What is a type 2 myocardial infarction: How is it recognized and what should one do to establish that diagnosis?

Abstract

In the 2007 Task Force for the Universal Definition of Myocardial Infarction document, published simultaneously in the Journal of the American College of Cardiology, the European Heart Journal, and Circulation, five subcategories of myocardial infarction (MI) were established (Thygesen et al., J Am Coll Cardiol 50:2173-2195, 2007). The 2007 document was an updated revision of the original document from this group that had first been published in 2000 (Alpert et al., J Am Coll Cardiol 36:959-969, 2000). As noted above, in this second communication the task force defined five subtypes of MI which were retained with modest changes in the 2012 revision (Thygesen et al., Eur Heart J 33:2551-2567, 2012).
