Summary
6 papers analyzed
These studies suggest that cardiovascular disease (CVD) and congenital heart disease (CHD) are interconnected, with CHD increasing the risk of CVD, and that preventive measures like a DASH-like diet can significantly reduce the risk of both.

Cardiovascular Disease (CVD) vs. Coronary Heart Disease (CHD): A Comparative Analysis
Introduction to Cardiovascular Disease (CVD) and Coronary Heart Disease (CHD)
Cardiovascular disease (CVD) encompasses a broad range of heart and blood vessel disorders, including coronary heart disease (CHD), stroke, hypertension, and heart failure. CHD, a subset of CVD, specifically refers to conditions that affect the coronary arteries, which supply blood to the heart muscle. Understanding the distinctions and overlaps between CVD and CHD is crucial for effective prevention, management, and policy-making.
Economic Burden of CVD and CHD in Low- and Middle-Income Countries
The economic impact of CVD and CHD is significant, particularly in low- and middle-income countries (LMICs). Studies indicate that the costs associated with CVD, including hypertension, are relatively homogeneous, ranging from $500 to $1500 per episode. However, the costs for CHD and stroke are notably higher and more variable, often exceeding $5000 per episode. This disparity highlights the need for targeted economic research and improved methodological quality to better inform policy priorities in these regions.
Risk Assessment and Primary Prevention
Accurate risk assessment is vital for the primary prevention of both CVD and CHD. The Framingham risk scores, widely used for predicting 10-year risk, show considerable variability in performance across different populations. For CHD, the predicted to observed risk ratios range from an underprediction of 0.43 in high-risk populations to an overprediction of 2.87 in lower-risk populations. Despite the widespread use of these risk scores, evidence supporting their effectiveness in improving clinical outcomes remains limited.
Long-term Cardiovascular Risks for CHD Survivors
Survivors of congenital heart disease (CHD) face increased long-term risks of developing other cardiovascular conditions. Meta-analyses reveal that individuals with CHD have significantly higher relative risks for CVD (3.12), stroke (2.46), heart failure (5.89), and coronary artery disease (1.50) compared to controls. These findings underscore the importance of continuous cardiovascular monitoring and management for CHD survivors to mitigate these elevated risks.
Epidemiological Insights and Preventive Strategies
Epidemiological studies have been instrumental in identifying risk factors and developing preventive strategies for CHD. Key risk factors include hypertension, smoking, diabetes, elevated cholesterol, and obesity. Effective prevention of CHD involves managing these risk factors through both population-level and individual-level interventions, supported by short-term and long-term risk prediction algorithms. These strategies are essential for reducing the global burden of CHD and improving cardiovascular health outcomes.
Dietary Interventions and CVD/CHD Risk Reduction
Dietary interventions, such as the Dietary Approaches to Stop Hypertension (DASH) diet, have shown significant protective effects against CVD and CHD. Meta-analyses indicate that adherence to a DASH-style diet can reduce the risk of CVD by 20%, CHD by 21%, stroke by 19%, and heart failure by 29%. These findings highlight the potential of dietary modifications as a non-pharmacological approach to reducing cardiovascular risk.
Conclusion
In summary, while CVD and CHD are closely related, they present distinct challenges and require tailored approaches for effective management and prevention. The economic burden of these diseases is substantial, particularly in LMICs, necessitating more robust and high-quality research. Accurate risk assessment tools and preventive strategies, including dietary interventions, are crucial for mitigating the long-term risks associated with these conditions. Continuous efforts in research, policy-making, and clinical practice are essential to address the global impact of CVD and CHD.
