Randomized Controlled Trial Multicenter Study Comparative Study
On-pump versus off-pump coronary artery bypass surgery: cost-effectiveness analysis alongside a multisite trial.
Questions have been raised about the costs and outcomes for patients receiving on-pump and off-pump coronary artery bypass graft surgery. As part of the Department of Veterans Affairs Randomized On/Off Bypass (ROOBY) multisite trial, a cost-effectiveness analysis was performed to compare on-pump versus off-pump patients' quality-adjusted life-years and costs at 1 year. ⋯ At 1 year, off-pump coronary artery bypass graft surgery was more expensive than on-pump when late off-pump-to-on-pump conversions were included. Excluding late conversions, there was no difference in quality-adjusted life-years or costs.

Review Meta Analysis Comparative Study
Association between obesity and postoperative atrial fibrillation in patients undergoing cardiac operations: a systematic review and meta-analysis.
In a systematic review and random-effects meta-analysis, we evaluated whether obesity is associated with postoperative atrial fibrillation (POAF) in patients undergoing cardiac operations. We selected 18 observational studies until December 2011 that excluded patients with preoperative AF (n=36,147). ⋯ The association between obesity and POAF did not vary substantially by type of cardiac operation, study design, or year of publication. POAF was significantly associated with a higher risk of stroke, respiratory failure, and operative death.
