OBJECTIVES: To compare the safety and efficacy of coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) using drug-eluting stents (DES) in patients with unprotected left main coronary artery (ULMCA) disease. METHODS: MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles were searched for clinical studies that reported outcomes at the 1-year follow-up after PCI with DES and CABG for the treatment of ULMCA stenosis. Sixteen studies (three randomized controlled trials and 13 observational studies) were identified and included a total of 5674 patients (2331 for PCI with DES and 3343 for CABG). RESULTS: At the 1-year follow-up, there was no significant difference between the CABG and DES groups in the risk for death (odds ratio [OR] 0.691, P = 0.051) or the composite endpoint of death, myocardial infarction or stroke (OR 0.832, P = 0.258). The risk for target vessel revascularization (TVR) was significantly higher in the PCI group compared with the CABG group (OR 3.597, P < 0.001). The risk of major adverse cardiac and cerebrovascular events (MACCE) was significantly higher in the PCI group compared with the CABG group (OR 1.607, P < 0.001). A publication bias was observed regarding the outcome of death and also a considerable heterogeneity effect on the composite endpoint of death, myocardial infarction or stroke and MACCE. CONCLUSIONS: CABG surgery remains the best option of treatment for patients with ULMCA disease, with less need of TVR and lower MACCE rates.
