Insights
Plasma levels of chemokine CXCL16 are elevated in acute coronary syndrome patients and correlate with coronary artery stenosis severity. CXCL16 shows potential as a biomarker for coronary artery disease (CAD).
Area of Science:
- Cardiovascular Research
- Immunology
- Biomarker Discovery
Background:
- The chemokine CXCL16 is implicated in atherosclerosis and coronary artery disease (CAD).
- The precise role of CXCL16 in atherosclerosis pathogenesis requires further elucidation.
- This study investigates the association between CXCL16 levels and the extent of coronary artery stenosis.
Purpose of the Study:
- To determine the relationship between plasma CXCL16 concentrations and the severity of coronary artery stenosis in patients.
- To evaluate CXCL16 as a potential biomarker for CAD.
Main Methods:
- Plasma CXCL16 levels were measured using ELISA in 16 stable angina pectoris (SAP) patients, 53 acute coronary syndrome (ACS) patients, and 19 controls.
- Patients underwent coronary angiography and were stratified into quartiles based on CXCL16 levels.
- Correlations between CXCL16 levels, clinical characteristics, and Gensini scores were analyzed.
Main Results:
- CXCL16 levels were significantly higher in ACS patients compared to controls and SAP patients (p <0.01 and p <0.05, respectively).
- Gensini scores progressively increased across CXCL16 quartiles, with the highest quartile showing significantly greater stenosis than the lowest (p <0.001).
- CXCL16 levels demonstrated a significant positive correlation with Gensini scores (r = 0.519, p <0.001).
Conclusions:
- Plasma CXCL16 levels are positively associated with the severity of coronary artery stenosis.
- CXCL16 activity in human plasma may serve as a valuable biomarker for epidemiological and clinical applications in CAD.
Background:
The novel chemokine CXCL16 is involved in the development of atherosclerosis and coronary artery disease (CAD). However, the role of CXCL16 in atherosclerosis remains uncertain. This study was designed to investigate the relationship between CXCL16 and the severity of coronary artery stenosis.
Methods:
Using ELISA, we assayed the plasma CXCL16 concentration in 16 stable angina pectoris (SAP) patients, 53 acute coronary syndrome (ACS) patients, and 19 control patients. All patients underwent coronary angiography after admission. They were divided into four groups according to the quartile of CXCL16 level. Characteristics and the relationship between CXCL16 and the elements were studied in each group.
Results:
CXCL16 levels in the ACS group were higher than controls and SAP group (p <0.01 vs. controls; p <0.05 vs. SAP group). Gensini score in the highest quartile group of CXCL16 level (group IV, CXCL16 >2.21 ng/mL) was significantly higher than in the lowest quartile group of CXCL16 level (group I, CXCL16 < or = 1.43 ng/mL) (p <0.001). Gensini score in group II (1.43 ng/mL
Conclusions:
CXCL16 levels are positively associated with the severity of coronary artery stenosis. Activity level of CXCL16 in human plasma appears to be a good biomarker for epidemiological and clinical application in CAD.
