Key result
The age-adjusted incidence rate of acute myocardial infarction was 61.9 per 100,000 person-years, with age-adjusted in-hospital mortality remaining high at 12.3% for STEMI compared to 5.8% for NSTEMI.
Why the study?
The study aimed to investigate the incidence and in-hospital mortality of AMI conforming to the Universal Definition of Myocardial Infarction in a population-based registry.
Population
1,587 patients diagnosed with AMI in the Shiga Prefecture
Comparison
STEMI vs NSTEMI
Design
Multicenter population-based registry
Follow-up
In-hospital

Japanese registry data highlight persistent AMI burden and STEMI mortality gap; extends universal definition application in cohorts but leaves practice implications open.
Observational (n=1,587)
Yes
Absolute Event Rate: 12.1% vs 5.7%
p-value: p=<0.001
The application of the Universal Definition of Myocardial Infarction in a Japanese population-based registry revealed an age-adjusted AMI incidence of 61.9 per 100,000 person-years and highlighted persistently high in-hospital mortality for STEMI patients.
Sawayama et al. (2022) conducted an observational in Acute Myocardial Infarction (n=1,587). ST-elevation myocardial infarction (STEMI) vs. Non-ST-elevation myocardial infarction (NSTEMI) was evaluated on In-hospital mortality (p=<0.001). The age-adjusted incidence rate of acute myocardial infarction was 61.9 per 100,000 person-years, with age-adjusted in-hospital mortality remaining high at 12.3% for STEMI compared to 5.8% for NSTEMI.
