Abstract

AIMS: We tested apnoea/hypopnoea index (AHI), high-sensitivity (hs) C-reactive protein and clinical/instrumental variables as predictors of atrial fibrillation (AF) recurrence over 1-year follow-up after successful electrical cardioversion. METHODS AND RESULTS: We enrolled 158 consecutive patients. Apnoea/hypopnoea index was assessed with standard overnight polysomnography and hs-C-reactive protein with immunonephelometry assay the day before electrical cardioversion. Atrial fibrillation recurrences occurred in 81 patients (51%). Predictors at univariate analysis were: AHI > or = 15 events/h (P = 0.001), hs-C-reactive protein >0.30 mg/dL (P = 0.009), AF duration >3 days (P = 0.008), diabetes (P = 0.03), and ongoing anti-arrhythmic therapy at the time of electrical cardioversion (P = 0.03). Survival analysis confirmed that patients with AHI > or = 15 events/h and hs-C-reactive protein > 0.30 mg/dL had a higher recurrence rate of AF (log rank P = 0.0006 and P = 0.01, respectively). Predictors at multivariate analysis were: AHI > or = 15 events/h (P = 0.003), hs-C-reactive protein > 0.30 mg/dL (P = 0.01) and ongoing anti-arrhythmic therapy (P = 0.04). A predictive model based upon the multiple effects of significant variables plus age as a continuous variable stratified the risk of AF recurrence, more than tripled with all dichotomized variables altered with respect to normal variables (85 vs. 27%). CONCLUSION: AHI > or = 15 events/h and hs-C-reactive protein > 0.30 mg/dL are the strongest predictors of the predictors chosen of AF recurrence after successful electrical cardioversion over 1-year follow-up.

  • Moderate or severe OSA (AHI ≥15) is reported in 20%-62% of atrial fibrillation patients.

    From International Consensus Statement on Obstructive Sleep Apnea (2023) · cites this paper as [714]

    The ‘Sleep apnoea syndrome and risk of atrial fibrillation’ section reports moderate-to-severe sleep apnoea in 31% of 158 AF patients after successful cardioversion. That supports a prevalence within the cited range, but this paper does not establish the 20%–62% range or its endpoints. (LLM, conf=0.86)

  • In six studies that systematically assessed OSA before atrial fibrillation treatment, OSA was associated with an approximately two- to three-fold increased risk of recurrent atrial fibrillation following electrical cardioversion or pulmonary vein isolation.

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.
