Why the study?
The study was conducted to increase clinical research observational evidence on type 2 myocardial infarction by comparing its characteristics and long-term outcomes, including MACE and mortality, with type 1 myocardial infarction.
Do long-term clinical outcomes (MACE and mortality) differ between type 1 and type 2 myocardial infarction in patients undergoing angiography?

Design
Nationwide prospective cohort registry study
Follow-up
≥3 years

Differentiating T2MI from T1MI may refine post-AMI prognostication; leaves open etiology-specific interventions pending randomized trials.
Do long-term clinical outcomes (MACE and mortality) differ between type 1 and type 2 myocardial infarction in patients undergoing angiography?
In patients undergoing angiography for AMI, those with type 2 MI have similar MACE rates but higher total and non-cardiac mortality compared to type 1 MI at 3 years.
