Abstract

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, agestandardized 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.
