Association of telomeres length with cardiovascular risk factors and arterial stiffness

Abstract

Abstract Background Leukocyte telomere length (LTL) has been explored as a marker of biological aging, with connections established to age-related diseases like atherosclerosis. Studies have particularly associated telomeres with conditions such as peripheral vascular disease, coronary heart disease, and cardiovascular mortality. Methods In this cross-sectional analysis we enrolled individuals from "Corinthia" study which was conducted in the homonym region in Greece. We measured LTL in individuals to obtain comparative metrics on the prevalence of cardiovascular risk factors as well as arterial stiffness. Carotid-femoral pulse wave velocity (cfPWV) was used to evaluate arterial stiffness. Results Our analysis included 419 individuals aged 62.4 ± 11.8 years with a median LTL at 6.78 (IQR: 5.08-8.72) bp. Using the median LTL as a cutoff, the cohort was divided into two groups, Group A: 208 patients with low LTL, Group B: 211 patients with high LTL. Group A exhibited a significantly higher proportion of males (52.4% vs. 34.1%, p < 0.01), higher body mass index (BMI) (29.3 ± 4.7 kg/m2 vs. 28.5 ± 4.4 kg/m2, p <0.05), and a higher prevalence of hypertension (78.8% vs. 67.8%, p = 0.01) and dyslipidemia (51% vs. 38.9%, p = 0.014). No significant difference was observed regarding the prevalence of diabetes mellitus, smoking habits, and established cardiovascular disease. In the analysis of the whole cohort, cfPWV was found significant higher in Group A (9.61 ± 3.46 m/s vs. 8.38 ± 2.49 m/s, p <0.01) compared to group B (Figure, Panel A). This association remained significant (β = -0.096, p = 0.038), even after adjustment for confounders in the multivariate regression analysis. Finally, a statistically significant negative correlation between LTL and cfPWV was observed (Figure, Panel B). Conclusion LTL plays a pivotal role in cardiovascular health, and lower LTL is associated with impaired cfPWV values and a heightened prevalence of obesity, hypertension, and dyslipidemia.Asociation of LTL with cfPWV values.
