Analysis of the trend of death and potential life loss of acute myocardial infarction in Nanning residents, 2015-2023.

Objective To analyze the trend of acute myocardial infarction mortality and potential life loss among residents in Nanning City from 2015 to 2023, and provide a basis for formulating chronic disease prevention and control policies. Methods To collate the death cause monitoring data of the whole population in Nanning City. Crude mortality, standardized mortality, age-specific mortality, composition ratio, potential years of life lost (PYLL%), standardized years of life lost (SPYLL%) and average years of life lost (AYLL) were calculated. Joinpointlog-linear regression model was used for trend analysis. Results From 2015 to 2023, a total of 38 870 deaths from acute myocardial infarction were reported in 12 counties (cities, districts) of Nanning City, including 22 566 males and 16 304 females. The crude mortality rate was 59.84/100 000, and the standardized mortality rate was 53.70/100 000. The crude mortality rate and standardized mortality rate both showed a stable trend, with AAPC values of -1.408 and -2.892, and P values of 0.443 and 0.054, respectively. The mortality rate increases with age and shows a linear increase after the age of 40. The proportion of pre hospital mortality in acute myocardial infarction ranged from 81.53% to 87.29%, which was at a high level, but showed an overall downward trend (AAPC = -0.552%, P = 0.007). The potential life loss rate ranged from 0.33% to 0.42%, with an average life loss of 6.02 years to 7.03 years, and the trend of change was not statistically significant. However, the potential life loss rate and average life loss of women showed a downward trend, with AAPC values of -5.941% and -3.475%, respectively, and P values of 0.01. Conclusion The mortality rate of acute myocardial infarction in Nanning City is relatively high, and the potential loss of life is severe. Pre hospital emergency treatment and health education for acute myocardial infarction should be strengthened, and the elderly and men are the key population for prevention and con.
