Abstract

Objective: It was the aim of this study to investigate whether there is any relationship between oxidative stress, as assessed by the diacron reactive oxygen metabolite (d-ROM) test, and carotid atherosclerosis among hypercholesterolemic patients.

Subjects and methods: A well-defined group of patients with type II hypercholesterolemia (n = 81, mean age 59 years) was studied to observe the correlation between the levels of serum d-ROMs and carotid artery intima-media thickness (IMT) using B-mode ultrasound, in relation to the traditional atherosclerotic risk factors (age, sex, smoking, body mass index, blood pressure, glucose and lipid panels).

Results: The mean level in low-density lipoprotein cholesterol (LDL-C) in this population was 4.45 mmol/l, d-ROMs were 323.2 Carr U, and IMT was 0.91 mm. A multiple regression analysis revealed a positive and significant correlation between IMT and d-ROMs (β = 0.27, p < 0.05), along with age and LDL-C.

Conclusion: These results indicate that the increased oxidative stress levels using the d-ROM test, independent of aging and increased LDL-C levels, may be associated with carotid atherosclerosis even in hypercholesterolemic patients.
