Key result
Off-hours STEMI presentation is linked to ~51% lower odds of timely reperfusion.
Why the study?
Delays to reperfusion therapy for STEMI and factors associated with prolonged delays were not well described in Quebec hospitals in 2003.
What are the delays to reperfusion therapy and factors associated with prolonged delays in patients with STEMI?
Population
1189 consecutive STEMI patients admitted to 17 hospitals in Quebec in 2003
Comparison
Fibrinolytic therapy vs primary PCI at initial hospital vs primary PCI after interhospital transfer
Design
Cohort study

STEMI reperfusion delays in off-hour or transfer cases merit system review; leaves open whether targeted interventions can improve timeliness.
Cohort (n=1,189)
Yes
What are the delays to reperfusion therapy and factors associated with prolonged delays in patients with STEMI?
Odds Ratio: 0.49
Many STEMI patients in Quebec in 2003 experienced delays to reperfusion therapy beyond recommended times, highlighting the need to reorganize pre- and in-hospital care.
Huynh et al. (2006) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=1,189). Presentation outside daytime working hours vs. Presentation during daytime working hours was evaluated on Receiving reperfusion therapy within current recommended times (OR 0.49). Patients with STEMI presenting outside daytime hours, receiving primary PCI, or requiring interhospital transfer were less likely to receive timely reperfusion therapy (ORs 0.49, 0.56, and 0.15).
