Transport and centralization of acute coronary syndrome care.

Primary percutaneous coronary intervention (PCI) is the optimal treatment for patients presenting with ST-elevation myocardial infarction (STEMI). But PCI facilities are not widely available, and the majority of patients who receive reperfusion therapy are treated with thrombolytic therapy. However, with significant improvements in the procedural success of PCI, there has been a concomitant reduction in the need for emergency bypass surgery and there is evidence to support primary PCI without on-site cardiac surgical facilities. Others have proposed immediate transfer to a suitable hospital for immediate primary PCI. An alternative treatment strategy is facilitated PCI, which might combine the early benefits of thrombolysis with the higher patency rates and superior clinical outcomes of primary PCI, although this remains unproven. Finally, rescue PCI remains a reasonable treatment option for patients with failed thrombolysis, but there is insufficient evidence to support this option as a preferred treatment strategy for patients with STEMI.
