Description
As we move into the new Millennium, "the times they are a changin" regarding the diagnostic criteria used to rule in and rule out acute myocardial infarction (AMI) (1). The purpose of this editorial is to comment on the new cardiology guidelines for the redefinition of AMI and unstable angina, as well as to compare them with previously published laboratory medicine recommendations. Some of the new recommendations made by clinical groups may appear to be in conflict with those published previously by laboratory medicine groups; thus, we document the chronology and evolution of all guidelines on the use of cardiac markers. Consensus documents recently published by the European Society of Cardiology (ESC), the American College of Cardiology (ACC), and the American Heart Association (AHA) make specific recommendations on the use of biomarkers for the detection of myocardial infarction (MI) (2-5). The redefined criteria used to classify acute coronary syndrome (ACS) patients presenting with ischemic symptoms as acute, evolving, or recent MI are heavily predicated on an increased serum/plasma cardiac troponin (I or T) concentration (2-4). Furthermore, in the new ACC/AHA guidelines for management of patients with unstable angina and non-ST-segment elevation MI (NSTEMI), an increased cardiac troponin value establishes the diagnosis of NSTEMI, whereas a normal cardiac troponin value establishes the diagnosis of unstable angina in ACS patients with ischemic discomfort (5).
