AIMS: Drug eluting stents (DES) have had a great impact in reducing in-stent restenosis (ISR) in de novo lesions. However, long-term data regarding effectiveness and safety of these stents in treating bare metal stent (BMS) ISR are limited. We report long-term clinical outcomes in a cohort of patients with BMS-ISR treated with DES between April 2002 and December 2003 at our institution. METHODS AND RESULTS: Sixty-nine consecutive patients with significant BMS-ISR were treated with DES implantation. Sirolimus DES were used in 43 patients and paclitaxel DES in 26. All patients were followed up to determine the incidence of major adverse cardiac event (MACE) rates (all-cause death, myocardial infarction, or target vessel revascularisation [TVR]), angina class and the need for clinically driven angiography. The mean age of the cohort was 58.6 +/- 10.8 years; 68% were male, 33% were diabetic, 50% had hypertension, 78% were on statin therapy and 59% were current (19%) or previous (41%) smokers. The clinical presentation of ISR was with chronic stable angina in 54 patients, 12 had a non-ST elevation acute coronary syndrome and three presented with ST-elevation myocardial infarction. Multivessel stenting was performed in 21 patients and bifurcation stenting in seven patients. Over a mean follow period of 4.9 years, the first event MACE rate was 20% (17 events in 14 patients - eight deaths of which three were cardiac, two non-fatal myocardial infarctions and seven TVR). Excluding non-cardiac death, the adjusted MACE rate was 14.5% (12 events in 10 patients). At long-term follow-up, mean Canadian angina class decreased from 2.3 +/- 0.7 pre-procedure to 1.2 +/- 0.4, 65% of patients were angina free and 80% were free of MACE. No differences in long-term outcomes were observed between patients receiving paclitaxel and sirolimus DES. CONCLUSIONS: The use of DES for the treatment of BMS-ISR is safe and effective over a mean follow-up period of nearly five years. To our knowledge, this represents the longest follow-up data of real world patients treated in a single interventional centre. [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.
