Abstract
Background
Several randomized controlled trials (RCT) have reported no difference in long-term mortality between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI). The purpose of this pooled observational analysis was to compare recent retrospective studies examining long-term survival of patients with multi-vessel coronary artery disease undergoing CABG and PCI.
Methodology
We searched Medline for observational studies comparing long-term (>1 year) survival between CABG and PCI for the treatment of multi-vessel coronary artery disease over the past 10 years.
Results
Eight studies met inclusion criteria. A total of 306,868 patients (155,502 CABG; 151,366 PCI) were identified. Follow-up ranged from 1 to 8 years. Mantel-Haenszel combined hazard ratios (HR) for mortality demonstrated a protective benefit of CABG compared with PCI (HR=0.77, 95%CI=0.75–0.79).
Conclusion
These findings suggest a long-term survival advantage for CABG compared with PCI in patients with multi-vessel coronary artery disease.
