Abstract:
Objective To understand the incidence trend of acute myocardial infarction (AMI) death in Yangpu district of Shanghai from 2010 to 2021, analyze the impact of AMI on life expectancy, and provide evidence for AMI prevention and control.
Methods The death cause surveillance data and demographic data of residents were collected in Yangpu district from 2010 to 2021, and the mortality rate, standardized mortality rate, life expectancy, cause-adjusted life expectancy (CELE), years of growth in cause-adjusted life expectancy (PGLEs), and loss of life rate of AMI were calculated. Software Joinpoint 4.9 was used to calculate the average annual percentage change (AAPC) and annual percentage change (APC) of AMI mortality for the analyses on the AMI mortality rate, life expectancy, CELE, PGLEs and loss of life rate.
Results From 2010 to 2021, the standardized mortality rate of AMI showed a downward trend in Yangpu (AAPC=−2.72%, t=−4.874, P=0.001), the standardized mortality rate was always higher in men (16.28/100 000) than in women (11.32/100 000). The proportion of AMI death in cardio/cerebrovascular death showed a downward trend (AAPC=−3.56, t=−6.124, P<0.001), from 8.77% in 2010 to 5.84% in 2021. Compared with 2010, the life expectancy of local residents increased by 1.98 years in Yangpu district in 2021, the CELE of AMI increased by 1.96 years, and the PGLEs decreased by 0.02 years, and the loss of life rate decreased by 0.04%.
Conclusion The standardized mortality rate of AMI showed a downward trend in Yangpu district from 2010 to 2021. Men and elderly people are the key populations in the prevention and control of AMI.
