Meta-analysis of Four Randomized Controlled Trials on Long-Term Outcomes of Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention With Stenting for Multivessel Coronary Artery Disease

To provide a quantitative analysis of long-term clinical outcomes, a meta-analysis of 4 randomized controlled trials of percutaneous coronary intervention (PCI) with stenting versus coronary artery bypass grafting (CABG) for multivessel coronary artery disease was conducted. The search identified 4 randomized controlled trials of PCI with stenting versus CABG that enrolled patients with multivessel coronary artery disease. In conclusion, pooled analysis demonstrated no statistically significant differences in death, cardiac death, Q-wave myocardial infarction, cerebrovascular accidents, and angina pectoris between PCI with stenting and CABG. However, PCI with stenting was associated with a statistically significant increase in subsequent PCI, subsequent CABG, subsequent revascularization (PCI or CABG), and major adverse cardiovascular events relative to CABG.
