Changing profiles of cardiovascular disease and risk factors in China: a secondary analysis for the Global Burden of Disease Study 2019

BACKGROUND: Understanding the changing profiles of cardiovascular disease (CVD) and modifiable risk factors is essential for CVD prevention and control. We aimed to report the comprehensive trends in CVD and risk factors in China from 1990 to 2019. METHODS: Data on the incidence, death, and disability-adjusted life years (DALYs) of total CVD and its 11 subtypes for China were obtained from the Global Burden of Disease Study 2019. The CVD burden attributable to 12 risk factors was also retrieved. A secondary analysis was conducted to summarize the leading causes of CVD burden and attributable risk factors. RESULTS: From 1990 to 2019, the number of CVD incidence, death, and DALYs considerably increased by 132.8%, 89.1%, and 52.6%, respectively. Stroke, ischemic heart disease, and hypertensive heart disease accounted for over 95.0% of CVD deaths in 2019 and remained the top three causes during the past 30 years. Between 1990 and 2019, the age-standardized rate of stroke decreased significantly (percentage of decreased incidence: -9.3%; death: -39.8%; DALYs: -41.6%), while the rate of ischemic heart disease increased (percentage of increased incidence: 11.5%; death: 17.6%; DALYs: 2.2%). High systolic blood pressure, unhealthy diet, tobacco, and air pollution continued to be the major contributors to CVD deaths and DALYs (attributing to over 70% of the CVD burden), and the high body mass index (BMI)-associated CVD burden had the largest increase between 1990 and 2019. CONCLUSIONS: The significant increases in the number of CVD incident cases, deaths, and DALYs suggest that the CVD burden is still a concern. Intensified strategies and policies are needed to maintain promising progress in stroke and to reduce the escalating burden of ischemic heart disease. The CVD burden attributable to risk factors has not yet made adequate achievements; even worse, high BMI has contributed to the increasing CVD burden.
