Key result
Preoperative AF shows no link to higher 30-day mortality in patients undergoing CABG.
Why the study?
Atrial fibrillation is considered a comorbid factor for coronary artery bypass surgery, but current literature regarding its effects remains limited.
Does preoperative atrial fibrillation worsen in-patient outcomes and 12-month survival in patients undergoing isolated coronary artery bypass grafting?
Cohort (n=151)
No
Does preoperative atrial fibrillation worsen in-patient outcomes and 12-month survival in patients undergoing isolated coronary artery bypass grafting?
Effect estimate: OR 0.98
Absolute Event Rate: 0% vs 2.3%
p-value: p=0.496
Preoperative atrial fibrillation in patients undergoing isolated CABG is associated with a higher rate of repeat revascularization at 12 months, but does not significantly impact 12-month overall survival or perioperative complications.
No takes yet. Share an insight, caveat, or question.
Preoperative AF may not increase short-term mortality after CABG; leaves open its association with 12-month revascularization.
Kaya et al. (2023) conducted a cohort in Ischemic heart disease requiring coronary artery bypass grafting (n=151). Preoperative atrial fibrillation vs. No preoperative atrial fibrillation was evaluated on 30-day mortality (OR 0.98, p=0.496). Preoperative atrial fibrillation in patients undergoing coronary artery bypass grafting did not significantly increase 30-day mortality (0.0% vs 2.3%, p=0.496) compared to patients without atrial fibrillation.
