Delays to reperfusion therapy in acute ST-segment elevation myocardial infarction: results from the AMI-QUEBEC Study.

چکیده
BACKGROUND Through the AMI-QUEBEC Study we sought to describe delays to reperfusion therapy for ST-segment elevation myocardial infarction (STEMI) and to identify factors associated with prolonged delays. METHODS We reviewed the charts of all consecutive patients with STEMI admitted to 17 hospitals in the province of Quebec in 2003 to obtain data on the time from presentation to reperfusion therapy. Data were available for 1189 (83.0%) of 1432 patients. RESULTS The median delay to reperfusion therapy was 32 minutes (first and third quartile [Q1, Q3] 20, 49) for 535 patients who received fibrinolytic therapy, 109 minutes (Q1, Q3 79, 150) for 455 patients who underwent primary percutaneous coronary intervention (PCI) at the initial hospital of presentation and 142 minutes (Q1, Q3 115, 194) for 199 patients who underwent primary PCI after an interhospital transfer. Patients who presented outside daytime working hours, those who received primary PCI and those who required interhospital transfer for primary PCI were less likely to receive reperfusion therapy within current recommended times (odds ratios [ORs] 0.49, 0.56 and 0.15, respectively). Increased age was associated with prolonged delays only among patients who received fibrinolytic therapy (OR for each 10-year increase in age 0.95, 95% credible interval [CrI] 0.93-0.99 for fibrinolytic therapy and 0.99, 95% CrI 0.95-1.05, for primary PCI). INTERPRETATION In 2003, many patients with STEMI in Quebec were not treated within the recommended times. Delays may be reduced by reorganizing pre-and in-hospital care for patients with STEMI to expedite delivery of reperfusion therapy.
