Role of Carotid Artery Screening Before Coronary Artery Bypass Graft Surgery

ABSTRACT

The incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. This study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in c and idates for coronary artery bypass graft [CABG] surgery. 1045 consecutive c and idates for CABG underwent carotid artery Doppler examination in a prospective study. The relation of age, sex, smoking and diabetes as well as lipid profile and carotid stenosis was evaluated In 1045 CABG c and idates with the mean age of 60 years, the prevalence of significant carotid stenosis [>60%] was 6.9%. In the patients who aged 65 years and older, significant stenosis was 12.5%. Age of 50 years and above, female gender hypercholesterolemia and diabetes mellitus are independent risk factors for significant carotid stenosis. Significant carotid stenosis has an earlier beginning in our study. Cost effectiveness studies are recommended for revising the previous screening protocols
