Association Between Lipid Profiles and Arterial Stiffness in Chinese Patients With Hypertension: Insights From the CSPPT

摘要

Arterial stiffness plays a key role in the pathogenesis of cardiovascular disease. However, the relationship between lipid levels and arterial stiffness is controversial. We aimed to investigate the association between lipid parameters and brachial-ankle pulse-wave velocity (baPWV) in Chinese patients with hypertension. A total of 14 071 participants with hypertension in the China Stroke Primary Prevention Trial (CSPPT) were enrolled in the present study. Patients were assigned to 4 equal groups according to their baPWV. Participants in the highest baPWV group were older with a higher prevalence of stroke and diabetes mellitus as well as higher body mass index (BMI), blood pressure, fasting plasma glucose, uric acid, total cholesterol (TC), triglycerides (TG), homocysteine (Hcy), and vitamin B12 levels (P < .001). After adjusting for age, sex, BMI, and other cardiovascular risks, high-density lipoprotein cholesterol (HDL-C) was negatively related to baPWV (beta = -0.22, P = .012), TC (beta = 0.08, P = 0.001), TG (beta = 0.14, P = .001); non-HDL-C (beta = 0.12, P = .001) and positively related to baPWV. The effect was not observed for low-density lipoprotein cholesterol (LDL-C; beta = 0.12, P = .335).These results suggested that non-HDL-C, TG, and TC were associated with arterial stiffness in a Chinese population with hypertension. HDL-C was inversely associated with arterial stiffness.
