Statin therapy increases carotid plaque echogenicity in hypercholesterolemic patients

Area of Science:

• Cardiology
• Vascular Biology
• Pharmacology

Background:

• Pharmacologic stabilization of carotid artery plaques is crucial for preventing ischemic stroke.
• Hypercholesterolemia is a significant risk factor for atherosclerotic plaque development.
• Understanding plaque characteristics, like echogenicity, can inform treatment strategies.

Purpose of the Study:

• To investigate the impact of 12-month statin therapy on carotid plaque echogenicity in hypercholesterolemic patients.
• To assess changes in plaque thickness and inflammatory markers alongside echogenicity.
• To evaluate the efficacy of statins in modifying atherosclerotic plaque characteristics.

Main Methods:

• Inclusion of 81 hypercholesterolemic patients with carotid atherosclerotic plaques.
• Ultrasound with integrated backscatter analysis to evaluate plaque echogenicity.
• 12-month monitoring of plaque thickness, echogenicity, and serum inflammatory markers (hs-CRP, IL-6, IL-18) in statin-treated and control groups.

Main Results:

• Statin therapy significantly increased carotid plaque echogenicity and decreased plaque thickness.
• Significant reductions in total cholesterol, triglyceride, hs-CRP, and IL-18 were observed post-statin treatment.
• No significant alterations in plaque echogenicity, thickness, or inflammatory markers were noted in the non-statin group.

Conclusions:

• Statin therapy for 12 months enhances carotid plaque echogenicity and reduces plaque thickness in hypercholesterolemic individuals.
• Statin treatment effectively lowers serum lipid levels and key inflammatory markers, contributing to plaque stabilization.
• These findings support statin therapy as a valuable strategy for managing carotid atherosclerosis and reducing stroke risk.
