Regional systems-of-care for primary percutaneous coronary intervention in ST-elevation myocardial infarction

ST-elevation myocardial infarction (STEMI) is a critical, time-dependent condition requiring immediate reperfusion of the coronary arteries to minimize mortality and morbidity. The preferred method of revascularization is a primary percutaneous coronary intervention (PCI) if this can be performed in a timely manner. This requires an effective and well-organized setup from symptom onset to revascularization. Such regional networks for the diagnosis and treatment of STEMI patients have been proven to be very effective in achieving the treatment goals stipulated by the international guidelines. Several trials have provided evidence that prehospital ECG recording and early diagnosis combined with direct referral to a primary PCI center reduces treatment delay considerably. In-hospital awareness with early notification of the PCI operator and technicians and admission directly to the catheterization laboratory also reduces time to treatment. There is solid evidence that the reduction in treatment delay achieved by dedicated STEMI networks is associated with a lower mortality and morbidity. Regional STEMI networks are now implemented in many countries with highly varying geographical challenges and healthcare systems, allowing patients everywhere to receive optimal treatment with primary PCI.
