Lipoprotein ratios are better than conventional lipid parameters in predicting arterial stiffness in young men.
Although dyslipidemia is associated with cardiovascular disease, there are conflicting data about the role of serum lipids and their ratios in promoting arterial stiffness. The authors aimed to compare serum lipid profiles to predict arterial stiffness, which was assessed by brachial-ankle pulse wave velocity in young Chinese men. A total of 1015 participants aged 18 to 44 years without serious comorbidities were recruited for conventional detection. Anthropometrics, brachial-ankle pulse wave velocity, serum lipids, and other laboratory data were measured. Univariate analysis and multivariate logistic regression were performed to examine the relationship between serum lipid profiles and brachial-ankle pulse wave velocity. Participants with high brachial-ankle pulse wave velocity exhibited higher levels of total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol (HDL-C), total cholesterol/HDL-C, TG/HDL-C, low-density lipoprotein cholesterol/HDL-C, and non-HDL-C/HDL-C. The subsequent multivariable logistic regression showed that TG/HDL-C, total cholesterol/HDL-C, non-HDL-C/HDL-C, and TG significantly increased the risk for arterial stiffness after adjustment for confounding factors. Results indicate that lipid ratios are superior to conventional lipid parameters for predicting arterial stiffness in young men and that the TG/HDL-C ratio has the strongest association with arterial stiffness.
