Several lipid parameters are closely associated with residual cardiovascular risk. We aimed to confirm that in a range of low-density lipoprotein cholesterol (LDL-c) levels (from <70 mg/dl to ≥160 mg/dl), other lipid parameters, such as triglyceride (TG) level, non-high-density lipoprotein cholesterol (non-HDL-c) level, and the total cholesterol (TC)/HDL-c ratio, are still related to arterial stiffness, which is a recognized marker of atherosclerosis. In this cross-sectional study, we measured brachial-ankle pulse wave velocity (baPWV), as well as clinical and biochemical indices in 16,733 Chinese adult volunteers who underwent health check-ups from January 2014 to January 2015. Arterial stiffness was defined as the upper quartile of baPWV. We applied multivariable logistic regression models to examine the associations between lipid parameters and arterial stiffness. Both men and women with high baPWV were more likely to have an atherogenic lipid phenotype. Among participants with LDL-c <70 mg/dl, participants with non-HDL-c ≥100 mg/dl had a multivariable adjusted OR for arterial stiffness of 1.66 (1.11-2.50) compared to those with non-HDL-c <100 mg/dl; participants with TG ≥150 mg/dl had an OR of 2.44 (1.61-3.71) compared to those with TG <150 mg/dl; and participants with a TC/HDL-c ratio ≥4 had an OR of 1.74 (1.15-2.65) compared to those with a TC/HDL-c ratio <4. Similar results were observed at other LDL-c levels. We found that non-HDL-c, TG, and the TC/HDL-c ratio were consistently associated with arterial stiffness in a range of LDL-c levels, even when LDL-c was below 70 mg/dl. These lipid measures are related to residual cardiovascular risk, possibly due to their detrimental effects on vascular structure.
