OBJECTIVES: This study sought to compare the efficacy of coronary artery bypass graft surgery (CABG) to that of percutaneous coronary intervention (PCI) with first-generation drug-eluting stents among patients with multivessel disease (MVD), unprotected left main (LM) disease, and single-vessel proximal left anterior descending (LAD) disease.

BACKGROUND: The efficacy and safety of CABG versus PCI with drug-eluting stents in patient subgroups remains controversial.

METHODS: We systematically searched Cardiosource, Circulation, Clinicaltrials.gov, the Cochrane Library, EMBASE, and Medline for articles published through June 2013 for randomized controlled trials comparing CABG with PCI. Primary endpoints included mortality, myocardial infarction, revascularization, and stroke. Data were meta-analyzed with random-effects models.

RESULTS: We identified 7 randomized controlled trials (N = 5,835): 2 of MVD (n = 2,410, 100% diabetic), 2 of LM disease (n = 1,206, 29.0% diabetic), 1 of 3-vessel or LM disease (n = 1,900, 25.5% diabetic), and 2 of single-vessel proximal LAD disease (n = 319, 36.3% diabetic). In MVD patients, CABG reduced the risk of mortality (risk ratio [RR]: 0.70, 95% confidence interval [CI]: 0.57 to 0.87), myocardial infarction (RR: 0.47, 95% CI: 0.36 to 0.61), and repeat revascularization (RR: 0.36, 95% CI: 0.24 to 0.52), but increased stroke risk (RR: 1.72, 95% CI: 1.02 to 2.90). In patients with LM disease, CABG reduced revascularization risk (RR: 0.60, 95% CI: 0.46 to 0.78) and increased stroke risk (RR: 2.89, 95% CI: 1.15 to 7.27). Data for patients with single-vessel proximal LAD disease were inconclusive.

CONCLUSIONS: CABG is more efficacious than is PCI with first-generation drug-eluting stents in patients with LM and MVD, at the cost of increased rates of stroke. No conclusion can be drawn for patients with single-vessel proximal LAD disease.
