High-Sensitivity Cardiac Troponin T in Healthy Sport-Participating Youth Aged 8-16 Years: Reference Values From the Cor-School Cohort.

ABSTRACT:

Objectives

High-sensitivity cardiac troponin T (hs-cTnT) is widely used in adult cardiology, yet pediatric reference values remain scarce. This study aimed to establish reference values for hs-cTnT in healthy sport-participating youth aged 8-16 years from Spain; to examine differences by age, sex, and pubertal stage; and to explore associations with anthropometry and physical activity.

Methods

This cross-sectional study used baseline data from the Cor-School cohort, including 733 organized sport participants aged 8-16 years from northeastern Spain. Anthropometry, pubertal status, biological maturity, and PHV timing were assessed alongside hs-cTnT and habitual physical activity. Percentiles were calculated from detectable hs-cTnT concentrations below the 99.75th percentile. G
