In acute ST segment elevation myocardial infarction (STEMI), rapid restoration of epicardial coronary blood flow and myocardial perfusion limits infarct size and improves survival. Primary percutaneous coronary intervention (PCI) is superior to systemic fibrinolysis when instantly performed by experienced operators. The "Herzinfarktverbund Essen" (HIVE) is an urban STEMI network supporting direct patient transfer for primary PCI to four PCI centers covering a city area of 600,000 inhabitants. Integrated health care is an optional part of the HIVE allowing for reimbursement of medical innovations such as the evaluation of infarct size and the presence and extent of microvascular obstruction by contrast-enhanced cardiac magnetic resonance (CMR). The aim of this study was to assess the prognostic impact of contrast-enhanced CMR in the patient cohort of a regional STEMI network. ⋯ NR as a correlate of microvascular obstruction remains independently related to prognosis in patients with acute myocardial infarction treated by PCI.

Rapid revascularization of the infarct-related artery importantly affects prognosis in the treatment of acute ST elevation myocardial infarction (STEMI). Treatment results can be improved significantly when a STEMI-specific structure of care is created and when systematic quality improvement measures are implemented. The necessary structural measures include establishing or participating in myocardial infarction networks. ⋯ The structures and processes outlined above can and should be applied broadly. The necessary resources will need to be provided through political and societal consensus. The multicenter FITT-STEMI project ("Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction") is currently pursuing such an approach.
