Circulating markers of endothelial function in cardiovascular disease

Area of Science:

• Cardiovascular Science
• Biomarker Discovery

Background:

• Endothelial dysfunction is central to cardiovascular disease development.
• Accurate in vivo measurement is vital for primary prevention strategies.
• Existing biomarkers like sICAM-1, sVCAM-1, and sE-selectin have limitations in specificity and application.

Purpose of the Study:

• To evaluate the utility of various biological markers for assessing endothelial dysfunction.
• To identify reliable biomarkers for predicting cardiovascular disease risk and guiding therapeutic intervention.

Main Methods:

• Review and analysis of existing literature on endothelial dysfunction biomarkers.
• Comparison of specificity and predictive value of soluble adhesion molecules, soluble thrombomodulin, and von Willebrand factor.

Main Results:

• Soluble adhesion molecules (sICAM-1, sVCAM-1) lack specificity, being elevated in general inflammation.
• sE-selectin is endothelium-specific but linked to coronary artery disease and diabetes risk.
• Soluble thrombomodulin correlates with disease severity (coronary artery disease, stroke) and decreases with treatment.
• Von Willebrand factor emerges as a superior biomarker, predicting ischemic heart disease and stroke risk.

Conclusions:

• Von Willebrand factor is the most effective endothelial biomarker for predicting cardiovascular events.
• Soluble thrombomodulin shows potential for assessing disease severity and treatment response.
• Accurate endothelial dysfunction markers are essential for early intervention in cardiovascular disease prevention.
