Abstract

Aims The impact of some risk factors for stroke and bleeding, and the value of stroke and bleeding risk scores, in atrial fibrillation (AF), has been debated, as clinical trial cohorts have not adequately tested these. Our objective was to investigate risk factors for stroke and bleeding in AF, and application of the new CHA(2)DS(2)-VASc and HAS-BLED schemes for stroke and bleeding risk assessments, respectively. Methods and results We used the Swedish Atrial Fibrillation cohort study, a nationwide cohort study of 182 678 subjects with a diagnosis of AF at any Swedish hospital between 1 July 2005 and 31 December 2008, who were prospectively followed for an average of 1.5 years (260 000 years at risk). With the use of the National Swedish Drug Registry, all patients who used an oral anticoagulant anytime during follow-up were identified. Most of the analyses were made on a subset of 90 490 patients who never used anticoagulants. Risk factors for stroke, the composite thromboembolism endpoint (stroke, TIA, or systemic embolism), and bleeding, and the performance of published stroke and bleeding risk stratification schemes were investigated. On multivariable analysis, significant associations were found between the following 'new' risk factors and thromboembolic events; peripheral artery disease [hazard ratio (HR) 1.22 (95% CI 1.12-1.32)], 'vascular disease' [HR 1.14 (1.06-1.23)], prior myocardial infarction [HR 1.09 (1.03-1.15)], and female gender [HR 1.17 (1.11-1.22)].

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.
