[Analysis of the trend changes in the burden of cardiovascular disease mortality in China from 2010 to 2021]

Objective: To analyze the current status and trend of the mortality burden of cardiovascular disease in China from 2010 to 2021. Methods: Data related to cardiovascular disease mortality and disability-adjusted life year (DALY) were extracted from the Global Burden of Disease Study 2021 (GBD2021) database. The age-standardized mortality rate and DALY rate were calculated, using the 2021 world standard population estimated by GBD2021. Joinpoint 5.2.0 software was used to calculate the mortality rate, standardized mortality rate, DALY rate, standardized DALY rate, annual percent change (APC), average annual percent change (AAPC), and 95%CI of cardiovascular disease in China from 2010 to 2021. Results: The mortality rate of cardiovascular disease was 357.44/100 000, and the age-standardized mortality rate was 280.11/100 000 in China in 2021. The DALY rate was 7 043.33/100 000, and the age-standardized DALY rate was 5 120.06/100 000. From 2010 to 2021, the mortality rate and DALY rate of cardiovascular disease in China showed an upward trend (AAPC was 1.58% and 0.83%, respectively, both P<0.05), and the standardized mortality rate and standardized DALY rate showed a downward trend (AAPC was -2.13% and -2.02%, respectively, both P<0.05). The mortality burden of cardiovascular disease was higher in males (mortality rate 392.80/100 000, DALY rate 8 156.19/100 000) than in females (mortality rate 320.38/100 000, DALY rate 5 876.87/100 000). With the increase older in age, the mortality burden of cardiovascular disease in China decreased first and then increased. China ranked high in the mortality burden of cardiovascular disease among G20 member countries. Conclusions: The death burden of cardiovascular disease is serious in China. The mortality rate and DALY rate of cardiovascular disease in China showed an increasing trend from 2010 to 2021, and the standardized mortality rate and standardized DALY rate of cardiovascular disease ranked high in G20 member countries. The death burden of cardiovascular disease was more serious in men and the elderly. It is necessary to develop more comprehensive prevention, treatment, and rehabilitation measures for men and the elderly to reduce mortality and disability rates, decrease the disease burden, and improve the quality of life.
