Evaluation of Carotid Artery Disease in Patients with Coronary Artery Disease Eligible for Coronary Artery Bypass Graft Surgery

INTRODUCTION There is an increased incidence of TIA and stroke in patients undergoing Coronary Artery Bypass Grafting (CABG). The risk of stroke is increased in patients with significant carotid artery stenosis. Because most of the patients with significant carotid stenosis are asymptomatic, it is mandatory to screen the status of carotid arteries prior to CABG. AIMS AND OBJECTIVES Study the occurrence of carotid artery disease in patients who are candidates for CABG. STUDY DESIGN Cross sectional observational RESULTS AND OBSERVATIONS The prevalence of carotid artery disease 50-70 % was 7.1 % and greater than70 % was 6.2 %, based on Doppler.18.75 %patients who were having 50-70 % stenosis based on doppler found to have insignificant stenosis on selective carotid angiography. While 7.1 % patient who were having greater than70 % stenosis based on doppler, have insignificant stenosis on carotid angiography. So actual prevalence of carotid artery disease 50-70 % was 6.6 % and greater than70 % was 5.8 %, based on carotid angiography. CONCLUSION This study showed a high proportion of marked carotid artery disease in patients who were for CABG. Carotid doppler can be used as screening test for carotid artery disease. Selective carotid angiography should be done who are having significant carotid stenosis on carotid doppler in same setting while patient undergo for coronary angiography.
