Key result
A history of coronary artery bypass graft was a significant predictor of carotid artery stenosis ≥50% in elderly males with cardiovascular disease (OR 2.70; 95% CI 1.40-5.19; P=0.003).

There is a high prevalence (27.8%) of significant carotid artery stenosis in elderly males with cardiovascular disease, with prior CABG being a strong predictor.
Prior CABG was associated with carotid stenosis in elderly males with CVD; hypothesis-generating for targeted screening and requires prospective confirmation.
This study investigated the prevalence of carotid artery stenosis (CS) and the association with various risk factors in male patients (>65 years) diagnosed with cardiovascular diseases. Duplex sonography of the carotid arteries was performed in 434 of 473 eligible patients of whom 118 (27.8%) patients had significant CS ≥50%. The prevalence and severity of CS did not differ between patients who presented with neurological symptoms or acute coronary syndrome/peripheral artery disease (30.8% vs 25.9%, respectively). Among patients with CS, a higher rate of current smoking, a higher systolic blood pressure, and a lower glomerular filtration rate were observed compared with patients without CS. A history of coronary artery bypass graft was a significant predictor of the presence of CS (P = .003, odds ratio [OR] = 2.70 [1.40-5.19]). The prevalence of CS in elderly males with manifest atherosclerotic disease is high, irrespective of presenting clinical manifestation.

Kazemi‐Bajestani et al. (2012) conducted a cross-sectional in Cardiovascular diseases (n=434). History of coronary artery bypass graft vs. No history of coronary artery bypass graft was evaluated on Presence of carotid artery stenosis ≥50% (OR 2.70, 95% CI 1.40-5.19, p=.003). A history of coronary artery bypass graft was a significant predictor of carotid artery stenosis ≥50% in elderly males with cardiovascular disease (OR 2.70; 95% CI 1.40-5.19; P=0.003).
