The abnormal changes of thyroid hormone and troponin I in congestive heart failure

Objective To investigate the changes of thyroid hormone and troponin I(cTnI) in congestive heart failure.Methods 60 CHF patients were divided into three groups according to the degree of heart failure. Serum levels of T3 and cTnI were measured by chemical fluorescence immunosorbantassay.Results In CHF patients, the level of serum T 3 were lower than control group. The level of cTnI increased markedly in CHF patients (P0.01) .In severe patients with wevere CHF, the change of T 3 and cTnI were bigger than the mild patients. There were a great change among different degree of CHF (P0.05) . After CHF improvement, serum T 3 incresed and serum cTnI decreased signifacantly (P0.01).Conclusion The change of serum Ts and cTnI in CHF has close correlation with the degree of CHF; the level of serum T 3 is negatively correlated with that of cTnI.
