Preoperative Carotid Artery valuation in 1045 Patients Undergoing Coronary Artery Bypass Graft Surgery

Backgrounds/objectives: to evaluate the prevalence of significant carotid artery stenosis and its determining factors in candidates of coronary artery bypass graft (cabg) surgery. patients and methods: 1045 consecutive cabg candidates underwent carotid artery doppler examination in a cross sectional study. the relation of age, gender, history of smoking and diabetes, as well as lipid profile to significant carotid stenosis was evaluated. results: in study subjects, mean age of 60.57±9.3 years, the prevalence of significant carotid stenosis (>60%) was 6.9%. in subjects older than 65 years the significant stenosis tolled to 12.5%. over 50 years of age, female gender, hypercholesterolemia and diabetes were independent determining factors for significant carotid stenosis. conclusion: significant carotid stenosis has significantly higher prevalence among patients over 50 years of age. cost benefit studies are recommended to revise the current evaluation protocols.
