Carotid Plaques Correlates in Patients With Familial Hypercholesterolemia

Area of Science:

• Cardiovascular Medicine
• Lipid Metabolism
• Atherosclerosis Research

Background:

• Familial hypercholesterolemia (FH) significantly elevates the risk of premature cardiovascular disease.
• Subclinical atherosclerosis, indicated by carotid plaques and carotid intima-media thickness (cIMT), is a key concern in FH patients.

Purpose of the Study:

• To investigate factors associated with carotid plaques and cIMT in patients with FH.
• To identify specific lipid profiles and clinical parameters linked to subclinical atherosclerosis in this high-risk population.

Main Methods:

• Cross-sectional study of 241 patients diagnosed with familial hypercholesterolemia.
• Assessment of carotid plaques and cIMT using ultrasound imaging.
• Statistical analysis including logistic regression and correlation to identify associated factors.

Main Results:

• Patients with carotid plaques exhibited higher levels of apolipoprotein B (apoB), glucose, apoA1, blood pressure (BP), waist-hip ratio (WHR), and body mass index.
• Logistic regression identified apoB, high-density lipoprotein cholesterol (HDL-C), and non-HDL-C as significantly associated with the presence of carotid plaques.
• cIMT showed significant correlations with obesity parameters, BP, apoB, glucose, and liver enzymes, with regression analysis highlighting apoB, systolic BP (SBP), and WHR as key predictors.

Conclusions:

• Apolipoprotein B-containing lipoproteins and low HDL-C are implicated in the development of carotid plaques in FH patients.
• ApoB, elevated BP, and increased WHR are significant contributors to carotid intima-media thickness, reflecting subclinical atherosclerosis progression in FH.
