Abstract

BackgroundData regarding the efficacy of percutaneous coronary intervention (PCI) with new-designed drug eluting stent (new-DES) vs. bare metal stent (BMS) of saphenous vein grafts (SVG) stenosis is scarce. The primary objective was to compare 1-year clinical outcomes of PCI in stenosis of SVG using new-DES vs. BMS in a real-world population.MethodsWe carried out a multi-center registry comparing new-DES with BMS in all consecutive patients undergoing PCI of SVG. The primary composite endpoint was major adverse cardiac and cerebrovascular events (MACCE) at 1 year. This observation included 792 consecutive patients (mean age: 69 ±8.9 years), treated with either new-DES (n = 379, 47.9%) or BMS (n = 413, 52.1%).ResultsIn unmatched cohort patients treated with new-DES vs. BMS had lower MACCE (28.3% vs. 21.4%, HR = 0.69, 95% CI: 0.50–0.95, p = 0.025) as well as myocardial infarctions (MI) (12.1% vs. 6.3%; HR = 0.49, 95% CI: 0.30–0.82, p = 0.005) at 1 year. After propensity score matching similar, significant reduction in MACCE and MI was sustained in new-DES vs. BMS groups (HR = 0.66, 95% CI: 0.46–0.96, p = 0.030; and HR = 0.53, 95% CI: 0.31–0.92, p = 0.020, respectively).ConclusionsIn patients undergoing PCI of SVG, the use of new-DES is associated with a reduced 1-year rate of MACCE and MI compared to BMS.
