Abstract :

Arteriosclerotic Vascular Disease is a syndrome affecting arterial blood vessels. Rupture leads to narrowing, Flow obstruction, infarction and aneurysm Formation with rupture of vessel. Asymptomatic patients have no complaints and can only be detected through screening or by chance. Imaging can be done either by invasive methods like direct angiography of vessels or by non–invasive methods, such as carotid doppler/CT–angiography or MR–angiography. A retrospective observational study was carried out over a span of 2 yrs among 623 participants undergoing non–emergent coronary angiography and subsequent coronary artery bypass surgery at a tertiary care centre of New Delhi. Carotid Artery Stenosis (CAS) was evaluated by a consultant radiologist. The patients underwent carotid ultrasound and Doppler study within 24 hours of the coronary procedure. Prevalence of Carotid Artery Stenosis (CAS) was found to be 38%. The prevalence of both unilateral and bilateral disease was 19 %. Age and Smoking (Tobacco) was found to be risk factors for CAS. Diabetes (insulin resistance) was also found to be a significant predictor of CAS. Thus the study points toward the relatively wide prevalence of carotid artery disease in neurologically asymptomatic patients undergoing CABG for CAD in the elective setting.
