Abstract

OBJECTIVE: This study investigated whether changes in thyroid hormone (TH) in plasma are associated with the recovery of cardiac function in patients with acute myocardial infarction (AMI). Previous experimental studies have provided evidence of potential implication of TH signaling in post-ischemic recovery of cardiac function. METHODS: A total of 47 patients with AMI and early reperfusion therapy were included in this study. Myocardial injury was analyzed by peak creatinine kinase-MB (CKMB) and cardiac function was assessed by echocardiographic left ventricular ejection fraction (LVEF%). Recovery of function (ΔEF%) was estimated as the difference of LVEF% between 48 h and 6 months (6 mo) after AMI. Total triiodothyronine (T(3)), thyroxine (T(4)), and TSH were measured in plasma at different time points (24 h, 48 h, 5 d, and 6 mo). RESULTS: A significant correlation between LVEF% and T(3) (r=0.5, P=0.0004) was found early after AMI (48 h), whereas no correlation was observed between CKMB and T(3) (r=-0.04, P=0.81). A strong correlation was found between ΔEF% and total T(3) (r=0.64, P=10(-6)) at 6 mo after AMI. Furthermore, multivariate regression analysis revealed that T(3) at 6 mo (r=0.64, r(2)=0.41, P=10(-6)) was an independent determinant of ΔEF%. CONCLUSION: Changes in T(3) levels in plasma are closely correlated with the early and late recovery of cardiac function after AMI. T(3) levels at 6 mo appear to be an independent predictor of late functional recovery.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • T3 at 6 months was an independent predictor of changes in left ventricular ejection fraction between the early and follow-up periods.

    “T 3 at 6 months was an independent predictor of LV ejection fraction changes between the early and follow-up periods (123).”

  • Lower T3 levels after acute myocardial infarction independently predict late recovery of left ventricular function after 6 months.

    “lower T 3 levels after AMI are an independent predictor of late recovery of LV function after 6 months (123).”

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.
