Abstract

Context: Subclinical hypothyroidism has been associated with increased risk of coronary heart disease (CHD), particularly with thyrotropin levels of 10.0 mIU/L or greater. The measurement of thyroid antibodies helps predict the progression to overt hypothyroidism, but it is unclear whether thyroid autoimmunity independently affects CHD risk. Objective: The objective of the study was to compare the CHD risk of subclinical hypothyroidism with and without thyroid peroxidase antibodies (TPOAbs). Data Sources and Study Selection: A MEDLINE and EMBASE search from 1950 to 2011 was conducted for prospective cohorts, reporting baseline thyroid function, antibodies, and CHD outcomes. Data Extraction: Individual data of 38 274 participants from six cohorts for CHD mortality followed up for 460 333 person-years and 33 394 participants from four cohorts for CHD events. Data Synthesis: Among 38 274 adults (median age 55 y, 63% women), 1691 (4.4%) had subclinical hypothyroidism, of whom 775 (45.8%) had positive TPOAbs. During follow-up, 1436 participants died of CHD and 3285 had CHD events. Compared with euthyroid individuals, age- and gender-adjusted risks of CHD mortality in subclinical hypothyroidism were similar among individuals with and without TPOAbs [hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.87–1.53 vs HR 1.26, CI 1.01–1.58, P for interaction = .62], as were risks of CHD events (HR 1.16, CI 0.87–1.56 vs HR 1.26, CI 1.02–1.56, P for interaction = .65). Risks of CHD mortality and events increased with higher thyrotropin, but within each stratum, risks did not differ by TPOAb status. Conclusions: CHD risk associated with subclinical hypothyroidism did not differ by TPOAb status, suggesting that biomarkers of thyroid autoimmunity do not add independent prognostic information for CHD outcomes.

  • Recent evidence suggests that mild hyperthyroidism or hypothyroidism may increase overall and cardiovascular-specific mortality and morbidity.

    “However, recent evidence suggests that mild hyperthyroidism or hypothyroidism may increase overall and cardiovascular-specific mortality and morbidity (213)(214)(215)(216)(217)(218).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [215]

    The introduction (p. 2) reports an association between subclinical hypothyroidism and coronary heart disease mortality and events, and the Results (p. 4) examine those outcomes. The paper does not establish the broader claim about mild hyperthyroidism or overall mortality; its reported outcomes here are coronary heart disease-specific. (LLM, conf=0.88)

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.
