Glycated Hemoglobin Level Is Strongly Related to the Prevalence of Carotid Artery Plaques With High Echogenicity in Nondiabetic Individuals
Background— High levels of HbA 1c have been associated with increased mortality and an increased risk of atherosclerosis assessed as carotid intima-media thickness or plaque prevalence. In the present population-based study, we examined the association between HbA 1c and plaque prevalence with empha...

HbA 1c was categorized into 5 groups: <5.0%, 5.0% to 5.4%, 5.5% to 5.9%, 6.0% to 6.4% and >6.4%. Carotid plaque prevalence increased with increasing HbA 1c level ( P for linear trend=0.002).

The risk of predominantly hard plaques was also significantly associated with HbA 1c levels, although the ORs at each level were somewhat lower than for hard plaques. With respect to the risk of soft plaques versus no plaques, no statistically significant relationship with HbA 1c levels was found. Conclusions— Metabolic changes reflected by HbA 1c levels may contribute to the development of hard carotid artery plaques, even at modestly elevated levels.
