Mortality trend and disease burden of ischemic heart disease in Songjiang district, Shanghai, 2002−2023

Objective To understand the mortality and disease burden of ischemic heart disease (IHD) in Songjiang district of Shanghai.

Methods The death cause surveillance data and demographic data in Songjiang from 2002 to 2023 were collected. The crude mortality rate, standardized mortality rate of IHD, and related years of life lost (YLL), years lived with disability (YLD), disability adjusted life years (DALY) and the average annual percent change (AAPC) were calculated to evaluate the trend of mortality and disease burden of IHD.

Results The crude mortality rate and standardized mortality rate of IHD increased from 18.16/100 000 and 16.02/100 000 in 2002 to 159.50/100 000 and 56.01/100 000 in 2023 in men (AAPC=8.24%, 5.68%, P<0.05) and from 30.86/100 000 and 22.98/100 000 in 2002 to 200.99/100 000 and 63.70/100 000 in 2023 in women (AAPC=7.96%, 5.59%, P<0.05) in Songjiang. The mortality rate was higher in men than in women in age group ＜80 years old. The mortality rate increased in men in age group 50−, 60− and 70− years and decreased in women aged below 50 years. The mortality rate of IHD increased both in men and women aged ≥80 years. The DALY rates in men and women increased from 0.96‰, 1.47‰ to 5.88‰, 5.44‰, respectively (AAPC=7.90%, 6.87%, P<0.05).

Conclusion The mortality rate and disease burden of IHD increased rapidly and showed gender and age specific differences in Songjiang. It is necessary to take targeted measures to prevent IHD.
