compared to control people (0.65 ± 0.02 mm and 0.65 ± 0.02inm correspondingly). Similar IMT results

were also reported in carotid bifurcation site (0.87 ± 0.19 (R) & 0.89 ± 0.19mm (D) in IHD group

compared to control group (0.78 ± 0.03 mm both in R& L). However only IMT at left common carotid

considerably related to number of diseased coronary vessels. Conclusions: IMT at common carotid and

carotid bifurcation increased with age, significantly higher in IHD group compared to control group. Left

common carotid IMT was independent predictor of at least one diseased coronary vessel need intervention.
