Management of acute myocardial infarction with ST-segment elevation

This article gives an update on the management of ST-segment elevation myocardial infarction (STEMI) according to guidelines released in 2012 by the European Society of Cardiology. To ensure a reliable diagnosis the updated universal definition of myocardial infarction will also be covered which is defined by myocardial necrosis. Criteria for diagnosis are a rise or fall of cardiac biomarkers, preferably troponin, in conjunction with symptoms of myocardial ischemia, new repolarisation disorders or left bundle branch block, development of pathological Q-waves, new hypokinesia/akinesia or loss in viability or the detection of intracoronary thrombi during cardiac catheterization or autopsy. The current recommendations for primary diagnosis and treatment by the first medical contact will also be discussed and contains decision-making for the optimal reperfusion strategy. Primary percutaneous coronary intervention remains the preferred reperfusion strategy; however, specifications with respect to time for diagnosis and reperfusion have been introduced. Furthermore, establishing a STEMI network has been emphasized in more detail. Special attention is paid to the new antiplatelet agents and anticoagulation therapy where prasugrel and ticagrelor are currently preferred over clopidogrel.
