Adjunctive Bare-Metal Stenting Associated With Improved Outcomes in Patients With Multivessel Disease Treated With Drug-Eluting Stents.

Background: The use of both bare-metal stents (BMSs) and drug-eluting stents (DESs) in the setting of multivessel percutaneous coronary intervention (PCI) continues because of cost considerations.

Methods: A retrospective analysis of patients with ≥ 2 coronary arteries with angiographic stenoses of ≥ 70% severity who were treated with multivessel PCI and ≥ 2 stents between April 2007 and March 2011 was performed using a prospective single-centre PCI registry. Follow-up data were obtained from the Discharge Abstract Database of the Canadian Institute for Health Information and the Registered Persons Database.

Association between drug-eluting stent type and clinical outcomes in patients with chronic kidney disease undergoing percutaneous coronary intervention.

Background: The comparative efficacy of first- vs second-generation drug-eluting stents (DESs) in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI) is unknown.

Methods: A retrospective analysis of consecutive patients undergoing PCI at a tertiary PCI center from 2007-2011 was performed, with linkage to administrative databases for long-term outcomes. CKD was defined as creatinine clearance (CrCl) < 60 mL/min.
