Temporal Trends in Acute Myocardial Infarction Incidence and Mortality Between 2006 and 2016 in Tokyo - Report From the Tokyo CCU Network.

BACKGROUND

Temporal trends in the incidence and mortality of acute myocardial infarction (AMI) have not been fully clarified in Japan.

METHODS AND RESULTS

The Tokyo CCU network collects information every 3 months regarding the number of AMI cases, age of patients and in-hospital mortality. Age-adjusted hospitalized AMI numbers were unchanged from 2006 to 2016 (40.7/100,000 persons/year in 2016). Annual age-adjusted in-hospital mortality decreased slightly (5.8% in 2006 to 5.2% in 2016).

CONCLUSIONS

A steady trend of AMI incidence was observed over the past 11 years in the Tokyo metropolitan area. In-hospital mortality decreased slightly but significantly, with the establishment of primary percutaneous coronary intervention.
