Key result
Myocarditis burden in China declined by ~2% annually between 1992 and 2021.
Why the study?
Myocarditis can lead to severe complications, and the number of cases and deaths in China has shown an upward trend, causing a substantial disease burden.
Observational
While the overall burden of myocarditis in China is decreasing, mortality and DALYs remain higher than the global average, highlighting the need for targeted prevention in males and extremes of age.

May inform targeted myocarditis surveillance in Chinese males and age extremes; leaves open drivers of excess mortality versus global averages.
What is already known about this topic?: Myocarditis is a prevalent cardiovascular condition that can lead to severe complications. The number of patients with myocarditis, new cases, and deaths in China has been on an upward trend over the years, causing a certain disease burden. What is added by this report?: The overall burden of myocarditis in China is on a downward trend; however, the age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life years (DALYs) rate remain higher than the global average. The age-standardized incidence rate (ASIR), ASMR and age-standardized DALYs rate were higher in men than in women. Individuals younger than 5 years or older than 70 years, the period from 2002-2016, and birth cohort earlier than 1957 were identified as risk factors for myocarditis-related mortality. What are the implications for public health practices?: We should still prioritize the prevention and treatment of myocarditis. It is recommended that primary and secondary prevention efforts focus on individuals younger than 5 years, older than 70 years, and males, with an emphasis on proactive health education and management.

Wang et al. (2025) conducted an observational in Myocarditis. Time period (1992 to 2021) vs. 1992 baseline was evaluated on Age-standardized DALYs rate (AAPC -1.958, 95% CI -2.219 to -1.696, p=<0.001). Between 1992 and 2021, the overall burden of myocarditis in China decreased, with the age-standardized DALYs rate declining by an average annual percent change of -1.958.
