Trends and Inequalities in the Incidence of Acute Myocardial Infarction among Beijing Townships, 2007–2018

Abstract

Acute myocardial infarction (AMI) poses a serious disease burden in China, but studies on small-area characteristics of AMI incidence are lacking. We therefore examined temporal trends and geographic variations in AMI incidence at the township level in Beijing. In this cross-sectional analysis, 259,830 AMI events during 2007–2018 from the Beijing Cardiovascular Disease Surveillance System were included. We estimated AMI incidence for 307 consistent townships during consecutive 3-year periods with a Bayesian spatial model. From 2007 to 2018, the median AMI incidence in townships increased from 216.3 to 231.6 per 100,000, with a greater relative increase in young and middle-aged males (35–49 years: 54.2%; 50–64 years: 33.2%). The most pronounced increases in the relative inequalities was observed among young residents (2.1 to 2.8 for males and 2.8 to 3.4 for females). Townships with high rates and larger relative increases were primarily located in Beijing’s northeastern and southwestern peri-urban areas. However, large increases among young and middle-aged males were observed throughout peri-urban areas. AMI incidence and their changes over time varied substantially at the township level in Beijing, especially among young adults. Targeted mitigation strategies are required for high-risk populations and areas to reduce health disparities across Beijing.

Association of extreme precipitation with hospitalizations for acute myocardial infarction in Beijing, China: A time-series study

“…As one of the most populous cities in China, Beijing shoulders a huge burden of AMI, with an incident rate of 231.6 per 100,000 in 2016–2018 ( 26 ). Moreover, an upward tendency of extreme precipitation was observed in Beijing and China under the scenario of global warming ( 27 , 28 ).…”

A novel lncRNA-miRNA-mRNA triple network identifies lncRNA XIST as a biomarker for acute myocardial infarction

“…Nevertheless, AMI is still the main cause of death in patients with CAD worldwide. AMI is responsible for significant patient morbidity and mortality, especially in China, where these rates have been increasing annually [ 3 , 4 ]. Epidemiological studies related to AMI have shown that male sex, hyperlipidaemia, smoking, stress, diabetes, hypertension, age, obesity, family history and a sedentary lifestyle all culminate in the development of AMI [ 5 ].…”

Driving Time to the Nearest Percutaneous Coronary Intervention-Capable Hospital and the Risk of Case Fatality in Patients with Acute Myocardial Infarction in Beijing

“…Although more than 70% of patients in urban areas lived within a 15-min drive to a PCI hospital in 2019, approximately 70% of peri-urban patients had a drive time of more than 15 min. Additionally, our previous work showed that rapid increases in AMI incidence were particularly evident in Beijing’s peri-urban areas [ 29 ]. These findings allow for the identification of within-city health care disparities to inform policy-making and cost-effective allocation of health resources.…”
