PCI in late-presenting STEMI: how late is too late?

Take Home Messages
  • PPCI is of benefit in patients presenting more than 12 hours post STEMI with evidence of ongoing ischaemia, shock, malignant arrhythmias, or heart failure
  • PCI in patients presenting between 12 and 48 hours appears to reduce overall mortality, and improve LV function
  • PCI in asymptomatic patients with an occluded infarct-related artery beyond 48 hours is not of benefit in the absence of significant angina or inducible ischaemia
