Abstract Background The Endothelial Progenitor Cell (EPC) stent was designed to capture circulating EPCs and promote early stent re-endothelization. Erythropoietin (EPO) stimulates mobilization of EPC from the bone marrow. Combination of EPO and the EPC stent in the setting of ST-segment elevation myocardial infarction (STEMI) has never been investigated. Methods STEMI patients enrolled in the HEBE-III trial were randomized to a single bolus of EPO or No-EPO after implantation of the EPC capture stent. Late lumen loss (LLL) was determined at 9-month angiographic follow-up. Clinical data was collected at 30 days and 12 months. Results 196 patients were randomized to EPO (n=100) or No-EPO (n=96). No significant difference in baseline characteristics was observed between the two groups. A significant reduction in angiographic LLL was observed with EPO (0.43±0.57mm) as compared to No-EPO (0.74±0.63mm) (p=0.011). At 12 months follow up, no difference with regard to death or re- infarction was observed in both groups, whereas significant reduction in the need for target vessel revacularization for the EPO versus No-EPO was observed with rates of 7.1% and 19.1% respectively (p=0.013). Angiographic and clinical results EPO (n=39) No-EPO (n=45) P-value Angiography   Lume late loss 0.43±0.57 0.74±0.63 0.011 12 months clinical   Death 0 0 ns   Re infarction 0 1 (2.2%) ns   Additional PCI 4 (10.3%) 17 (37.8%) 0.004   CABG 2 (5.1%) 2 (4.4%) ns   CVA 0 0 ns   Bleeding 3 (7.7%) 4 (8.9%) ns ns = not significant; CVA = cerebrovascular accident; CABG = coronary bypass graft; PCI = percutaneous coronary intervention. Conclusion In STEMI patients treated with EPC capture stent, additional EPO can further improve angiographic LLL

Background: Circulating endothelial progenitor cells (EPCs) have regenerative capacities and play an important role in vessel wall homeostasis. When attracted to the site of vessel wall injury, EPCs rapidly differentiate into a functional layer as part of the healing process. The Genous TM endothelial progenitor cell (EPC) capturing stent is coated with anti-human CD34+ antibodies which combine with circulating EPCs from the peripheral blood to the stent surface. Objective: This meta-analysis aims to explore the Genous TM endothelial progenitor cell capturing stent in coronary artery disease (CAD) adverse event rate after one-year follow-up. Methods: PubMed, EMBASE and, Google Scholar databases were searched for eligible studies. CAD survival data and clinicopathological features were analyzed by expected shortfall (ES) and 95% CI. Fixed-effect model and random-effect model are used for summary statistics. Results: 12 studies, including 15985 coronary artery disease (CAD) patients who received PCI treatment were included in this study. After 1-year follow-up, the rate of adverse event showed that the target vessel failure (TVF) was 8.5% (7.6%-17.4%), target vessel revascularization was 4.1% (TVR, 0-15.6%), target lesion revascularization was 4.2% (TLR, 3.7%-22%), myocardial infarction was 2.0% (MI, 1.8%-5.2%), major adverse cardiac events was 8.7% (MACE, 6.4%-28%), and the all-cause death was 4.0% (0-9.2). Conclusion: After one-year follow-up, the incidence rate of Genous stent adverse events was stable in CAD patients. The study showed a better evaluation of Genous stent, and it provides a better reference for CAD clinical treatment.

Abstract Introduction The Genous stent is a bare metal stent (BMS) together with a technique of capturing endothelial progenitor cells. The successor of the Genous endothelial progenitor cell capturing (EPC) stent, the COMBO stent, combines this technique with the drug eluting polymer. The current studies showed promising results of the COMBO stent, however the additional value of EPC technique in overcoming neointimal hyperplasia has yet to be proven. Purpose This study sought to evaluate the efficacy and safety of the Genous EPC stent compared to BMS in a patient population with low risk for restenosis. Methods TRIAS-LR was an investigator-initiated, prospective, multicentre, single blind trial randomizing patients with low risk of restenosis 1:1 to Genous ECS or BMS. Patients were recruited between 2007 and 2014 at 31 sites across Europe. The study enrolment was terminated at 70% of the planned inclusion due to slow enrolment and change of guidelines. Patients or lesions were considered low risk if all of the following criteria were met: 1) reference vessel diameter >2.8mm, 2) lesion length <20mm, 3) no thrombolysis in myocardial infarction (TIMI) flow of 0, and 4) patient without diabetes mellitus. Clinical follow-up was obtained yearly. The trial was monitored and independent clinical event committee adjudicated serious adverse clinical events. The primary endpoint was target lesion failure (TLF), composite of cardiac death, target-vessel myocardial infarction (TV-MI) or target lesion revascularization (TLR) at 1 year. Secondary endpoint included the composite of death or MI at 5-year follow-up. Results In total, 838 patients were enrolled of whom 422 patients with 476 lesions were randomly assigned to Genous EPC stent and 416 patients with 480 lesions to BMS. The mean age was 64 years, 74% were males and in 76% patients were treated in elective setting. At 1 year TLF had occurred in 3.6% (n=15) of the Genous arm and in 6.1% (n=25) of the BMS arm (p=0.094; risk difference of −2.5%). However, this difference disappeared, at 5-years of follow-up; TLF rate was 12.6% (n=51) in the Genous arm versus 14.3% (n=58) in the BMS arm (p=0.385; risk difference of −1.7%). The secondary objective of the composite death or MI at 5 years occurred in 11.6% (n=47) in the Genous arm and 9.9% (n=40) in the BMS arm (p=0.479; risk difference of 1.7%). At 5 years definite stent thrombosis (ST) occurred in 0.5% (n=2) of the Genous arm, no definite ST had occurred in the BMS arm (p=0.162). Conclusion TRIAS-LR trial showed no differences between Genous EPC and BMS throughout 5-year follow-up in patients considered as low risk of restenosis.
