Evaluation of serum cardiac troponin I values in children less than 1 year of age.

OBJECTIVE The objective is to verify the cardiac troponin I values in children less than 1 year of age without clinical cardiac dysfunction. METHODS The cardiac troponin I values were determined in 99 children less than 1 year of age, including term infants without diseases related to cardiac dysfunction using the specific kit Opus T Troponin I (cTn) (Dade Behring Inc. -Newalk, DE 19714, USA). RESULTS All children have values of cardiac troponin I less than 0.1 ng/ml. CONCLUSION We verified that the cardiac troponin I value is less than 0.1 ng/ml in children less than 1 year, including term infants without cardiac dysfunction, when analized by the kit Opus T Troponin I (cTn) test modules.
