Remnant cholesterol is a risk factor for cardiovascular disease, especially when low-density lipoprotein cholesterol (LDL-C) levels are normal. However, there are few studies on the relationship between remnant cholesterol and subclinical atherosclerosis. Common carotid artery intima-media thickness (cIMT) is an imaging marker of subclinical atherosclerosis. This study aimed to investigate the relationship between remnant cholesterol and cIMT in a community population with normal LDL-C. This study is a retrospective analysis; 1,101 community population with available carotid artery imaging and fasting lipid data with LDL-C <4.1 mmol/L were included in this analysis. Remnant cholesterol was calculated as total cholesterol minus LDL-C minus high-density lipoprotein cholesterol. Abnormal cIMT was defined as maximum cIMT value ≥1 mm. Logistic regression was used to assess the relationships between remnant cholesterol levels and abnormal cIMT. As the remnant cholesterol level increased from the lowest to the highest quartile, the rate of abnormal cIMT increased from 24.5% to 38.6% (p trend <0.001) in the community population with normal LDL-C level. In the unadjusted model, the odds ratios (ORs, 95% confidence intervals) in the highest quartile group were 1.937 (1.338-2.803) for abnormal cIMT compared with the lowest quartile. The multivariable-adjusted ORs (95% confidence intervals) for the highest versus lowest quartile of remnant cholesterol were 2.132 (1.420-3.202) for abnormal cIMT. Elevated fasting remnant cholesterol levels were positively associated with abnormal cIMT in community population with normal LDL-C levels. Remnant cholesterol may be an important indicator of risk stratification in community population with normal LDL-C level.
