Insights
Elevated serum fibrinogen levels correlate with increased coronary artery disease (CAD) severity. This finding highlights fibrinogen as a potential biomarker for assessing CAD progression, especially in men and diabetic patients.
Area of Science:
- Cardiovascular Medicine
- Clinical Chemistry
- Biomarker Research
Context:
- Coronary artery disease (CAD) poses a significant global health burden.
- Assessing the severity of coronary artery stenosis is crucial for patient management.
- Identifying reliable biomarkers for CAD severity is an ongoing area of research.
Purpose:
- To investigate the association between serum fibrinogen levels and the severity of coronary artery stenosis in patients with suspected CAD.
- To determine if fibrinogen serves as an independent predictor of CAD severity.
Summary:
- A study of 195 patients with suspected CAD utilized coronary angiography and a modified Gensini score to quantify stenosis severity.
- Serum fibrinogen levels were analyzed in relation to CAD severity, controlling for other risk factors.
- Results showed a significant positive correlation between fibrinogen and CAD severity, with elevated levels particularly associated with severe disease in men and diabetic individuals.
Impact:
- This research identifies serum fibrinogen as a potential independent biomarker for coronary artery disease severity.
- Findings may inform clinical risk stratification and treatment strategies for CAD patients.
- Further research could explore the mechanistic link between fibrinogen and atherosclerotic plaque progression.
Objective:
To study the relationship between serum advanced fibrinogen and the severity of coronary artery stenosis.
Methods:
In a collection of 195 patients suspected of coronary artery disease (CAD), coronary artery stenosis was studied with coronary angiography. The severity of coronary artery disease was quantified with a modified Gensini score on the basis of angiographic imaging manipulation system. Fibrinogen, total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and D-dimer were determined in all the patients. After the influences of other risk factors were controlled, the relationship between fibrinogen and severity of CAD was analyzed.
Results:
Partial correlation analysis showed that fibrinogen was positively correlated with the severity of CAD (r = 0.293, P < 0.01). Multiple stepwise regression analysis indicated that fibrinogen and age were significant variables associated with the severity of coronary artery disease (F value was 16.89, 15.47, P < 0.01; R was 0.29, 0.38, P < 0.01). All the patients were assigned to one of four groups according to fibrinogen level with 25, 50 and 75 percentile as cut-off points. We found that high fibrinogen level was associated with severe coronary artery disease, particularly in men and in diabetes mellitus patients.
Conclusion:
Elevated fibrinogen level is related to the severity of CAD.
