Key result
Postoperative atrial fibrillation after cardiac surgery was associated with significantly higher rates of complications, including renal failure, stroke, and myocardial infarction (P < 0.001).
Why the study?
Does the development of postoperative atrial fibrillation worsen clinical outcomes and survival in patients undergoing cardiac surgery?
Cohort (n=17,379)
No

p-value: p=< 0.001
Postoperative atrial fibrillation following cardiac surgery is associated with significantly increased risks of short- and long-term mortality and severe complications like stroke and myocardial infarction.

Postoperative AF signals higher complication risk after cardiac surgery; extends observational links but leaves causality and prevention impact open for RCTs.
Attaran et al. (2011) conducted a cohort in Postcardiac surgery (n=17,379). Postoperative atrial fibrillation vs. Maintenance of sinus rhythm (no postoperative atrial fibrillation) was evaluated on Postoperative complications, in-hospital mortality, and mid- to long-term survival rates (p=< 0.001). Postoperative atrial fibrillation after cardiac surgery was associated with significantly higher rates of complications, including renal failure, stroke, and myocardial infarction (P < 0.001).
