Introduction: Patients with type 2 diabetes represent 50% of all sudden cardiac deaths. Disseminated arteriosclerotic lesions are the cause of vascular incidents that cause permanent disability resulting from lower limb amputations.
Objectives: Our study was designed to investigate the relationship between asymmetrical dimethylarginine (ADMA), symmetric dimethylarginine (SDMA) plasma concentration and intima-media thickness (IMT) in subjects with diabetes mellitus without vascular complications (group A) and a group of diabetic patients diagnosed with diabetes micro- and macroangiopathy (group B).
Patients and method: The experimental groups included 42 diabetic patients. Group A - 22 patients (9 W and 13 M), free from vascular complications (mean age 55.83±7.37 years), group B - 20 patients (6 W, 14 M) with accompanying micro- and macropathic changes (mean age 63.80±8.79 years). Group C (n=22), the control group, consisted of healthy volunteers (12 W and 10 M), between the ages of 40 to 60 (mean age 51.16±6.39), selected in reference to the age and sex of the research group. The carotid artery intima-media complex thickness (IMT) was evaluated with the use of a duplex ultrasound.
Conclusions: There was no correlation between ADMA and the maximal or mean intima-media thickness (IMT) of the common carotid artery (CCA) and internal carotid artery (ICA). We demonstrated a correlation between symmetric dimethylarginine (SDMA) concentration and CCA IMT. The results suggest that ICA IMT may serve as a marker of vascular complication among patients with diabetes.
