Abstract

Background: Although the heritability of atrial fibrillation/atrial flutter ( AF / AF l) has been determined, the familial risk in multiplex families is unclear. The main aim of this nationwide study was to determine the familial risk of AF / AF l in multiplex families. Methods and Results: We examined the familial risk of AF / AF l in the entire Swedish population. We linked Multigeneration Register data on individuals aged 0 to 76 years with Hospital Discharge Register data for 1987–2008 and Outpatient Register data for 2001–2008 to compare AF / AF l risk among relatives of all 300 586 individuals with AF / AF l with that among relatives of unaffected individuals. We used conditional logistic regression to investigate differences in exposure between cases and controls. Parents (odds ratio [ OR ] 1.95 [95% CI 1.89 to 2.00]) and siblings ( OR =3.08 [3.00 to 3.16]) of cases had higher odds of AF / AF l than did parents and siblings of controls. AF / AF l OR s were increased in both sexes. For 2% of cases, both parents had AF / AF l, compared with only 0.7% of controls ( OR =3.60 [3.30 to 3.92]). Moreover, 3% of cases had ≥2 siblings with AF / AF l, compared with 1% of controls ( OR =5.72 [5.28 to 6.19]). In premature cases (diagnosed at age <50 years), the OR s were 5.04 (4.36 to 5.82) and 8.51 (6.49 to 11.15) for AF / AF l in both parents and AF / AF l in ≥2 siblings, respectively. The overall spouse OR was 1.16 (1.13 to 1.19). Conclusions: Family history of AF / AF l increases the odds of AF / AF l in first‐degree relatives. High familial risks were observed in multiplex families.

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.
