Definition of MI
Criteria for 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: | |
• Ischaemic symptoms | |
• Development of pathologic Q-waves on electrocardiography | |
• Electrocardiography changes indicative of ischaemia (ST-segment elevation or depression) | |
• Coronary artery intervention | |
2 | Pathologic findings of an acute MI |
Criteria for established MI | |
1 | Development of new pathologic Q-waves on serial electrocardiographs. 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 |
