Usefulness of serum triiodothyronine (T3) to predict outcomes in patients hospitalized with acute heart failure
Abstract
Thyroid hormone plays an important role in cardiac function. Low levels of serum triiodothyronine (T 3) due to nonthyroidal illness syndrome may have adverse effects in heart failure (HF). This study was designed to assess the ability of T 3 to predict in-hospital outcomes in patients with acute HF. In total, 137 patients without thyroid disease or treatment with drugs which affect TH levels, who were hospitalized with acute HF were prospectively enrolled and studied. TH levels were tested upon hospital admission, and outcomes were compared between patients with low (<2.3 pg/ml) and normal (≥2.3 pg/ml) free T 3 levels as well as between those with low (<0.6 ng/ml) and normal (≥0.6 ng/ml) total T 3 levels. Low free T 3 correlated with an increased length of stay in the hospital (median 11 vs 7 days, p <0.001) and higher rates of intensive care unit admission (31.8% vs 16.9%, p = 0.047), with a trend toward increased need for invasive mechanical ventilation (9.0% vs 1.4%, p = 0.056). Low total T3 correlated with an increased length of stay in the hospital (median 11 vs 7 days, p <0.001) and increased need for invasive mechanical ventilation (9.8% vs 1.3%, p = 0.045). In conclusion, low T 3 predicts worse hospital outcomes in patients with acute HF and can be useful in the risk stratification of these patients.

Thyroid hormone metabolism alterations are associated with worse prognosis in patients with ischemic and nonischemic left ventricular dysfunction in both acute decompensated and chronic stable heart failure.
“Furthermore, in addition to conventional risk factors, TH metabolism alterations have been associated with a worse prognosis in patients with both ischemic and nonischemic LV dysfunction in both acute decompensated and chronic stable HF (131-133).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
