Temporal trends in hospitalization for acute myocardial infarction between 2004 and 2011 in Kumamoto, Japan.
BACKGROUND
The Kumamoto Acute Coronary Events Study explored trends for acute myocardial infarction (AMI).


RESULTS
The number of people of advanced age in Kumamoto Prefecture has gradually increased. In 2004-2011, 8,131 AMI patients were registered. Although the age-adjusted AMI incidence in men decreased from 93.1 in 2004 to 70.7 in 2011 (P=0.0294), the age-adjusted in-hospital cardiac death rate was maintained at ~7%; however, the all-cause mortality and noncardiac death rate increased and appeared to be related.


CONCLUSIONS
A steady trend of decreasing AMI incidence was observed. Urgent measures should be established against non-cardiac mortality in this era of an aging population.
