Endothelial Function in Patients With Von Willebrand Disease

Area of Science:

• Cardiovascular Medicine
• Hematology
• Vascular Biology

Background:

• Increased life expectancy in von Willebrand disease (vWD) patients necessitates understanding age-related comorbidities.
• Endothelial function is crucial for vascular health and may be affected in chronic conditions.

Purpose of the Study:

• To investigate whether patients with von Willebrand disease exhibit altered endothelial function compared to the general population.
• To compare endothelial dysfunction markers and reactive hyperemia index (RHI) between vWD patients, healthy controls, and coronary artery disease (CAD) patients.

Main Methods:

• Inclusion of 37 vWD patients (types 1, 2, 3), 14 controls, and 38 CAD patients.
• Determination of five markers of endothelial dysfunction (MOED).
• Assessment of endothelial function using Itamar Endo-PAT to calculate the reactive hyperemia index (RHI).

Main Results:

• Higher levels of soluble intercellular adhesion molecule-1, P-Selectin, interleukin-6, and monocyte chemoattractant protein-1 were observed in vWD patients but were not statistically significant compared to controls.
• Reactive hyperemia index (RHI) was impaired in CAD patients (1.855) but not significantly different between vWD patients (1.870) and controls (2.112).

Conclusions:

• Endothelial function in patients with von Willebrand disease is not significantly different from that of healthy controls.
• Further research may be needed to explore subtle endothelial changes or long-term vascular implications in vWD.
