Insights
C-reactive protein (CRP) measurement offers no additional benefit for predicting cardiovascular events when traditional risk factors are known. This study found CRP did not improve risk prediction models in the Iranian population.
Area of Science:
- Cardiology
- Biomarkers
- Public Health
Background:
- Cardiovascular disease (CVD) remains a leading cause of mortality globally.
- Accurate risk prediction is crucial for effective CVD prevention strategies.
- Inflammatory markers, such as C-reactive protein (CRP), are being investigated for their role in CVD risk assessment.
Purpose of the Study:
- To determine the added value of high-sensitivity C-reactive protein (hs-CRP) in predicting cardiovascular outcomes.
- To compare the predictive utility of hs-CRP against established cardiovascular risk factors.
- To assess hs-CRP's contribution to risk prediction models in an Iranian population.
Main Methods:
- A nested case-control study was conducted within the Tehran Lipid and Glucose Study (TLGS).
- 207 cardiovascular events were analyzed over 3 years, with cases matched to controls by age and sex.
- hs-CRP and traditional cardiovascular risk factors were measured at baseline.
Main Results:
- hs-CRP showed modest correlations with body mass index, waist-to-hip ratio, total cholesterol, and the Framingham coronary risk score.
- Elevated hs-CRP levels were initially associated with a higher risk of cardiovascular events (RR=2.6).
- However, this association became non-significant after adjusting for traditional risk factors, and hs-CRP did not improve risk prediction models.
Conclusions:
- In the Iranian population, hs-CRP measurement provides no additional predictive value for short-term cardiovascular outcomes when traditional risk factors are already known.
- Current traditional risk factors are sufficient for risk stratification in this population.
- Further research may explore CRP's role in different populations or for different timeframes.
Background:
The main aim of this study was to evaluate the additional utility of C-reactive protein (CRP) over traditional cardiovascular risk factors in risk prediction of cardiovascular outcomes.
Methods:
In a nested case-control study, 207 cardiovascular events among participants over 30 years of the Tehran Lipid and Glucose Study (TLGS) were documented during 3 years of follow-up. Those cases that were free of cardiovascular disease at baseline (126 subjects) were matched to 259 controls for age and sex. High sensitivity CRP and traditional cardiovascular risk factors were measured at baseline.
Results:
Modest correlation was found between CRP and body mass index (r=0.34), waist-to-hip ratio (r=0.22), total cholesterol (r=0.24) and calculated 10-year Framingham coronary risk score (FRS) (r=0.27) (all P values <0.001). The age and sex adjusted relative risk of cardiovascular events for subjects in the highest quartile of the population distribution of CRP compared with the lowest quartile was 2.6 (95% CI=1.4-5.1, P=0.006). After additional adjustment for traditional cardiovascular risk factors the odds ratio decreased to non-significant levels (0.8, 95% CI=0.3-1.9). Addition of CRP did not improve the area under receiver operating characteristic curve of risk functions that was based on traditional cardiovascular risk factors or FRS.
Conclusion:
It seems that for short-term prediction of cardiovascular disease outcomes in the Iranian population, measurement of CRP has no additional value when traditional cardiovascular risk factors are known.
