Third Universal Definition of MI Is a Charm


The consensus document was developed by a 52-member task force that represented four societies: theAmerican College of Cardiology (ACC), the American Heart Association (AHA), the European Society of Cardiology (ESC), and the World Heart Federation (WHF).


This updated document includes criteria for defining acute MI after different procedures.
MI related to PCI is defined as an elevation of cardiac troponin levels that is greater than five times the 99th percentile upper reference limit in patients with normal baseline troponin levels or a more than 20% rise in troponin in patients with elevated and stable or falling troponin levels.
MI related to CABG is defined as troponin values greater than 10 times the 99th percentile upper reference limit during the first 48 hours after CABG in patients with normal baseline troponin levels.
The consensus statement also defines MI associated with stent thrombosis.
