Drug-eluting versus bare-metal stents in unprotected left main coronary artery stenosis a meta-analysis.

Objectives: We undertook a meta-analysis to assess outcomes for drug-eluting stents (DES) and bare-metal stents (BMS) in percutaneous coronary intervention for unprotected left main coronary artery (ULMCA) stenosis.

Background: Uncertainty exists regarding the relative performance of DES versus BMS in percutaneous coronary intervention for unprotected left main coronary stenosis.

Methods: Of a total of 838 studies, 44 met inclusion criteria (n = 10,342).
