To the Editor Almost 10 years since the Global Task Force introduced a classification of myocardial infarction by etiology, clinicians continue to debate the criteria and value of the diagnosis of type 2 myocardial infarction. Nagele1 suggests the definition should be revised and that the diagnosis of myocardial infarction be restricted to patients in which myocardial ischemia and necrosis occur as a consequence of acute coronary artery occlusion. He suggests the term acute myocardial injury should be used in patients in which injury is due to other causes of myocardial oxygen supply-demand imbalance, irrespective of whether this is associated with myocardial ischemia. This term would encompass those patients currently classified as having type 2 myocardial infarction.
