The cumulative incidence is stratified by the underlying cause of type 2 myocardial infarction. Patients with bradyarrhythmia or the subgroup others had the best prognoses. The subgroups type 1 myocardial infarction (T1MI), hypertension, and tachyarrhythmia had more favorable prognoses than multiple triggers, including hypotension, hypoxemia, or anemia. Multiple triggers defined as more than 1 of the mentioned reasons; others included coronary artery spasm, coronary embolism, and coronary artery dissection.
