Clinical Report: Association of Serum ANGPTL4 Levels with Severe Coronary Artery Calcification
Overview
This study identifies a significant association between serum ANGPTL4 levels and severe coronary artery calcification (CAC). A nomogram was developed to predict the risk of severe CAC, demonstrating acceptable discriminatory ability.
Background
Coronary artery calcification is a critical indicator of atherosclerosis and is linked to increased cardiovascular event risk. Identifying biomarkers like ANGPTL4 could enhance early detection and management strategies for patients at risk of severe CAC. Understanding the role of ANGPTL4 in lipid metabolism and its potential as a treatment target is essential for improving cardiovascular health outcomes.

Key Findings
Serum ANGPTL4 levels are significantly higher in patients with severe CAC compared to those with non-severe CAC (p = 0.007).
ANGPTL4 levels are positively associated with CAC severity, independent of other clinical risk factors.
The predictive model for severe CAC includes age, smoking status, statin use, HbA1c, serum phosphate, and ANGPTL4.
The nomogram developed shows an AUC of 0.708, indicating acceptable discriminatory ability for severe CAC.
Identifying ANGPTL4 as a potential biomarker may aid in the early prediction and management of vascular calcification.
Clinical Implications
Clinicians should consider measuring serum ANGPTL4 levels as part of the risk assessment for patients with suspected severe coronary artery calcification. The developed nomogram may assist in stratifying patients for preventive interventions and tailoring treatment strategies based on individual risk profiles.
Conclusion
The findings suggest that ANGPTL4 is a promising biomarker for severe coronary artery calcification, which could enhance risk prediction and inform treatment approaches in cardiovascular care.
