Up to 80% of patients will have at least one troponin sent ( Gabrielli 2022 ). Type 2: MI secondary to ischaemia, but not related to coronary atherosclerosis.

Emergency physicians have recognized for some time that there are many occlusions of the coronary arteries that do not present with classic STEMI criteria on the ECG. In October 2022, the American College of Cardiology released an updated expert consensus decision regarding the evaluation of chest pain in the emergency department.
