Abstract
Introduction: Cardiovascular disease (CVD) is the leading cause of death and has caused a heavy burden in China. China has about 106 million CVD patients, including 33 million with stroke. This study presents the latest cardiovascular mortality in China in 2019 to provide evidence for disease control and prevention. Methods: Mortality data from the China Death Surveillance Point System (DSP System) was used for CVD mortality estimation. A descriptive analysis was conducted to demonstrate the results. Results: A total of 5.09 million CVD deaths were estimated in China in 2019, with a mortality rate and age-standardized mortality rate of 364.5 per 100,000 population and 276.0 per 100,000, respectively. Stroke is the leading cause of death, and the mortality rate and age-standardized mortality rate (ASMR) were 171.6 per 100,000 and 130.0 per 100,000, respectively. The second major cause was ischemic heart diseases, and the mortality rate and ASMR were 147.3 per 100,000 and 142.1 per 100,000, respectively. Stroke and ischemic heart diseases were the two major causes of CVD deaths, which accounted for over 87% of all CVD deaths. Conclusions: Although age-standardized mortality of CVD continues to decline in China, the number of deaths is still increasing. Therefore, prevention and control efforts for CVD should be maintained. In order to achieve the “Healthy China 2030” goal of reducing the mortality rate of CVD in China, it is necessary to further strengthen the prevention, control, and treatment capacity of stroke. Meanwhile, increases in ischemic heart disease deaths in highly developed areas should be monitored.
Highlights
Cardiovascular disease (CVD) is the leading cause of death and has caused a heavy burden in China
With the acceleration of population aging and urbanization in China, people are increasingly exposed to cardiovascular-related risk factors, and the incidence and prevalence of cardiovascular disease (CVD) has increased in the past 10 years [1]
According to the 2018 report on CVDs in China, the report estimated that the number of cardiovascular patients in China was about 290 million, among which approximately 13 million had stroke and approximately 11 million had coronary heart disease
Summary
Mortality data from the China Death Surveillance Point System (DSP System) was used for CVD mortality estimation. The data analyzed in this study came from the National Disease Surveillance Point (DSP) system of China, which covered 24% of the population (over 300 million) and collected all causes of death in 605 surveillance points. Previous work has demonstrated its national and provincial representativeness [7]. A DSP surveillance point represents a rural county or an urban district, which is an administration unit in China. International Classification of Diseases 10th revision (ICD-10) was used to identify CVD deaths (I00-I99). The mortality data was obtained and stratified by causes of CVD, sex, age group, area type (urban/rural), and region (eastern/ central/western). National population data was obtained from the National Bureau of Statistics in 2019 with identical stratification as the mortality data
