Abstract

Background: Diabetes mellitus is a widespread disease. Its vascular complications can be characterized by arteriosclerosis formation in carotid arteries. Due to its delayed diagnosis resulting in more complications in Iran, it seems that screening diabetic patients is mandatory.

Objectives: The aim of this study was to compare the intima-media thickness (IMT) of carotid artery in diabetic and non-diabetic patients.

Patients and methods: This is a cross-sectional study, which included 80 participants (40 diabetics and 40 non-diabetics). By using ultrasound, bilateral IMTs of the distal carotid were measured and the data were analyzed using ANOVA and multivariate regression tests in SPSS 14.

Results: The mean IMT was 0.97 in diabetic patients and 0.63 in non-diabetics (P < 0.001). Age and gender had significant positive effects on the increase of IMT (P < 0.05 and P < 0.005, respectively for age and gender). Past medical history of coronary heart disease (CHD) and cerebrovascular accident (CVA) in diabetes is associated significantly with an increase in IMT (P =0.019 and 0.027 respectively). Other confounding variables such as smoking, history of hypertension (HTN) and hyperlipoproteinemia (HLP) in diabetic patients showed no significant relationship with the increase of IMT.

Conclusions: Although measuring the IMT of the carotid artery by sonography is a useful tool for screening diabetic patients, more studies are needed for determining how to use these measurements in promoting the patients outcomes.
