Abstract

Background and aims: Concomitant carotid artery disease (CaAD) in patients referred to coronary surgical revascularization is a strong hazard to perioperative stroke. The current study addressed the epidemiology features of concomitant CaAD in patients referred to a coronary surgical revascularization center.

Methods: This descriptive-analytical cross-sectional study was conducted on all incoming patients to coronary surgical revascularization for two years at a single center who underwent a color duplex-sonography (CDS) interrogation. The demographic, clinical, echocardiographic, coronary angiographic, and color duplex-sonographic data were collected from patients’ medical records. Quantitative and qualitative data were expressed as means and standard deviations, as well as numbers and percentages, respectively. The relationships between quantitative and qualitative variables were investigated using Pearson’s correlation and chi-square test, respectively.

Results: In total, 430 patients with a mean age of 66.3±9.9 years were included (35% females) in the study. Preoperative CDS was performed on 82% of patients; in addition, 29% of them presented with an increased intima-media ratio, and CtAD was observed in 51%. Based on the results, 77 and 143 patients were detected with unilateral and bilateral involvement, respectively. Severe carotid stenosis accounted for 4% of patients. Age older than 65 years (P=0.02), unstable angina (P=0.045), and the presence of an occluded coronary artery (P=0.002) were associated with the presence of CtAD. Finally, the severity of the left and right carotid stenosis was associated with diabetes mellitus (P<0.05).

Conclusion: The prevalence of concomitant CtAD in patients referred to coronary surgical revascularization remains high. The current data warn of the necessity of performing preoperative CDS routinely.
