Trends in Heart Disease Deaths in Kazakhstan: Improvements and Challenges

What is it about?

The study analyzed the trend of avoidable mortality from cardiovascular diseases (CVD) in Kazakhstan from 2011 to 2021. The methodology involved extracting data on population by age and mortality rates from specific CVD categories, such as chronic rheumatic heart disease, hypertensive diseases, ischemic heart disease, and cerebrovascular diseases, using records from the Bureau of National Statistics of Kazakhstan. Join point regression was applied to calculate the average annual percentage change (AAPC) in mortality rates, and crude mortality trends were determined per 100,000 population. The study found a decrease in avoidable mortality rates, including both treatable and preventable mortality, from 2011 to 2019, followed by an increase in 2020 and 2021. The AAPC indicated a significant overall decline in avoidable mortality rates, with stronger reductions observed in males compared to females. Despite the overall decline, mortality rates among young people remained high. The findings suggest that recent efforts in healthcare reforms and early diagnosis contribute to the observed trends in mortality reduction.

Why is it important?

This study is important as it provides critical insights into the trends of avoidable mortality from cardiovascular diseases (CVD) in Kazakhstan, focusing on the impact of healthcare reforms over the past decade. By analyzing avoidable mortality, which includes both preventable and treatable deaths, the research evaluates the effectiveness of national health policies aimed at reducing premature mortality. The findings highlight the significance of strengthening primary healthcare, promoting early diagnosis, and managing risk factors, offering valuable guidance for future health interventions. This study not only contributes to the understanding of CVD trends in Kazakhstan but also underscores the importance of comprehensive healthcare strategies in combating leading causes of mortality globally. Key Takeaways: 1. Reduction in Mortality Rates: The study finds that avoidable mortality rates from CVD in Kazakhstan decreased overall from 2011 to 2021, with a notable decline in treatable and preventable mortality until 2019, followed by a slight increase in 2020 and 2021. 2. Gender-Specific Trends: The research reveals that avoidable mortality rates from ischemic heart disease, cerebrovascular, and hypertensive diseases have reduced more significantly in males compared to females, indicating the need for targeted interventions. 3. Persistent Challenges for Youth: Despite the overall decline in crude mortality rates, the study highlights that mortality among young people remains high, suggesting a continued need for effective health literacy programs and preventive measures to address CVD risk factors in this demographic.
