Temporal Trends in the Incidence and Clinical Features of Acute Myocardial Infarction in a Japanese Rural Area From 2006 to 2014
2017
Recent temporal trends in the incidence and clinical features of acute myocardial infarction (MI) in the Japanese population are not well known.Methods and Results:This study used comprehensive registration for first-ever MI during the 9-year period from 2006 to 2014 in a rural area of northeastern Japan. The study period was divided into three 3-year terms (T1, 2006-2008; T2, 2009-2011; T3, 2012-2014). During the study period, a total of 814 patients with MI were registered. Although the age-adjusted incidence rate (100,000 person-years) in the middle-aged group (<70 years) was relatively stable, the rate for the elderly group (≥70 years) in T3 was significantly lower than that in T1 in both men (368 vs. 279; P<0.01) and women (204 vs. 108; P<0.01). In the general population of the study area, the rate of prescribed anticholesterol drugs was significantly increased during the study period, especially in the elderly population (P<0.01). From a clinical perspective, although the performance rate of primary percutaneous coronary intervention significantly increased with a shortened duration of hospital stay, the in-hospital mortality rate, especially in the elderly, did not significantly decrease during the study period.The present study is the first to demonstrate a decreased age-adjusted incidence of MI during the period from 2006 to 2014 in a Japanese rural population, especially in the elderly.
