Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention for Multivessel Coronary Artery Disease: A One-Stage Meta-Analysis

Background and Aims: Data are emerging on 10-year mortality comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with stenting for multivessel disease (MVD) without left main (LM) involvement. We conducted an updated two-stage meta-analysis using reconstructed individual patient data to compare long-term mortality between CABG and PCI for patients with MVD without significant LM coronary disease.& nbsp;Methods: Medline and Embase databases were searched for articles comparing CABG with PCI for MVD. A two-stage meta-analysis was conducted using reconstructed patient level survival data for all-cause mortality with subgroups by SYNTAX score. The shared-frailty and stratified Cox models were fitted to compare survival endpoints.& nbsp;Results: We screened 1,496 studies and included six randomized controlled trials with 7,181 patients. PCI was associated with greater 10-year all-cause mortality risk (HR: 1.282, CI: 1.118-1.469, p < 0.001) compared with CABG. In patients with low SYNTAX score, 10-year all-cause mortality after PCI was comparable to CABG (HR: 1.102, 0.822-1.479, p = 0.516). However, in patients with moderate to high SYNTAX score, 10-year all-cause mortality was significantly higher after PCI compared with CABG (HR: 1.444, 1.122-1.858, p < 0.001; HR: 1.856, 1.380-2.497, p < 0.001, respectively).& nbsp;Conclusion: This updated reconstructed individual patient-data meta-analysis revealed a sustained lower cumulative all-cause mortality of CABG over PCI for multivessel disease without LM involvement.

Automated summary

This study conducted a two-stage meta-analysis using reconstructed individual patient data to compare long-term mortality between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for patients with multivessel disease (MVD) without left main (LM) involvement. The results showed that CABG had a lower cumulative all-cause mortality compared to PCI for MVD patients without LM involvement. However, in patients with moderate to high SYNTAX score, PCI had a significantly higher 10-year all-cause mortality compared to CABG.
