Patients with postoperative atrial fibrillation have a doubled cardiovascular mortality
Open accessAbstract
OBJECTIVES: To investigate the impact of postoperative AF on late mortality and cause of death in CABG patients. DESIGN: All CABG patients without preoperative AF surgically treated between January 1, 1997 and June 30, 2000 were included (N = 1419). Altogether, 419 patients (29.5%) developed postoperative AF. After a median follow-up of 8.0 years, survival data were obtained, causes of death were compared and Cox proportional hazard analysis was used to determine predictors of late mortality. RESULTS: The total mortality was 140 deaths/419 patients (33.4%) in postoperative AF patients and 191 deaths/1 000 patients (19.1%) in patients without AF. Death due to cerebral ischemia (2.6% vs. 0.5%), myocardial infarction (7.4% vs. 3.0%), sudden death (2.6% vs. 0.9%), and heart failure (6.7% vs. 2.7%) was more common among postoperative AF patients. Postoperative AF was an age-independent risk indicator for late mortality with a hazard ratio (HR) of 1.56 (95% confidence interval 1.23-1.98). CONCLUSIONS: Postoperative AF is an age-independent risk factor for late mortality in CABG patients, explained by an increased risk of cardiovascular death.

In the long term, patients with an episode of postoperative AF have a twofold increase in cardiovascular mortality and a substantially increased risk of future AF and ischaemic stroke compared with patients that remain in sinus rhythm after surgery.

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.
