To examine ethnic differences in carotid bulb morphology between Asian and White individuals and its potential implications for atherosclerosis and ischemic stroke, particularly in understanding population-specific vascular anatomy.
Key Findings:
Significant ethnic differences in carotid bulb geometry were observed.
CB/ICA diameter was lower in Asian participants (1.57) compared to White participants (1.68; p < 0.001).
After adjustment, the difference in CB/ICA remained significant (−0.09; 95% CI -0.14 to −0.04; p < 0.001).
No significant interethnic difference in ICA diameter; carotid bulb diameter was smaller in Asian participants.
Adjusted differences were also noted for CB/CCA, ICA/CCA, and ECA/ICA.
Interpretation:
Differences in carotid bifurcation geometry between Asian and White adults may influence local hemodynamics, potentially affecting susceptibility to plaque formation and atherosclerosis.
Limitations:
Cross-sectional design limits causal inferences.
Study population may not represent all Asian and White individuals, particularly in terms of geographic and lifestyle factors.
Conclusion:
Carotid bifurcation geometry varies between Asian and White populations, which may have implications for understanding ethnic differences in atherosclerosis and stroke risk.
