12 Universal Definition of Myocardial Infarction Acute myocardial infarction is defined as myocardial cell death due to prolonged myocardial ischaemia Thygesen K and the Joint ESC/ACCF/AHA/WHF Task Force for the Universal Definition of Myocardial Infarction Eur Heart J 2012;33:

13 Universal Definition of Myocardial Infarction Detection of a rise and/or fall of cardiac biomarker values (preferably cardiac tro ponins) with at least one value above the 99th percentile upper reference limit ( URL) and with at least one of the following: Ischaemic symptoms ECG changes of new ischaemia (new ST-T changes or new LBBB) Development of pathologic Q waves in the ECG Imaging evidence of new loss of viable myocardium or new regional wall moti on abnormality Identification of an intracoronary thrombus by angiography or autopsy Thygesen K and the Joint ESC/ACCF/AHA/WHF Task Force for the Universal Definition of Myocardial Infarction Eur Heart J 2012;33:
