Aortic stiffness in patients with wilson's disease

Area of Science:

• Cardiovascular Physiology
• Metabolic Disorders
• Vascular Medicine

Background:

• Wilson disease (WD) is a genetic disorder of copper metabolism with diverse clinical manifestations.
• While neurological and hepatic involvement are common, cardiac and vascular aspects of WD are less understood.
• Existing research suggests a link between copper levels and atherosclerosis, yet aortic stiffness in WD remains uninvestigated.

Purpose of the Study:

• To evaluate and compare aortic stiffness in patients diagnosed with Wilson disease (WD).
• To investigate potential associations between WD and markers of arterial stiffness.

Main Methods:

• Aortic stiffness was assessed in 32 WD patients and 24 healthy controls using the SphygmoCor device.
• Key parameters measured included aortic pulse wave velocity (PWV), augmentation pressure (AP), and augmentation index (AIx).
• Central aortic pressures (systolic, diastolic, mean, pulse) were also recorded.

Main Results:

• Demographic and clinical characteristics (age, sex, BMI, renal/hepatic function) were comparable between WD patients and controls.
• Patients with WD exhibited anemia and thrombocytopenia, but echocardiographic findings were similar to controls.
• No significant differences were observed in central aortic pressures, AP, AIx, or PWV between the WD group and healthy controls.

Conclusions:

• Aortic stiffness, as measured by PWV, AP, and AIx, does not appear to be significantly altered in patients with Wilson disease.
• The findings suggest that Wilson disease, in the absence of other cardiovascular risk factors, may not directly impact aortic stiffness.
