Key result
Severe carotid occlusive diseases were found significantly more frequently in candidates for coronary artery bypass grafting compared to those for non-CABG cardiovascular surgery (11.9% vs. 4.1%, p<0.05).
Why the study?
What is the prevalence and what are the risk factors for severe carotid occlusive disease in patients undergoing elective cardiovascular surgery?

What is the prevalence and what are the risk factors for severe carotid occlusive disease in patients undergoing elective cardiovascular surgery?
Absolute Event Rate: 11.9% vs 4.1%
p-value: p=<0.05
Preoperative carotid screening is particularly indicated for CABG candidates with diabetes or atherosclerotic disease, and non-CABG candidates with a history of stroke, due to a higher risk of severe carotid stenosis.
Supports targeted preoperative carotid screening in CABG candidates; leaves open whether routine screening improves outcomes in non-CABG surgery.

Saito et al. (1999) conducted an observational in Candidates for elective cardiovascular surgery (n=388). Coronary artery bypass grafting (CABG) candidate vs. Non-CABG cardiovascular surgery candidate was evaluated on Prevalence of severe carotid occlusive diseases (stenosis >75% or side-to-side ratio of end-diastolic blood flow velocity >1.4) (p=<0.05). Severe carotid occlusive diseases were found significantly more frequently in candidates for coronary artery bypass grafting compared to those for non-CABG cardiovascular surgery (11.9% vs. 4.1%, p<0.05).
