Cardiovascular disease risk reduction for all-cause mortality benefit in low-risk individuals

Background: Current recommendations for the primary prevention of cardiovascular disease (CVD) are based solely on 10-year CVD risk assessment. However, CVD mortality is not compared with all-cause mortality, which could provide insights into the potential benefits of CVD risk interventions on overall mortality. Methods: CVD risk for average American white and black males and females is calculated using the 2013 American Heart Association equations. CVD death risk is determined by combining CVD risk with the death rate following a CVD diagnosis. This CVD death risk is then compared with all-cause mortality data from National Vital Statistics Reports. A larger ratio indicates that most deaths are attributed to CVD, suggesting that intervention may be more beneficial. Results: The CVD mortality ratio is highest for white men and lowest for black men, indicating that white male likely to benefit most from CVD risk modification, while black males will benefit the least. Additionally, the ratio, and the potential benefit, decreases with age for all groups, especially after the age of 70. Conclusion: For the average U.S. population without a CVD diagnosis, the potential mortality benefit from interventions targeting CVD risk factors varies significantly based on patient characteristics such as race, age, and gender. The potential benefit is greatest for white males and decreases with age for all groups.
