Implications of troponin testing in clinical medicine

Table 2 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
