[Rapid and secure exclusion of myocardial infarctionwithout ST-segment elevation].

Rapid identification of acute myocardial infarction (MI) is important for the early initiation of evidence-based therapy. In the European Society of Cardiology (ESC) 0/1h-algorithm (also called early-rule-out algorithm) high-sentivity cardiac troponin is measured at admission and one hour later. By using assay-specific cut-off levels patients are triaged to three different groups; "rule-out", "observation" or "rule-in" of acute MI. The ESC 0/1h-algorithm has high diagnostic accuracy and safety to rule out MI. This review summaries the current knowledge and practical use of the new early-rule-out algorithm.
