title: Developing thyroid disorders is associated with poor prognosis factors in patient with stable chronic heart failure.
abstract: We sought to assess the developing of thyroid disorders in forty eight patients with chronic stable heart failure and without thyroid abnormalities during six months follow-up. Thyroid function disorders were observed in 27.1% of the subjects: sick euthyroid syndrome (12.5%), subclinical hypothyroidism (10.4%) and overt hypothyroidism (6.2%). Subjects with higher thyroid stimulating hormone (TSH) levels at the end of the study had more hospitalizations. The developing of altered thyroid profile was related to lower hemoglobin levels, smaller phase angle with bioelectrical impedance method and more fatigue perception by the patients. This abnormal thyroid function behavior on stable chronic heart failure and was observed as part of the disease progress and was associated to worse prognosis factors as lower phase angle and anemia.
