AIMS: Studies demonstrate that percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is associated with reduced revascularization and major adverse cardiac events (MACE) rates compared to bare metal stents (BMS) in native coronary vessels. Optimal PCI treatment of saphenous vein graft (SVG) lesions remains unclear despite SVG procedures representing up to 10% of PCI cases. We therefore performed a meta-analysis to compare outcomes between BMS and DES in SVG PCI. METHODS AND RESULTS: A search (2004-2009) of MEDLINE and conference proceedings for all relevant studies comparing mortality and MACE outcomes in DES versus BMS in SVG PCI and meta-analysis of the data was performed. Twenty studies were identified from 2005 to 2009 enrolling a total of 5,296 patients. Meta-analysis revealed a decrease in mortality associated with DES use, odds ratio (OR) 0.68; 95% confidence interval (CI) 0.53-0.88; P = 0.004. Similarly, MACE (OR 0.64; 95% CI 0.51-0.82; P < 0.001), total lesion revascularization (OR 0.60; 95% CI 0.43-0.83; P = 0.002), and total vessel revascularization (OR 0.57; 95% CI 0.41-0.80; P = 0.001) were significantly decreased in the patients in which DES were used compared to BMS. This reduction in mortality and MACE events associated with DES use appears to be limited to registry studies and not randomized controlled studies. CONCLUSIONS: Our meta-analysis suggests DES use to be safe in SVG PCI and associated with reduced mortality and MACE rates with reductions in revascularization also observed. [less ▲]

AIMS: PCI with drug eluting stents (DES) has been shown to reduce restenosis and major adverse cardiac event (MACE) rates compared to bare metal stents (BMS) in native coronary vessels, although outcomes in saphenous vein graft (SVG) lesions are less clear. We retrospectively studied 388 consecutive patients admitted to our centre for SVG PCI to assess mortality and MACE outcomes (defined as composite endpoint of all-death, stroke, myocardial infarction, stent thrombosis and target lesion (TLR)/vessel (TVR) revascularisation) associated with BMS and DES use. METHODS AND RESULTS: Two hundred and nineteen (219) patients had BMS and 169 had DES (total 388 patients). Mean follow up was 41.9+/-23.5 months. No significant differences were observed in mortality (14.2% vs. 11.8%) or MACE (37.6% vs. 35.8%) between the BMS and DES groups at four years follow-up or at other intervening time points studied. Similarly, no differences in TVR/TLR rates were observed over a similar time period (19.8% vs. 21.6%). CONCLUSIONS: We have observed that DES and BMS use in SVG PCI have comparable mortality and MACE rates, and that in contrast to PCI in native coronary arteries, DES do not reduce revascularisation rates in our study cohort.
