract:
OBJECTIVES:The aim of this study was to determine the impact of delay to angioplasty in patients with acute coronary syndromes (ACS). BACKGROUND:There is a paucity of data on the impact of delays to percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) undergoing an invasive management strategy. METHODS:Patients undergoing PCI in the ACUITY (Acute Catheterization and Urgent Intervention Triage strategY) trial were stratified according to timing of PCI after clinical presentation for outcome analysis. RESULTS:Percutaneous coronary intervention was performed in 7,749 patients (median age 63 years; 73% male) with NSTE-ACS at a median of 19.5 h after presentation (<8 h [n=2,197], 8 to 24 h [n=2,740], and >24 h [n=2,812]). Delay to PCI>24 h after clinical presentation was significantly associated with increased 30-day mortality, myocardial infarction (MI), and composite ischemia (death, MI, and unplanned revascularization). By multivariable analysis, delay to PCI of >24 h was a significant independent predictor of 30-day and 1-year mortality. The incremental risk of death attributable to PCI delay>24 h was greatest in those patients presenting with high-risk features. CONCLUSIONS:In this large-scale study, delaying revascularization with PCI>24 h in patients with NSTE-ACS was an independent predictor of early and late mortality and adverse ischemic outcomes. These findings suggest that urgent angiography and triage to revascularization should be a priority in NSTE-ACS patients.
