Background: We assessed predictors of long-term outcomes after coronary artery bypass grafting (CABG) versus those after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in 3,230 patients with left main or multivessel coronary artery disease (CAD). Methods and Results: Data were pooled from the BEST, PRECOMBAT, and SYNTAX trials. Age, chronic kidney disease, chronic obstructive lung disease, left ventricular dysfunction, and peripheral arterial disease (PAD) were common predictors of all-cause mortality. Diabetes mellitus, previous myocardial infarction (MI), and SYNTAX score were independent predictors of all-cause mortality in the PCI group, but not in the CABG group. In the CABG group, age was the only risk factor for MI; left ventricular dysfunction, hypertension, and PAD were risk factors for stroke. On the other hand, in the PCI group, incomplete revascularization and previous MI were risk factors for MI; age and previous stroke for stroke. In addition, chronic kidney disease significantly correlated with a composite outcome of death, MI, or stroke in the CABG group, and incomplete revascularization and previous MI in the PCI group. Conclusions: Simple clinical variables and SYNTAX score differentially predict long-term outcomes after CABG versus those after PCI with DES for left main or multivessel CAD. Those predictors might help to guide the choice of revascularization strategy.
