Abstract: Aims: The Genous™ endothelial progenitor cell (EPC) capture stent is a bioengineered R stent coated with immobilised antibodies on its stent struts to allow for the capture of circulating EPCs to promote rapid endothelisation. We assessed the impact of this stent in the primary percutaneous coronary intervention (PCI) of patients with acute ST-elevation myocardial infarction (STEMI) and examined its long term clinical outcomes. Methods and results: All patients with acute STEMI without cardiogenic shock who underwent primary PCI between January 2005 and April 2007 and received the stent were enrolled in the study. The study endpoints were major adverse cardiac events (MACE) defined as death, MI and target vessel revascularisation (TVR) at 30 days, six months and one year. A total of 321 enrolled patients received 357 EPC capture stents during the study period. The cohort comprises 81.0% males with mean age of 54.6±11.6 years. The mean stent length used was 20.98±5.50 mm and mean stent size was 2.99±0.32 mm. Ninety-four percent of patients achieved Thrombolysis in Myocardial Infarction (TIMI) 3 flow post-procedurally. The cumulative MACE rate was 8.1% at 30 days, 10.0% at six months and 12.2% at one year. There was one patient who developed acute stent thrombosis and another two with subacute stent thromboses. No late thrombosis or late cardiac mortality was observed in our cohort. The need for TVR was 4.4% at one year. Conclusions: The use of EPC capture stents in patients who underwent primary PCI for STEMI is safe and showed good clinical outcomes, with low rates of TVR and no late stent thrombosis. © Europa Edition.
