Percutaneous coronary intervention for left main stem disease: Impact of diabetes mellitus on mortality.

Objectives: We assessed the impact of diabetes mellitus (DM) on mortality after percutaneous coronary intervention (PCI) for left main stem (LMS) disease. Second, we compared mortality outcomes between non-insulin treated (NITDM) and insulin treated diabetes (ITDM) in different clinical settings.

Background: There is a paucity of "real world" outcomes data in diabetic patients undergoing LMS PCI.
