Abstract

Background Coronary artery disease (CAD) is associated with high mortality around the world, hypertension, diabetes and smoking are common risk factors for CAD. Aim of the Work Our study aims to explore the relationship between CIMT and coronary artery disease (CAD) in patients evaluated by coronary angiography for suspected CAD. Patients and Methods This cross-sectional study was carried out in radiology department, Faculty of medicine, Ain Shams University. All patients gave their written informed consent for taking part in this study. The study was approved by Ethical Committee of Faculty of medicine, Ain Shams University. It included 30 patients that were referred for MDCTA for coronary arteries study and IMT measuring by ultrasonography, Patients were referred for coronary CTA because of known or suspected coronary artery disease (CAD). Results We conducted our study on 30 patients 80% were males and 20 % were females aged between 30-70 years by using ECG gated 128 MDCT then ultrasonography examination for CIMT evaluation, Patients were referred for coronary CTA because of known or suspected CAD. 60% of cases were smokers, 66.7% of cases had hypertension, 73.3% had DM and 63.3 % had hyperlipidemia. Both imaging modalities showed overall good agreement and the concordance was better for moderate and higher grades of atherosclerosis than for low grade. Conclusion Higher values of CIMT were found in patients with various coronary risk factors (DM, Hypertension and hyperlipidemia). Carotid duplex ultrasonography provides a simple, easy and non-invasive tool for detection of CAD. It can be used as a predictor for incidence of CAD. There was also a significant relation between CIMT and the extent of CAD, noted as increased number of coronary vessels affected. Finally we demonstrated the usefulness of carotid intima media thickness in predicting coronary artery disease.
