ST elevation on ECG[1]

New (or increased) and persistent ST-segment elevation in at least two contiguous leads of ≥1 mm in all leads, other than leads V2-V3 where the following cut points apply:[1]

  • ≥2.5 mm in men <40 years old

  • ≥2 mm in men >40 years old

  • ≥1.5 mm in women regardless of age.

Criteria for acute, evolving, or recent MI[3]

Either one of the following criteria:

  1. Typical rise of biomarkers of myocardial necrosis (troponin or creatine kinase-MB) with at least one of the following:

    • Ischaemic symptoms

    • Development of pathological Q waves on ECG

    • ECG changes indicative of ischaemia (ST-segment elevation or depression)

    • Coronary artery intervention (e.g., coronary angiography).

  2. Pathological findings of acute MI.

Criteria for established MI[3]

Any one of the following:

  1. Development of pathological Q waves on serial ECGs. The patient may or may not remember previous symptoms. Biochemical markers of myocardial necrosis may have normalised, depending on the length of time that has passed since the infarct developed.

  2. Pathological findings of a healed or healing MI.

  3. Cardiac magnetic resonance imaging with delayed enhancement imaging showing a classic sub-endocardial or transmural infarct in a coronary artery distribution.
