Keywords:

Criteria for acute, evolving or recent myocardial infarction (MI) acute, evolving or recent myocardial infarction (MI)
1. Typical rise and gradual fall (troponin) or more rapid rise and
fall (CK-MB) of biochemical markers of myocardial necrosis with at
least one of the following: a) ischemic symptoms; b) development
of pathologic Q waves on the ECG; e) ECG changes indicative of
ischemia (ST segment elevation or depression); d) coronary artery
intervention (e.g., coronary angioplasty).
2. Pathologic fi ndings of an acute MI.
