Introduction: Biological rather than chronological age (C-age) drives deviation from healthy aging. This study aimed to identify a plasma metabolomic signature indicative of age-related cardiovascular risk (pMTB-age) predicting vascular morbidity and mortality. Methods: = 811 [2001]). Results: The trained model (pMTB-age), relating C-age to the plasma metabolome derived by elastic net regression, included 18 metabolites (six amino acids) and explained from 28.6% to 22.9% of C-age in the discovery and replication data. Feature importance of the retained metabolites derived by SHapley Additive exPlanation showed large interindividual variability in the relation between C-age and pMTB-age. In Flemish and Spanish, cardiovascular risk factors were significantly associated with C-age, pMTB-age, and pMTB-age uncorrelated from C-age (pMTB-age-R). In Flemish (median follow-up 12.3 years) and Spanish (18.8 years), mortality and cardiovascular complications correlated with C-age and pMTB-age. In Flemish, cardiac endpoints (hazard ratio [95% CI] 1.28 [1.00-1.63]) and its components kept significance in relation to pMTB-age-R. The pathway analysis revealed overrepresentation of glycine, serine, and threonine. Conclusions: pMTB-age is a multidimensional biomarker, which identifies individuals with accelerated vascular aging with high precision and combined with the pathway analysis highlights the role of amino acids in vascular disease. Therefore, pMTB-age can guide risk stratification and the personalized and timely prevention and treatment tailored to an individual's unique pMTB-age profile.

Introduction: Aortic wall calcification increases arterial stiffness which is often assessed by carotid-femoral pulse wave velocity (cfPWV). However, the impact of kidney function upon the association between…
Background: Dengue virus infection is one of the major public health concerns in Bangladesh. Recently, dengue is drastically spread out in all main cities as well as rural areas. There are four serotypes of dengue…
Introduction: Age-related arterial remodeling is a key contributor to cardiovascular disease, but morphological changes in cerebral arteries with aging remain poorly characterized. We aimed to investigate age-related…
