Description
Summary:It has not been adequately studied which biomarkers for cardiovascular risk indicate changes of atherosclerosis by aging process. The current study aimed to investigate the characteristics of metabolic factors related to arterial stiffness in young and old adults. Our cross-sectional study enrolled 851 healthy young adults and 719 old adults. Metabolic biomarkers included glucose, lipid profiles, and liver enzymes. In young adults, additional biomarkers such as C-reactive protein, apolipoproteins, lipoprotein(a), ferritin, and 25-hydroxycholecalciferol were measured. Arterial stiffness was evaluated by measuring brachial-ankle pulse wave velocity (baPWV). The mean age was 37.8 and 65.1 years old in the young and old groups, respectively. Without adjustment, most parameters were significantly correlated with baPWV in both young and old groups. Mean baPWV was significantly different according to metabolic syndrome (MetS) in both groups (13.1 and 12.1 m/s in the young subjects with and without MetS, respectively; 17.4 and 15.8 m/s, respectively, in the old group). After adjusting for age, sex, and hemodynamic factors, the difference in baPWV according to MetS was significant only in the old group. The relationship between most biomarkers and baPWV was influenced by metabolic disorders such as hypertension and diabetes in old adults. Total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), and apolipoprotein B were significant in young group. In conclusion, the metabolic biomarkers related to arterial stiffness were different between young and old adults. Contrary to old adults, TC, LDLC, and apolipoprotein B were independent biomarkers for arterial stiffness in healthy young adults.
