A Comparative Study of Carotid Ultrasound Findings in Patients With and Without Familial Hypercholesterolemia

Area of Science:

• Cardiovascular Medicine
• Genetics
• Diagnostic Imaging

Background:

• Familial hypercholesterolemia (FH) is a genetic disorder increasing early coronary and heart valve disease risk.
• Atherosclerosis evaluation using carotid ultrasound is a key diagnostic tool.
• Understanding FH-specific atherosclerosis characteristics is vital for risk stratification.

Purpose of the Study:

• To compare carotid ultrasound findings between FH and non-FH patients.
• To identify unique atherosclerosis characteristics in FH patients.
• To assess the impact of age on atherosclerosis markers in FH.

Main Methods:

• Carotid ultrasound examinations were performed on FH and non-FH patients at a dyslipidemia clinic.
• Clinical data and laboratory values were collected at the initial ultrasound.
• Carotid ultrasound findings, including plaque score (PS) and intima-media thickness (IMT), were compared between matched groups.

Main Results:

• FH patients demonstrated significantly higher PS and IMT than non-FH patients.
• In patients aged 50 and over, FH was associated with significantly higher PS and IMT.
• No significant differences in PS or IMT changes over time were observed between FH and non-FH groups.

Conclusions:

• Carotid ultrasound reveals distinct atherosclerosis patterns in FH patients, particularly those over 50.
• The findings underscore the importance of early FH diagnosis.
• Adequate FH management, including timely treatment, is essential for mitigating cardiovascular complications.
