Key result
Integrated functional, autonomic, and vascular testing may enhance early CVD risk detection in pediatric T1D.
Why the study?
Traditional clinical markers capture only part of CVD risk in youth with T1D and often fail to detect early autonomic, functional, or vascular changes.
Emerging tools such as functional testing, HRV, and wearables may improve early CVD risk detection in youth with T1D, though prospective validation and pediatric reference standards are needed.
Hypothesis-generating for integrated CV assessments in pediatric T1D; prospective validation and standards needed before adoption.
Background Cardiovascular disease (CVD) remains a major long-term complication of type 1 diabetes (T1D), with functional abnormalities emerging during childhood and adolescence. Traditional clinical markers, including blood pressure, lipids, body mass index, and glycemic indices, capture only part of cardiovascular risk and often fail to detect early autonomic, functional, or vascular changes. Objective To review emerging tools for early CVD risk assessment in youth with T1D, focusing on functional capacity, autonomic regulation, vascular stiffness, and digital health–enabled monitoring. Methods In this narrative review, we summarize and synthesize evidence from observational studies, pediatric cohorts, and translational research evaluating submaximal functional testing, heart rate variability (HRV), ambulatory blood pressure monitoring, pulse wave velocity (PWV), and wearable technologies in youth with T1D. Emphasis is placed on physiologic relevance, feasibility in clinical settings, and limitations of current data. Clinical Implications Integrating functional, autonomic, and vascular assessments, interpreted using age- and sex-specific norms, longitudinal trends, and composite profiles, may enhance early identification of cardiovascular vulnerability in pediatric T1D. Key gaps include the need for pediatric reference standards, actionable thresholds, and prospective studies to determine whether these markers predict outcomes or respond to targeted interventions.
