Felicitas U. Idigo et.al. conducted a study conducted a study to determine if lipid profile parameters could serve as predictors of carotid intima-media thickness. The researchers concluded that they are not significant predictors and thus combining them with CIMT does not improve the diagnostic sensitivity of sonography in atherosclerosis screening.
Objective. The purpose of this prospective study was to ascertain if lipid profile parameters could serve as predictors of carotid intima-media thickness (CIMT), which, when combined, may improve the sensitivity of sonographic CIMT measurement in the diagnosis of subclinical atherosclerotic changes.
Methods. The lipid profiles and CIMT of 181 subjects without cardiovascular risk factors were measured at the internal, external, common, and bulbar segments.
Results. The mean CIMT values obtained were 0.620 ± 0.055 cm for men and 0.575 ± 0.051 cm for women, and the η2 values (η2 < 0.04) were used as a measure of association. Across all segments of both carotid arteries, lipid profiles were significantly and moderately associated with but not predictive of CIMT (fasting blood sugar, total cholesterol, and low-density lipoprotein: η2 = 0.99–0.24).
Conclusions. Although lipid profiles were moderately associated with CIMT, they are not significant predictors; hence, combining them with CIMT does not improve the diagnostic sensitivity of sonography in atherosclerosis screening.
