Accuracy of numerical coronary profile. Correlation of risk factors with arteriographically documented severity of
Insights
The Framingham coronary risk profile effectively identifies patients with coronary artery disease. Higher risk scores correlate with more severe coronary artery disease, aiding in early detection.
Area of Science:
- Cardiology
- Preventive Medicine
- Medical Risk Assessment
Background:
- The Framingham Risk Score is a widely used tool for estimating cardiovascular disease risk.
- Assessing the correlation between established risk factors and the actual severity of coronary artery disease is crucial for clinical practice.
Purpose of the Study:
- To evaluate the effectiveness of the Framingham coronary risk profile in predicting the severity of coronary artery disease (CAD) diagnosed via coronary angiography.
- To determine if the risk profile can differentiate between patients with and without significant CAD.
Main Methods:
- A cohort of 158 consecutive patients undergoing cardiac catheterization were assessed.
- A coronary risk profile was calculated based on age, sex, smoking, glucose intolerance, left ventricular hypertrophy, blood pressure, and cholesterol levels.
- The calculated risk profile was compared to the severity of CAD determined by coronary angiography.
Main Results:
- Patients with angiographically confirmed CAD had a significantly higher risk profile (1.52) compared to those without CAD (1.08) (P < 0.01).
- The coronary risk profile demonstrated a positive correlation with the severity of coronary artery disease.
- No significant difference in risk profiles was observed between patients with and without a prior myocardial infarction.
Conclusions:
- The Framingham coronary risk profile is a valuable tool for identifying individuals at higher risk for coronary artery disease.
- The presence and severity of coronary artery disease correlate with the number and magnitude of traditional cardiovascular risk factors.
- Easily measurable risk factors can help identify high-risk coronary patients and predict disease extent.
Abstract:
We compared a coronary risk profile (developed by the Framingham Study) based on age, sex, cigarette smoking, glucose intolerance, left ventricular hypertrophy, systolic blood pressure and serum cholesterol to angiographically determined severity of coronary-artery disease in 158 consecutive patients undergoing cardiac catheterization. A profile of 1.0 indicated average relative risk. Risk profiles for 105 patients with angiographically documented coronary-artery disease was 1.52 whereas it was 1.08 for the group without coronary disease (P less than 0.01). There was no difference between the patients with coronary disease with (1.44) and those without previous infarct (1.46). The coronary risk profile, however, increased with increasing severity of coronary disease. The high-risk coronary patient can be identified by seven easily measured risk factors, and the extent of coronary-artery disease increases with the number and severity coronary risk factors.
