Abstract

Background and Purpose—: Fibroblast growth factor 23 (FGF23) is a hormone that regulates phosphorus and vitamin D metabolism. Elevated FGF23 concentrations are associated with excess risk of cardiovascular disease. Associations of FGF23 with stroke outcomes are less clear. Methods—: Using a case–cohort study design, we examined the association of baseline plasma FGF23 concentrations with incident stroke in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, a cohort of black and white adults aged ≥45 years. FGF23 was measured in 615 participants who developed incident stroke (cases) and in 936 participants randomly selected from the REGARDS cohort (comparison subcohort). Results—: In multivariable-adjusted models, higher calcium and phosphorus concentrations, lower estimated glomerular filtration rate and higher urine albumin excretion were independently associated with higher FGF23. There was no statistically significant association of FGF23 with risk of all-cause stroke in Cox models adjusted for demographic factors and established stroke risk factors (hazard ratio comparing fourth with first quartile 1.19; 95% confidence interval, 0.78–1.82). In prespecified models stratified by stroke subtypes, there was a graded association of FGF23 with risk of cardioembolic stroke in fully adjusted models (quartile 1, reference; quartile 2 hazard ratio, 1.48; 95% confidence interval, 0.63–3.47; quartile 3 hazard ratio, 1.99; 95% confidence interval, 0.89–4.44; quartile 4 hazard ratio, 2.52; 95% confidence interval, 1.08–5.91). There were no statistically significant associations of FGF23 with other ischemic stroke subtypes or with hemorrhagic strokes. Conclusions—: Higher FGF23 concentrations were associated with higher risk of cardioembolic but not with other stroke subtypes in community-dwelling adults. Additional studies should delineate reasons for these findings.

  • In women aged <65 years with lone AF, the rate of thromboembolism varies widely, from 0.1-0.2% annual stroke risk in a Swedish study to 1.24/100 person-years in a Danish study.

    “Notably, a nationwide register study of >120,000 individuals with AF in Denmark found a rate of thromboembolism as high as 1.24/100 person–years among women aged < 65 years with lone AF at 1-year follow-up.86 In contrast, however, a Swedish nationwide study of >140,000 individuals with AF showed that the annual stroke risk for women with AF who were aged <65 years was 0.1–0.2%.85”

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.
