A new, precise definition of acute myocardial infarction

Abstract

Several international cardiovascular societies have revised their diagnostic criteria for acute myocardial infarction (MI) (J Am Coll Cardiol 2007; 50:2173-2188). The cornerstone of diagnosis remains a high level of clinical suspicion, serial electrocardiograms, and troponin levels. This article reviews the new definition and the appropriate clinical tools necessary to diagnose acute MI accurately.
