ESC/AHA/ACC/WHF classification of MI 2018 [9]

Type 1	Acute atherothrombotic occlusion or mural thrombus with critical flow reduction initiated by plaque rupture or erosion
Type 2	Ischemic injury due to a myocardial oxygen supply-demand mismatch, which is not caused by coronary atherothrombosis (Table 2)
Type 3	Cardiac death in a clinical setting suggestive of ischemic injury (chest pain, ECG changes) but without definitive cardiac biomarker evidence
Type 4	PCI-related ischemic injury < 48 h after procedure. Includes also cases of MI due to late stent thrombosis or restenosis
Type 5	CABG-related ischemic injury < 48 h after the procedure
