Myocardial infarction redefined - A consensus document of the Joint European Society of Cardiology/American College of Cardiology committee for the redefinition of myocardial infarction

TLDR: Biochemical markers of myocardial necrosis may have normalized, depending on the length of time that has passed since the infarct developed, and one of the following criteria satisfies the diagnosis for established MI: development of new pathologic Q waves on serial ECGs.

Abstract: This document was developed by a consensus conference initiated by Kristian Thygesen, MD, and Joseph S. Alpert, MD, after formal approval by Lars Ryden, MD, President of the European Society of Cardiology (ESC), and Arthur Garson, MD, President of the American College of Cardiology (ACC). All of the participants were selected for their expertise in the field they represented, with approximately one-half of the participants selected from each organization. Participants were instructed to review the scientific evidence in their area of expertise and to attend the consensus conference with prepared remarks. The first draft of the document was prepared during the consensus conference itself. Sources of funding appear in Appendix A. The recommendations made in this document represent the attitudes and opinions of the participants at the time of the conference, and these recommendations were revised subsequently. The conclusions reached will undoubtedly need to be revised as new scientific evidence becomes available. This document has been reviewed by members of the ESC Committee for Scientific and Clinical Initiatives and by members of the Board of the ESC who approved the document on April 15, 2000.
