Key result
SYNTAX scores of 22 or higher are linked to significantly greater carotid artery severity.
Why the study?
Carotid artery disease and coronary artery disease share atherosclerotic mechanisms, but the relationship between carotid artery stenosis severity and coronary anatomical complexity assessed by SYNTAX Score needed evaluation.
Does the anatomical complexity of coronary artery disease correlate with the severity of carotid artery stenosis?
Observational (n=45)
No
Does the anatomical complexity of coronary artery disease correlate with the severity of carotid artery stenosis?
The severity of carotid artery stenosis is significantly correlated with the complexity of coronary artery disease as measured by the SYNTAX score, suggesting that patients with complex CAD should be screened for carotid disease.
Answers are grounded in this paper and cite their sources.
Suggests targeted carotid evaluation in complex CAD; leaves open whether screening improves outcomes.

Erdoğan et al. (2021) conducted an observational in Coronary artery disease and carotid artery stenosis (n=45). Intermediate-high SYNTAX Score (≥22) vs. Low SYNTAX Score (<22) was evaluated on Carotid artery severity score (r=0.47, p=0.001). Patients with an intermediate or high SYNTAX score (≥22) had a significantly higher carotid artery severity score compared to those with a low score (<22) (median 3 vs 1, p=0.001).
