Implication
Supports prevention efforts; extends observational trends but leaves causal drivers and long-term effects open.
Key Points
- To evaluate temporal trends in the incidence and short-term fatality rates of acute myocardial infarction subtypes within a community setting.
- Assessed population trends in acute myocardial infarction incidence and short-term case fatality rates within a large community-based cohort.
- Stratified longitudinal data by ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI).
- Overall myocardial infarction incidence decreased significantly after 2000, and STEMI incidence decreased markedly after 1999.
- Short-term case fatality rates declined, driven in part by lower STEMI incidence and decreased post-NSTEMI mortality.

Outcome
Incidence of myocardial infarction (including ST-segment elevation myocardial infarction) and short-term case fatality rateshard clinical
Population-level incidence and short-term case fatality rates of acute myocardial infarction have significantly decreased since 2000, largely driven by a reduction in STEMI incidence.
