This network meta-analysis compared conventional aortocoronary and composite grafting strategies in coronary artery bypass surgery. It included 24 studies—8 randomised trials and 16 observational studies—with 9692 patients; the primary outcome was in-hospital or 30-day all-cause mortality. Mortality did not differ between strategies (P = 0.387). The analysis also found no statistically significant differences in stroke, myocardial infarction, reoperation for bleeding, postoperative atrial fibrillation, or deep sternal wound infection. The authors concluded that composite grafting can be performed as safely as conventional aortocoronary CABG.
Key findings
- In-hospital or 30-day all-cause mortality did not differ between conventional aortocoronary and composite grafting (P = 0.387).
- No differences were detected in stroke (P = 0.277), myocardial infarction (P = 0.09), reoperation for bleeding (P = 0.500), postoperative atrial fibrillation (P = 0.219), or deep sternal wound infection (P = 0.549).
- The network meta-analysis included 24 studies (8 RCTs and 16 observational studies), comprising 9692 patients.
Why it matters
Composite grafting can avoid aortic anastomoses and may reduce aortic manipulation, but its safety relative to conventional grafting is an important consideration. Across the included studies, early mortality and several postoperative complications did not differ detectably between strategies, providing comparative evidence to inform assessment of these approaches.
What to keep in mind
The analysis combined randomised and observational studies, and its primary outcome was limited to in-hospital or 30-day mortality; the abstract does not report longer-term outcomes.
