ST-Elevation Myocardial Infarction (STEMI)

Publication Date: January 1, 2013

Key Points

Key Points

  • Systems of care should be established in each community to care for patients with ST-Elevation Myocardial Infarction (STEMI) with the ultimate goal of reducing total ischemic time between symptom onset and reperfusion.
  • Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for patients with STEMI when it can be done in a timely fashion (ie, within 2 hours of first medical contact) by expert operators.
  • Following delivery of fibrinolytic therapy when indicated, patients should be transferred to a PCI-capable center, even if clinically stable with signs of successful reperfusion.
  • Non-infarct artery PCI, when indicated, should be deferred to a time remote from primary PCI in the absence of shock or severe heart failure.
