ABSTRACT
Cardiac troponin is commonly used to screen for cardiac diagnoses in pediatric patients, as it is only released by myocardial tissue. There is limited data regarding high-sensitivity troponin T in pediatric populations and its clinical interpretation. We sought to determine how high-sensitivity troponin values are associated with myocarditis diagnosis. High sensitivity troponin levels were reviewed for pediatric patients at our center from February 2022 to February 2023. Basic demographic and presenting data (including age, gender, body mass index), and diagnoses (cardiac diagnosis, including myocarditis, vs non-cardiac) were compared for patients with elevated initial troponin levels (≥ 12 ng/L) vs. those with non-elevated values. Of the 308 patients included, 91 (29.5%) had elevated hs-cTnT and 45 (14.6%) had a cardiac diagnosis, of whom 8 (2.5%) were ultimately diagnosed with acute myocarditis. There was no meaningful difference in demographic characteristics between the elevated and non-elevated hs-cTnT groups. For patients with diagnosis of myocarditis (n = 8), median peak levels were 506.5 ng/L (182.0 to 1184.0) versus 6.0 ng/L (< 6.0 to 13.5) for those with all other diagnoses (n = 300) (p < 0.001). A high sensitivity troponin cut-off value of 90 ng/dL was established for diagnosis of myocarditis, providing high sensitivity (100%) and specificity of (95%).
