Prognostic Impact of Contrast-Enhanced CMR Early after Acute ST Segment Elevation Myocardial Infarction (STEMI) in a Regional STEMI Network

摘要

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.
