Abstract 3438: Comparison of Endothelial Progenitor Cell Capture Stent with Bare Metal Stent In Patients Undergoing Primary Percutaneous Coronary Intervention for Acute Myocardial Infarction
Background: The endothelial progenitor cell (EPC) capture bio-engineered stent (Genous®stent, OrbusNeich) was designed to attract circulating EPCs and promote rapid endothelization. The aim of this study was to compare clinical outcomes between patients with ST-segment elevation myocardial infarction (STEMI) who received this stent versus those who received Liberte (Boston Scientific) bare metal stents.
Methodology: Three hundred and forty two patients who presented to our centers with STEMI without cardiogenic shock and underwent primary PCI with either EPC Capture-or bare metal stent implantation were enrolled in this study. All patients received dual anti-platelet therapy for a month; and statin therapy was initiated soon after PCI. The study endpoints were major adverse cardiac events (MACE) at 30 days, 6 months and 1 year.
Results: A total of 164 EPC Capture stents and 178 BMS were implanted. Baseline patient characteristics were comparable in the 2 groups. The mean lesion length in the 2 groups were 20.4.0 ± 5.1 and 22.8 ± 7.6mm, and the mean reference vessel diameter 3.14 ± 0.65 and 2.70 ± 1.14 mm respectively. At 6 months, the results were:
Conclusion: There was no significant difference in MACE at 6 month between EPC Capture-and bare metal stents in patients with STEMI who underwent primary PCI. The 1-year data will be presented at the meeting.
