[Changes and clinical significance of serum thyroxine level in patients with congestive heart failure].
In order to explore the relationship between congestive heart failure (CHF) and serum thyroxine, we assayed serum thyroxine level in 52 patients with CHF and 28 normal persons by means of radioimmunoassay (RIA). The results showed that triiodothyronine reduced and reverse triiodothyronine elevated significantly in the patients compared with the normal (P < 0.05). The more severe heart failure developed, the more obvious changes of the hormones were observed. The results suggest that the alterations of serum thyroid level may be used as an index of the severity of heart failure.
