Insights
Cardiovascular disease (CVD) mortality in Korea significantly declined from 1983-2018. However, rising heart disease deaths, particularly heart failure, require focused prevention and management strategies.
Area of Science:
- Cardiovascular epidemiology
- Public health research
- Mortality statistics analysis
Background:
- Cardiovascular disease (CVD) mortality trends are crucial for public health strategies.
- Analysis of Korean Cause of Death Statistics from 1983 to 2018.
Purpose of the Study:
- To examine temporal trends in CVD mortality in Korea.
- To inform strategies for reducing the burden of cardiovascular disease.
Main Methods:
- Utilized International Classification of Disease, 10th revision for cause of death coding.
- Analyzed mortality data for circulatory system diseases and specific subcategories (heart diseases, cerebrovascular diseases).
- Calculated crude, age-standardized, and age-stratified rates to assess trends.
Main Results:
- Overall age-standardized CVD mortality rates significantly decreased between 1983 and 2018.
- Cerebrovascular disease mortality showed a consistent decreasing trend.
- Heart failure mortality rates rapidly increased in recent years, contrasting with overall declines.
Conclusions:
- Despite a significant long-term decrease in CVD mortality, recent increases in heart disease deaths, especially heart failure, are a concern.
- Targeted prevention and management strategies are needed for heart failure and other cardiovascular conditions.
- Continued monitoring of CVD mortality trends is essential for public health planning.
Background And Objectives:
Understanding the trends in cardiovascular disease (CVD) mortality is important for developing burden reduction strategies. Based on the Cause of Death Statistics, we examined the changing patterns of CVD mortality in Korea between 1983 and 2018.
Methods:
Causes of death were coded according to the International Classification of Disease, 10th revision. Deaths from all diseases of circulatory system (I00-I99) and the following 6 subcategories were analyzed: total heart diseases (I00-I13 and I20-I51), hypertensive heart diseases (I10-I13), ischemic heart diseases (I20-I25), myocardial infarction (I21-I23), heart failure (I50), and cerebrovascular diseases (I60-I69). Crude, age-standardized, and age-stratified rates were calculated to assess temporal trends in CVD mortality.
Results:
The number of deaths and crude mortality rate for all diseases of circulatory system increased recently mainly due to the population ageing. Specifically, total heart diseases showed increasing trend, whereas cerebrovascular diseases showed decreasing trend. Between 1983 and 2018, age-standardized mortality rates significantly declined for all diseases of circulatory system, total heart diseases, hypertensive heart diseases, and cerebrovascular diseases. Age-standardized mortality rates for ischemic heart diseases and myocardial infarction peaked in the early 2000s then decreased thereafter. However, age-standardized mortality rate for heart failure rapidly increased, especially in recent years.
Conclusions:
CVD mortality in Korea has remarkably decreased over the last 36 years. However, the recent rise in the absolute number of deaths from heart diseases, especially from heart failure, calls for attention in prevention and management of CVD and its sequelae.
