Thyroid Disorders and Prognosis in Chronic Heart Failure: A Long-Term Follow-Up Study

Abstract

Hypo is associated with a worse prognosis over a long-term follow-up. The association with heart failure hospitalization is not dependent on the baseline TSH levels, whereas the association with death is significant only when TSH >10 mIU/L. Finally, Hyper does not have any association with a worse prognosis.
