Criteria for acute, evolving or recent MI
Either one of the following criteria satisfies the diagnosis
for an acute, evolving or recent 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;
- (c) ECG changes indicative of ischemia (ST segmen elevation or depression); or
- (d) coronary artery intervention (e.g., coronary angioplasty).
--------
Criteria for established MI
Any one of the following criteria satisfies the diagnosis
for established MI:
(1) Development of new pathologic Q waves on serial
ECGs. The patient may or may not remember
previous symptoms. Biochemical markers of myocardial
necrosis may have normalized, depending on the length of time
that has passed since the infarct developed.
(2) Pathologic findings of a healed or healing MI.
Elevations of creatine-kinase-MB and mortality in patients with
acute coronary syndromes without ST-segment elevation.
