Insights
Traditional cardiovascular risk factors alone are insufficient for predicting future events. Incorporating additional factors and detecting subclinical atherosclerosis can improve cardiovascular risk assessment.
Area of Science:
- Cardiology
- Preventive Medicine
- Medical Diagnostics
Background:
- Traditional cardiovascular risk factors are established causes of atherosclerosis but have limited predictive power for future clinical events.
- Current risk scores (e.g., Framingham) have limitations in geographic applicability and discrimination, especially in intermediate-risk categories.
- Individuals often present with multiple moderate risk factors, necessitating global risk assessment.
Purpose of the Study:
- To evaluate the limitations of traditional cardiovascular risk factors and existing risk scores.
- To highlight the need for improved cardiovascular risk stratification methods.
- To emphasize the role of complementary risk factors and subclinical atherosclerosis detection.
Main Methods:
- Review of existing literature on cardiovascular risk factors and risk prediction models.
- Analysis of the limitations of traditional risk assessment tools.
- Discussion of the utility of complementary risk factors and subclinical atherosclerosis detection.
Main Results:
- Traditional risk factors alone do not adequately predict future cardiovascular events.
- Existing risk scores demonstrate limitations in accuracy and applicability across diverse populations.
- Subclinical atherosclerosis detection offers a complementary approach to reclassifying cardiovascular risk.
Conclusions:
- Improved cardiovascular risk assessment requires moving beyond traditional factors.
- Integrating complementary risk factors and diagnostic tools like subclinical atherosclerosis detection is crucial.
- Enhanced risk stratification can lead to more personalized and effective preventive strategies.
Abstract:
Although traditional cardiovascular risk factors play a proven aetiologic role in atherosclerosis-related cardiovascular disease, they fail to predict the occurrence of future clinical events, and, taken separately, they provide useful therapeutic target rather than diagnostic tools. Apart from the situation of severe monorisk, more frequent is the presentation of one individual with numerous moderate risk factors, the resulting global risk of whom being estimated by risk scores, such as the Framingham risk score or its derivatives. These models suffer various limitations, including the lack of applicability depending on geographic zones, and the lack of discrimination in the intermediate risk category, as compared to a better predictive value in the low risk and high risk categories. This lack is partially overcome by models that include complementary risk factors, requiring the need for other tools of reclassification, including the detection of subclinical atherosclerosis.
