Key result
Maximum carotid intima-media thickness varied significantly across circumferential angles (p < 0.001), confirming an asymmetrical helix-like distribution of atherosclerosis.
Why the study?
Is the asymmetrical distribution of carotid atherosclerosis consistent across age, race, and gender?

Confirms helical carotid atherosclerosis pattern across risk strata; leaves open whether this refines CIMT-based risk stratification in practice.

Yes
Is the asymmetrical distribution of carotid atherosclerosis consistent across age, race, and gender?
p-value: p=<0.001
Carotid atherosclerosis exhibits a consistent asymmetrical helix-like distribution across different ages, genders, and races, highlighting the importance of standardizing the angle of insonation in carotid ultrasound studies.
Tajik et al. (2011) conducted a cross-sectional in Carotid atherosclerosis (n=3,364). Circumferential angle of carotid artery vs. Other angles was evaluated on Differences in maximum CIMT across circumferential angles (p=<0.001). Maximum carotid intima-media thickness varied significantly across circumferential angles (p < 0.001), confirming an asymmetrical helix-like distribution of atherosclerosis.
