Implications of Misclassification of Type 2 Myocardial Infarction on Clinical Outcomes
Abstract
Background
Patients with type 2 myocardial infarction (MI) are often classified under the diagnosis of non–ST-segment–elevation MI (NSTEMI) despite the significant differences in clinical characteristics, management, and outcomes between type 2 MI and type 1 NSTEMI. This may have significant implications that can lead to inaccurate assessment of quality measures by MI quality review programs.
