We tested 6 variants related to carotid atherosclerosis for replication and association to other vascular beds in SMART.
We replicated the association of 4 SNPs (p < 0.05), with a direction of effect similar to previous reports (binomial p = 0.03).
One SNP was associated with CAD (odds ratio = 1.24, 95% C.I. 1.08–1.42, p = 2 × 10−3), adding evidence to previous reports.
A genetic risk score based on cIMT-related SNPs was associated with cIMT (p = 1 × 10−3).
The genetic risk score was not associated to clinical events during follow-up (p = 0.86).
