Insights
The Systematic Coronary Risk Evaluation (SCORE) score better predicts coronary artery disease (CAD) severity in high-risk individuals compared to Framingham and PROCAM scores. This finding aids in managing CAD risk more effectively.
Area of Science:
- Cardiology
- Medical Risk Assessment
Background:
- Accurate prediction of coronary artery disease (CAD) severity is crucial for effective patient management.
- Existing risk scores like Framingham, PROCAM, and SCORE are used to identify high-risk individuals.
- The SYNTAX score, derived from coronary angiography, quantifies CAD severity.
Purpose of the Study:
- To evaluate the relationship between the SYNTAX score and established coronary risk scores (Framingham, PROCAM, SCORE).
- To determine the utility of these risk scores in predicting CAD severity.
Main Methods:
- 205 patients with diagnosed stable angina pectoris and documented CAD were analyzed.
- Coronary angiography was performed to determine SYNTAX scores.
- Coronary risk scores (Framingham, PROCAM, SCORE) were calculated for all patients.
- Statistical analysis was conducted to assess the correlation between SYNTAX scores and the risk scores.
Main Results:
- A positive correlation was observed between the SYNTAX score and the coronary risk scores.
- Framingham and SCORE risk scores demonstrated superior predictive value for the SYNTAX score compared to PROCAM.
- Specifically, Framingham and SCORE showed statistically significant predictive capabilities (p = 0.029, 0.033, and 0.002).
Conclusions:
- The SCORE risk score exhibited a significantly higher predictive value for identifying high-risk patients with severe CAD (p = 0.005).
- These findings suggest that SCORE may be more effective in stratifying CAD severity among high-risk populations.
Background:
Reliable risk scoring systems that can predict the severity of coronary artery disease (CAD) are necessary to implement effective management strategies in high-risk patients. Atherosclerotic vascular disease and with cardiovascular morbidity and mortality risk are patients who would benefit most from a change in patients at high risk factors. Framingham Risk Score, the Prospective Cardiovascular Münster (PROCAM) score and Systematic Coronary Risk Evaluation (SCORE) risk scores are used for this purpose. The severity of the CAD as detected by coronary angiography can be estimated using the SYNTAX score. In this study, it is aimed to assess the relation between SYNTAX score and the Framingham, PROCAM and SCORE scores in the context of their utility for the determination of the severity of the CAD.
Methods:
A total of 205 patients with documented CAD who underwent coronary angiography due to a diagnosis of stable angina pectoris were included in this study. Coronary risk scores were determined for each patient. The relation between the SYNTAX score and the results of coronary risk scoring systems were analyzed.
Results:
A positive relationship between the SYNTAX score, which reflects the severity of the CAD and coronary risk scores was found. However, Framingham and SCORE were superior, i.e., had more predictive value, regarding their ability to predict the SYNTAX score (p = 0.029, 0.033 and 0.002, respectively).
Conclusions:
Examination of the distribution of SYNTAX score across low, intermediate and high-risk groups showed a significantly higher predictive value of SCORE for high-risk patients (p = 0.005).
