Key result
Over a 30-year period in Japan, the age-adjusted in-hospital mortality for acute myocardial infarction decreased from 20% in 1979 to 8% in 2008, while the incidence increased from 7.4 to 27.0 per 100,000.
Highlights the importance of assessing temporal trends in the incidence and mortality of acute myocardial infarction in Japan amid lifestyle changes and medical advancements.
cute myocardial infarction (AMI) is a leading cause of death, not only in Japan but also worldwide.In Japan in particular, AMI is becoming an increasingly important disease, primarily because of the progressive westernization of lifestyle habits and the rapid aging of society over the past 50 years.Concomitantly, during the past 2 decades the prevention and treatment of AMI has advanced dramatically, because we treat the involved coronary artery lesions using various interventional strategies. 1 In the current era, when the various factors related to AMI have undergone rapid change, it is becoming increasingly important to assess the temporal trends in AMI in the Japanese population.

Asakura et al. (2009) conducted an editorial in Acute Myocardial Infarction (AMI) (n=22,551). Time period (2008 vs 1979) vs. 1979 was evaluated on Age-adjusted in-hospital mortality. Over a 30-year period in Japan, the age-adjusted in-hospital mortality for acute myocardial infarction decreased from 20% in 1979 to 8% in 2008, while the incidence increased from 7.4 to 27.0 per 100,000.
