What does this research mean for the field?

Elderly women undergoing coronary artery bypass grafting have more preoperative comorbidities and a higher risk of postoperative major complications compared to men, despite no gender difference in the incidence of postoperative atrial fibrillation. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate sex-related differences in preoperative risk factors, hospital outcomes, length of stay, and postoperative atrial fibrillation among elderly patients undergoing isolated coronary artery bypass grafting.

Implication

Elevated complication risk in elderly women after CABG warrants caution; leaves open whether sex-specific strategies improve outcomes.

Key Points

To evaluate sex-related differences in preoperative risk factors, hospital outcomes, length of stay, and postoperative atrial fibrillation among elderly patients undergoing isolated coronary artery bypass grafting.
Prospective observational study analyzing 621 consecutive patients aged ≥65 years (401 men, 220 women) undergoing isolated coronary artery bypass grafting between May 1999 and November 2000 at Tampere University Hospital.
Assessed clinical baseline characteristics, postoperative complications, atrial fibrillation occurrence, length of stay, and 30-day mortality using logistic regression to identify independent predictors.
Postoperative atrial fibrillation rates did not differ between sexes, but women had significantly higher rates of stroke (6% vs. 3%, p=0.028), major complications (29% vs. 19%, p=0.004), and longer hospital stays (19 vs. 15 days, p<0.001).
Thirty-day mortality was 8% in women compared to 5% in men (p=0.06), with female sex conferring a 1.6-fold increased risk of major postoperative complications after adjusting for baseline covariates.
Age and number of anastomoses independently predicted postoperative atrial fibrillation in men, whereas no independent predictors were identified for women.

Structured PICO

Do clinical outcomes and the incidence of postoperative atrial fibrillation differ between elderly women and men undergoing isolated CABG?

Population

621 patients aged 65 years and older undergoing isolated coronary artery bypass grafting (CABG)

Intervention

Female gender

Comparator

Male gender

Outcome

Hospital events, especially postoperative atrial fibrillation (AF), and length of stayhard clinical

Elderly women undergoing CABG present with more comorbidities and have a higher risk of postoperative major complications compared to men, although the incidence of postoperative atrial fibrillation is similar between genders.
