ABSTRACT

Background: Atherosclerosis is a generalized disease, mainly manifested in all vascular trees. An association between carotid artery stenosis and coronary artery disease has been well established. Carotid artery stenosis is an important etiologic factor for cerebrovascular accidents, is associated with coronary artery disease. Methods: A prospective study of 86 patients, who were scheduled for CABG, was done at radiology department, Medical city Baghdad, Gazzi Al-Harirri hospital from Nov.2016 to July 2017. The majority were males, (73) and (13) were Females. All patients, after a clinical history was taken by the cardiac surgery team, they underwent a physical examinations, and investigations; chest x-ray, ECG, blood was taken for fasting blood suger and cholesterol study, Doppler ultrasonography for bilateral carotid arteries were performed by aspescailized radiologist for carotid artery atherosclerosis. Results: The majority of the patients were above 50 years of age, 73 patients (84.45%) and only 15% were below the age of 50 years. ale affected by carotid artery atherosclerosis, (76.7%) more than females above the age of 50 years, while below the age of 50 years females (46.7%) more affected than males (9.58%). Risk factors were significantly correlated with both carotid and coronary artery stenosis like age, sex, smoking hypertension, cholesterol and diabetes mellitus. Doppler Ultrasonography was performed to screen the presence of carotid artery stenosis. Carotid artery atherosclerosis was present in 66 patients, (76.7%). Ten patients (15.1%) with one coronary artery disease, 17(25.75%) with two coronary artery disease, and 39 patients (59.09%) with three coronary artery disease. The location of atherosclerosis is mostly in ICA, (53%), of which 15% in the bulb, in the CCA (32%). Conclusions: Our finding indicated significant associations between carotid artery atherosclerosis and coronary artery disease. There is strong association between increase in intma media thickness of carotid arteries and the presence of coronary artery disease.
