Question clinique
Is mortality improved if patients with left main coronary artery disease are managed with coronary artery bypass grafting or with percutaneous interventions with drug-eluting stents?
L’Essentiel
The 5- and 10-year all-cause mortality rates are similar in persons with left main coronary artery disease whether managed with PCI with drug-eluting stents or with CABG. 1a

Sommaire
This team searched several databases and identified 4 randomized trials that compared percutaneous intervention (PCI; n = 2197) and coronary artery bypass grafting (CABG; n = 2197) in adults with left main coronary artery disease and reported 5-year mortality outcomes. The authors were able to obtain the data on the individual participants in these trials. Three of the trials recruited only persons with left main disease. Although the fourth trial included persons with multivessel disease, the authors were able to isolate the subgroups with left main disease. After 5 years, there was no significant difference in all-cause mortality between the 2 groups (slightly > 10%), and no significant difference in cardiovascular and noncardiovascular death. Additionally, the authors found no significant difference in 10-year mortality (slightly > 20%). However, the PCI-managed patients had slightly more spontaneous myocardial infarctions (6.2% vs 2.6%; number needed to treat to harm [NNTH] 31; 95% CI 23 - 47) and subsequent revascularizations (18.3% vs 10.7%; NNTH 14; 11 - 19).

no difference in 5-10 year survival between CABG and PCI with Stents
