BACKGROUNDBACKGROUND
Percutaneous coronary intervention Percutaneous coronary intervention (PCI) with drug-eluting stent (DES) (PCI) with drug-eluting stent (DES) implantation is increasingly used for implantation is increasingly used for unprotected left mainunprotected left main disease (ULM) disease (ULM)
Drug-eluting stent implantation Drug-eluting stent implantation favorably influences outcome in favorably influences outcome in diabetic patientsdiabetic patients with non-ULM with non-ULM
There are no data on the clinical There are no data on the clinical results of DES for ULM in diabetic results of DES for ULM in diabetic patientspatients
AIM OF THE STUDYAIM OF THE STUDY
We aimed to appraise the We aimed to appraise the outcomes of diabetics with outcomes of diabetics with unprotected left main disease unprotected left main disease (ULM) treated with drug-eluting (ULM) treated with drug-eluting stents (DES)stents (DES)
METHODSMETHODS
We abstracted baseline, procedural We abstracted baseline, procedural and follow-up data on all patients and follow-up data on all patients
undergoing PCI for undergoing PCI for ULMULM disease at disease at our Institution our Institution
treated with treated with DESDES since 2002 since 2002 andand identified 3 groups according to identified 3 groups according to
their their diabetic statusdiabetic status
END-POINTEND-POINT
We evaluate the rate of We evaluate the rate of major adverse major adverse cardiac eventscardiac events (MACE) defined as: (MACE) defined as:
cardiac death, cardiac death, myocardial infarction, myocardial infarction, or target vessel revascularizationor target vessel revascularization
Secondary end-points were individual Secondary end-points were individual MACE components and stent MACE components and stent thrombosis (according to ARC)thrombosis (according to ARC)
