Insights
Biomarkers angiopoietin-like 4 (ANGPTL-4) and galectin-3 were evaluated for assessing coronary artery disease (CAD) severity. Results indicate these biomarkers do not reliably reflect CAD severity, suggesting further research is needed for their role in CAD management.
Area of Science:
- Cardiology
- Biomarker Research
- Clinical Chemistry
Background:
- Coronary artery disease (CAD) is a major global health concern.
- Investigating novel biomarkers is crucial for understanding and managing CAD.
- ANGPTL-4 and galectin-3 are potential biomarkers for cardiovascular conditions.
Purpose of the Study:
- To determine if angiopoietin-like 4 (ANGPTL-4) and galectin-3 levels correlate with the severity of coronary artery disease (CAD).
- To assess the utility of ANGPTL-4 and galectin-3 as diagnostic or prognostic indicators in patients with varying degrees of CAD.
Main Methods:
- Serum levels of ANGPTL-4 and galectin-3 were measured in 226 patients with different CAD classifications and normal controls using ELISA.
- Correlations were analyzed between biomarker levels and established CAD severity scores (GRACE and GENSINI) using Spearman's rank correlation and multivariate analysis.
Main Results:
- Both ANGPTL-4 and galectin-3 were found to be significantly elevated in CAD patients compared to controls.
- While some correlations were observed between ANGPTL-4/galectin-3 and CAD severity scores in specific patient subgroups, these relationships were not consistently significant.
- Multivariate analysis did not sustain a significant correlation between ANGPTL-4 or galectin-3 and overall CAD severity.
Conclusions:
- ANGPTL-4 and galectin-3 do not appear to be reliable biomarkers for assessing the severity of coronary artery disease.
- Further research is warranted to explore the potential role of these biomarkers in the broader management strategies for CAD.
- The findings suggest current evidence does not support routine clinical use of ANGPTL-4 and galectin-3 for CAD severity assessment.
Background:
Coronary artery disease (CAD) is one of the leading causes of mortality and morbidity worldwide. We thereby sought to investigate whether the biomarkers, angiopoietin-like 4 (ANGPTL-4) and galectin-3, reflect the severity of CAD.
Methods:
Patients were screened based on inclusion/exclusion criteria and written informed consent was obtained from the patients. Serum ANGPTL-4 and galectin-3 was quantified using enzyme-linked immunosorbent assay (ELISA) and correlated with the Global Registry of Acute Coronary Events (GRACE) and GENSINI score using Spearman's rank correlation coefficient and multivariate analysis.
Results:
A total of 226 patients consisting of ST-segment elevation myocardial infarction (STEMI), non-STEMI/unstable angina (USA), chronic stable angina (CSA) and normal controls (NCs) participated in the study. ANGPTL-4 and galectin-3 were significantly higher in CAD than the NC group. ANGPTL-4 showed significant negative correlation with GRACE score in acute coronary syndrome (ACS) ( r = -0.211, p = 0.03) patients. ANGPTL-4 showed significant positive correlation with serum creatinine ( r = 0.304, p = 0.056) and body mass index (BMI) ( r = 0.424, p = 0.009) in CSA patients. A modest positive correlation was observed between the serum galectin-3 levels and GRACE score ( r = 0.187, p = 0.055) in ACS patients. However, on multivariate analysis the positive correlation relationship between ANGPTL-4 and galectin-3 with the severity of CAD was not sustained.
Conclusion:
In conclusion, ANGPTL-4 and galectin-3 do not appear to have a promising role for assessing the severity of CAD. Nevertheless these biomarkers do warrant further exploration in improving the management of CAD.
