FREQUENCY OF CAROTID ARTERY DISEASE IN PATIENTS WITH LEFT MAIN STEM CORONARY DISEASE UNDERGOING CORONARY ARTERY BYPASS GRAFTING

Abstract

Objective: To assess the frequency of carotid artery disease in patients with leftmain stem coronary disease undergoing coronary artery bypass grafting.

Methodology: This cross sectional study was conducted in Department ofCardiovascular surgery Lady Reading Hospital Peshawar from July 2014 to June2016 for a period of two years. All the patients with Left main stem diseasereferred for coronary artery bypass grafting were scanned for carotid stenosiswith duplex scan. Patients with ongoing angina, hemodynamic instability,emergent CABG were excluded. The carotid stenosis 70% was consideredsevere while 50-69% was considered moderate.

Results: A total of 109 patients were included in the study. Of them 87(79.80%)were males. Mean age of the patients was 60.87 4.88 years. Out of total 109patients 69 (63.30%) patients had no carotid artery diseases or non significantdisease i.e. less than 50% stenosis, while 30 (27.5%) had moderate disease (50-69%stenosis). While 10 (9.20%) had severe carotid artery stenosis ( 70%).

Conclusion: There is high frequency of significant carotid artery stenosis inpatients with left main stem coronary disease. It is recommended that all thepatients with left main stem disease should be screened with carotid duplex scanto decrease neurological complications during CABG.
