Prolonged hyperlipidemia exposure increases the risk of arterial stiffness in young adults: a cross-sectional study in a cohort of Chinese

BackgroundHyperlipidemia is associated with arterial stiffness. Herein, We examined the effect of prolonged exposure to hyperlipidemia on the risk of arterial stiffness in young adults.MethodsA study cohort (35-55years old) that received health check-ups in the Kailuan study (2014-2016) were assessed. Hyperlipidemia was defined as a low-density lipoprotein cholesterol >= 160mg/dL according to the Chinese Guidelines for the Management of Dyslipidemia in Adults. Subjects were divided into three groups based on the number of years with hyperlipidemia: normal (0years), low exposure (1-5years), and high exposure (5-10years) groups. Arterial stiffness was defined as brachial-ankle pulse wave velocity>1400cm/s. For all subjects and subjects that did not meet statin treatment criteria under guidelines, logistics regression was used to analyze the effect of prolonged hyperlipidemia exposure on arterial stiffness in different age groups.ResultsAmong 12,431 subjects, the mean age was 46.425.34years with 9000 men (72.4%). Brachial-ankle pulse wave velocity gradually increased with increased exposure duration. Logistic regression analysis showed that hyperlipidemia exposure was a risk factor for arterial stiffness in the low (1.22 times) and high (1.49 times) exposure groups compared with the normal group. In the different age groups, the risk of arterial stiffness increased with the duration of hyperlipidemia exposure, apart for the 35-40-year-old population. The effect of hyperlipidemia exposure duration on arterial stiffness in young adults that did not meet statin treatment criteria under guidelines was similar to the general population.ConclusionsProlonged exposure to hyperlipidemia in young adults increases the risk of arterial stiffness. Young adults with this condition may benefit from more aggressive primary prevention.Trial registrationName of the registry: Risk factors and intervention for cardiology, cerebrovascular and related disease (Kailuan Study)Trial registration number: CHiCTR-TNC1100 1489Date of registration: Aug 24, 2011 p id="Par URL of trial registry record
