Increased circulating High-Sensitivity Troponin T concentrations in children and adolescents with obesity and the metabolic syndrome: A marker for early cardiac damage?
چکیده انگلیسی

ObjectiveChildhood obesity is associated with an increased risk for atherosclerosis mediated by the pathogenetic mechanisms that lead to the development of the Metabolic Syndrome (MetS). High-Sensitivity Troponin T (hs-TnT) is a specific marker of ischemic myocardial damage, whereas a minimal elevation of this biomarker has been found in adults with a high-risk for cardiovascular disease. We hypothesized that hs-TnT might be altered in obese children with and/or without the Mets.Materials and MethodsFifty-seven (34 males) obese and 25 non-obese (6 males) children were assessed at the Childhood Obesity Clinic of our department. Obesity was defined using the IOTF criteria. Metabolic syndrome was defined with the IDF criteria. Hs-TnT was measured using an electrochemiluminescence-based assay.ResultsThe entire group of obese children had significantly higher hs-TnT concentrations [4.1 ± 3.4 ng/L] (p=0.029) than the non-obese ones [3.0 ± 0.2 ng/L), however, in both groups the levels of the cardiac biomarker were within the normal range. Comparison of the obese children with or without the MetS and the non-obese, revealed that those with the MetS had significantly higher hs-TnT (6.7±7.1 ng/L) than the obese without MetS (3.7 ± 2.1 ng/L) [p=0.044], and the non-obese [p=0.014]. Hs-TnT did not differ between the obese without MetS and the non-obese.ConclusionsCirculating concentrations of hs-TnT in obese children with the MetS are higher than those of the obese without the MetS and the non-obese, suggesting that it is obesity-related metabolic changes rather than obesity per se linked to increased hs-TnT in children.
