Background Several studies have compared the treatment effectsof coronary stenting and coronary-artery bypass grafting (CABG).However, there are limited data regarding the long-term outcomesof these two interventions for patients with unprotected leftmain coronary artery disease.
Methods We evaluated 1102 patients with unprotected left maincoronary artery disease who underwent stent implantation and1138 patients who underwent CABG in Korea between January 2000and June 2006. We compared adverse outcomes (death; a compositeoutcome of death, Q-wave myocardial infarction, or stroke; andtarget-vessel revascularization) with the use of propensity-scorematching in the overall cohort and in separate subgroups accordingto type of stent.
Results In the overall matched cohort, there was no significantdifference between the stenting and CABG groups in the riskof death (hazard ratio for the stenting group, 1.18; 95% confidenceinterval [CI], 0.77 to 1.80) or the risk of the composite outcome(hazard ratio for the stenting group, 1.10; 95% CI, 0.75 to1.62). The rates of target-vessel revascularization were significantlyhigher in the group that received stents than in the group thatunderwent CABG (hazard ratio, 4.76; 95% CI, 2.80 to 8.11). Comparisonsof the group that received bare-metal stents with the groupthat underwent CABG and of the group that received drug-elutingstents with the group that underwent CABG produced similar results,although there was a trend toward higher rates of death andthe composite end point in the group that received drug-elutingstents.
Conclusions In a cohort of patients with unprotected left maincoronary artery disease, we found no significant differencein rates of death or of the composite end point of death, Q-wavemyocardial infarction, or stroke between patients receivingstents and those undergoing CABG. However, stenting, even withdrug-eluting stents, was associated with higher rates of target-vesselrevascularization than was CABG.
