With the introduction of more sensitive cardiac biomarkers, the European Society of Cardiology (ESC) and the American College of Cardiology (ACC) collaborated to redefine MI using a biochemical and clinical approach, and reported that myocardial injury detected by abnormal biomarkers in the setting of acute myocardial ischaemia should be labelled as MI.

The TIMI risk score, based upon data from 15,000 patients with an ST segment elevation myocardial infarction eligible for fibrinolytic therapy, is a simple arithmetic sum of eight independent predictors of mortality.
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:
