Objective: To investigate the relationship between intima-media thicknesses (IMT) of carotid and superficial femoral arteries and coronary artery calcium index quantified using Agatston score.

Materials and Methods: Cardiac multidetector computed tomography (MDCT) angiography of 75 patients were included in the study. Coronary artery calcium scores were measured using a workstation. Calcium scores were calculated according to the Agatston method. Bilateral carotid artery and superficial femoral artery IMTs were obtained by B-mode ultrasound. All patients were divided into three groups according to Agatston scores. 25 patients with 0 Agatston score were included to first group. 25 patients with 1-100 and 25 patients with more than 101 Agatston score were included to second and third group, respectively. Oneway Anova, t test and Post HocTukey HSD test were used for statistical analysis. Values of P< 0.05 were considered statistically significant.

Results: There was a significant relationship between carotid artery and superficial femoral artery IMTs and coronary artery calcium score index. Increased calcium scores were related with increasing IMTs.

Conclusion: Increased carotid artery and superficial femoral artery IMTs relates with coronary artery calcium scores. Superficial femoral artery IMT measurement is reliable tool comparable to carotid artery IMT measurement.
