Its relationships with coronary artery disease risk factors, future cardiovascular events, allow it to serve as a suitable diagnosing method for coronary atherosclerosis. The purpose of this study was to investigate the CIMT detected by Ultrasonography as a clinically useful marker for the presence and severity of coronary artery disease (CAD). Materials and Methods: Two hundred consecutive patients (age from 30 ye80 y) who were subjected to coronary angiography also subjected for carotid B-mode ultrasound scan of carotid artery. The mean value of six measurements of IMT of far wall of the common carotid artery and at its bifurcation was calculated in each patient. Result: The mean IMT was significantly correlated to the number of stenosed coronary arteries. The mean CIMT in patients with single vessel disease, double vessel disease and for triple vessel disease was 0.580 ± 0.160 mm, 0.718 ± 0.206 mm and 0.934 ± 0.301 mm respectively, which was higher as compared to control group (0.465 ± 0.144 mm). Discussion: A significant linear correlation between IMT and advancing CAD observed by A Kablak-Ziembicka. Daniel H. O'Leary has reported the prevalence and severity of carotid atherosclerosis continued to increase with age even in the late decades of life. In the present study IMT thickness was increased with age and mean CIMT was found greater for significant CAD as compared to non-significant CAD and for normal coronary arteries thus CIMT may be a clinically valuable parameter in diagnosis of non-significant and significant CAD.
