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

Abstract

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.

The Trend in Incidence and Case-fatality of Hospitalized Acute Myocardial Infarction Patients in Korea, 2007 to 2016

“…Therefore, it can be inferred that the improvement in the analytic performance of troponin assays and the change of definition for AMI are among the causes for the trend seen in the incidence rate. Our inference is convincing because recent trends in the incidence of AMI in other countries6782425 tend to be similar to that seen in this study. Some studies have shown a large decrease in the incidence rate before 2010 or 2011; however, thereafter the incidence rate has shown a relatively small decrease or has remained steady 345.…”

“…Some studies have shown a large decrease in the incidence rate before 2010 or 2011; however, thereafter the incidence rate has shown a relatively small decrease or has remained steady 345. Studies from Singapore,6 Poland25 and Japan8 have reported a slight increase in the rates again from 2011, like in this study. Despite the effect of introduction of hs-cTn and the new definition of AMI, Korean health providers should change the preventive strategies to decrease the incidence of AMI as it has remained steady since 2011.…”

“…Many countries, including the Asian countries, have reported on recent trends (since 2010) in the incidence rate of CVDs 3456789. However, there has been little research on the incidence of CVDs in Korea since 2010 10.…”

Impact of body temperature at admission on inhospital outcomes in patients with takotsubo syndrome: insights from the Tokyo Cardiovascular Care Unit Network Registry

“…The details of the Tokyo CCU Network Registry have been described elsewhere. 8, 15 TTS was diagnosed based on the revised Mayo Clinic criteria 16 by attending physicians at 71 participating acute cardiovascular care hospitals. Because data on BT started to be collected in the registry from 2013, data on patients hospitalised with TTS from January 2013 to December 2015 were used for the present study.…”

“…High BT was defined according to the World Health Organization’s definition of fever. 17 As there is no generally accepted definition of hypothermia on the basis of axillary temperature, 18–20 we defined low BT as an axillary temperature below 36.0°C in this study.…”
