Key result
Previous smoking was associated with increased late mortality compared with never smoking after concomitant AVR-CABG surgery (HR 1.44; 95% CI 1.14-1.81; p=0.002).
Why the study?
Does smoking status impact short-term complications and long-term mortality in patients undergoing concomitant AVR-CABG surgery?
Population
2,558 patients undergoing concomitant aortic valve replacement and coronary artery bypass graft surgery
Comparison
Current or previous smoking status vs Nonsmokers
Design
Cohort
Follow-up
mean 36 months (range, 0-105 months)

Previous smoking history signals higher late mortality after AVR-CABG; leaves open whether cessation interventions improve survival in prospective studies.
Cohort (n=2,558)
Yes
Does smoking status impact short-term complications and long-term mortality in patients undergoing concomitant AVR-CABG surgery?
Hazard Ratio: 1.44 (95% CI 1.14–1.81)
p-value: p=0.002
Smoking status does not significantly impact short-term perioperative outcomes after concomitant AVR-CABG, but previous smoking is associated with increased late mortality.
Saxena et al. (2013) conducted a cohort in Concomitant aortic valve replacement and coronary artery bypass graft (AVR-CABG) surgery (n=2,558). Smoking status (previous or current smoking) vs. Nonsmokers was evaluated on Late mortality (HR 1.44, 95% CI 1.14-1.81, p=0.002). Previous smoking was associated with increased late mortality compared with never smoking after concomitant AVR-CABG surgery (HR 1.44; 95% CI 1.14-1.81; p=0.002).
