Abstract

Objectives This study sought to identify whether obesity and obstructive sleep apnea (OSA) independently predict incident atrial fibrillation/flutter (AF).Background Obesity is a risk factor for AF, and OSA is highly prevalent in obesity. Obstructive sleep apnea is associated with AF, but it is unknown whether OSA predicts new-onset AF independently of obesity.Methods We conducted a retrospective cohort study of 3,542 Olmsted County adults without past or current AF who were referred for an initial diagnostic polysomnogram from 1987 to 2003. New-onset AF was assessed and confirmed by electrocardiography during a mean follow-up of 4.7 years.Results Incident AF occurred in 133 subjects (cumulative probability 14%, 95% confidence interval [CI] 9% to 19%). Univariate predictors of AF were age, male gender, hypertension, coronary artery disease, heart failure, smoking, body mass index, OSA (hazard ratio 2.18, 95% CI 1.34 to 3.54) and multiple measures of OSA severity. In subjects <65 years old, independent predictors of incident AF were age, male gender, coronary artery disease, body mass index (per 1 kg/m2, hazard ratio 1.07, 95% CI 1.05 to 1.10), and the decrease in nocturnal oxygen saturation (per 0.5 U log change, hazard ratio 3.29, 95% CI 1.35 to 8.04). Heart failure, but neither obesity nor OSA, predicted incident AF in subjects > or =65 years of age.Conclusions Obesity and the magnitude of nocturnal oxygen desaturation, which is an important pathophysiological consequence of OSA, are independent risk factors for incident AF in individuals <65 years of age.

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

  • An agent that raises the arousal threshold may cause substantial hypoxemia and hypercapnia that could affect end organ function.

    “an agent which raises the arousal threshold may yield substantial hypoxemia and hypercapnia which could impact end organ function.”

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [414]

    The Discussion says apnea causes hypoxemia that may contribute to cardiovascular complications. It does not address whether an agent that raises the arousal threshold causes substantial hypoxemia or hypercapnia; searches for those terms found no supporting passage. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In one retrospective PSG cohort, patients with AHI ≥5 were twice as likely to develop atrial fibrillation as those with AHI <5, an effect limited to those under age 65; after adjustment, mean nocturnal SaO2 but not AHI was an independent predictor of incident atrial fibrillation.

    “In one, patients with AHI ≥ 5 were twice as likely to develop AF as those with AHI < 5, an effect that was limited to those under age 65; however, adjusting for age, sex, BMI, and prevalent CV disease, mean nocturnal SaO2 but not AHI was an independent predictor of incident AF.414”

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.
