Myocardial Infarction Redefined: Role of Cardiac Troponin Testing

Abstract
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.
