Off-pump versus on-pump coronary artery bypass surgery in patients aged 80 years and older: institutional results and meta-analysis.
Patients aged ≥80 years are at high risk of adverse events after coronary artery bypass grafting. This study was performed to evaluate whether off-pump coronary artery bypass surgery (OPCAB) is superior to conventional surgery (CCAB) in these high-risk patients. The outcome of 185 patients aged ≥80 years who underwent OPCAB or CCAB at our institution was reviewed and a meta-analysis on this issue was performed. ⋯ At 2 years, survival was 82.8% (95% CI 76.4-89.2) after CCAB and 88.3% (95% CI 82.9-93.7) after OPCAB. Current results indicate that OPCAB compared with CCAB in patients aged ≥80 years is associated with significantly lower postoperative stroke and with a trend toward better early survival. However, suboptimal quality of the available studies, particularly the lack of comparability of the study groups, prevents conclusive results on this controversial issue.
