9-year clinical follow-up of patients with ST-segment elevation myocardial infarction with Genous or TAXUS Liberté stents. PLoS One 2018; 13:e0201416. [PMID: 30080886 PMCID: PMC6078296 DOI: 10.1371/journal.pone.0201416] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Accepted: 07/10/2018] [Indexed: 02/08/2023] Open
Abstract
Objectives This matched-cohort retrospective study investigated the long-term (9-year) safety and efficacy outcomes of patients with ST-segment elevation myocardial infarction (STEMI) and primary percutaneous coronary intervention (pPCI) with Genous (n = 102) versus TAXUS Liberté (n = 101) stents in 2006–2008. Background In the era of off-label use of drug-eluting stents for pPCI in patients with STEMI, the use of first-generation Genous stents (endothelial progenitor cell capture stents that have a passive coating and accelerate re-endothelialization) was proposed. Methods The primary endpoint was 9-year major adverse cardiac and cerebrovascular events (MACCE), including all-cause death, re-infarction, target vessel revascularization (TVR), and stroke. The secondary endpoints were the separate primary endpoint events at pre-defined time-points (in-hospital, 6 months, and yearly) and stent thrombosis. Time-dependent 9-year composite MACCE, all-cause death, and TVR were compared using Kaplan-Meier estimates and multivariate Cox regression models. Results Propensity score analysis confirmed the comparability of the groups. Patients in the Genous and TAXUS groups had 7 and 1 acute definitive stent thrombosis events, respectively (p<0.001). There was a trend towards higher in-hospital MACCE in the Genous group (10.8%) versus the TAXUS group (4.0%). Kaplan-Meier analysis showed that 9-year MACCE was significantly worse in the Genous than in the TAXUS group. The in-hospital, 6-month, 1-year, and 9-year mortality rates were 7.8%, 8.8%, 9.8%, and 23.5% in the Genous group and 2.0%, 3.0%, 4.0%, and 16.8% in the TAXUS group. Conclusions Higher peri-procedural, in-hospital, and short-term mortality led to worse outcomes for first-generation Genous stents versus TAXUS Liberté stents for pPCI in STEMI. TAXUS Liberté stents had more favorable 9-year clinical outcomes.

Prevention of in-stent restenosis with endothelial progenitor cell (EPC) capture stent placement combined with regional EPC transplantation: An atherosclerotic rabbit model. Cardiol J 2018; 26:283-291. [PMID: 29611172 DOI: 10.5603/cj.a2018.0027] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 12/14/2017] [Accepted: 01/15/2018] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Even with drug-eluting stents, the risk of in-stent restenosis (ISR) remains high. The goal of this study was to investigate the use of an endothelial progenitor cell (EPC) capture stent plus regional EPC transplantation to reduce the ISR rate. METHODS Endothelial progenitor cell capture stents were fabricated using fibrin gel and anti-CD34 plus anti-VEGFR-2 dual antibodies. Twenty male New Zealand white rabbits established as an atherosclerotic model were randomly divided into two groups: group 1 (n = 10), in which EPC capture stents were deployed into the right iliac artery; and group 2 (n = 10), in which sirolimus-eluting stents were placed. In both groups, EPCs were transplanted into target vessels beyond the stents, with outflow blocked. Radiologic-pathologic correlation outcomes were reviewed after 2 months. RESULTS The technical success rate of EPC capture stent placement plus EPC transplantation was 100%. The ISR rate in group 1 was lower than in group 2 (1/10 vs. 4/10; p > 0.05). Minimal luminal diameters were larger in group 1 than in group 2 (computed tomographic angiography, 1.85 ± 0.15 mm vs. 1.50 ± 0.20 mm; duplex ultrasound, 1.90 ± 0.10 mm vs. 1.70 ± 0.30 mm; p > 0.05). Transplanted EPCs were tracked positively only in group 1. Pathologic analysis demonstrated neointimal hyperplasia thickness of 0.21 ± 0.09 mm in group 1 vs. 0.11 ± 0.07 mm in group 2 (p < 0.05). CONCLUSION Endothelial progenitor cell capture stent placement plus local EPC transplant decreases the ISR rate through thrombosis reduction rather than through neointimal hyperplasia inhibition.

Five-year follow-up of the endothelial progenitor cell capturing stent versus the paxlitaxel-eluting stent in de novo coronary lesions with a high risk of coronary restenosis. Catheter Cardiovasc Interv 2017; 91:1212-1218. [PMID: 28868810 DOI: 10.1002/ccd.27249] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Revised: 06/06/2017] [Accepted: 07/22/2017] [Indexed: 11/06/2022]
Abstract
OBJECTIVES To assess the long-term safety and clinical efficacy of the Genous endothelial progenitor cell capturing stent (ECS) compared with the TAXUS Liberté paclitaxel-eluting stent (PES) in lesions with a high risk of restenosis. BACKGROUND Instead of the use of cytotoxic or cytostatic drugs in drug-eluting stents, a "pro-healing" approach in ECS may overcome impeded healing response due to delayed functional endothelialization of the stent struts. METHODS In the prospective, randomized TRIAS pilot study 193 patients with coronary artery lesions carrying a high risk of restenosis were included (ECS: n = 98, PES: n = 95). The primary focus of this analysis was target vessel failure (TVF) at 5 years. Dual antiplatelet therapy was prescribed for ≥1 month after ECS and for ≥6 months after PES. RESULTS At 5 years follow-up, no significant differences were found in TVF (ECS 24% vs. PES 29%, risk difference 95% confidence interval (RDCI) -17.3% to 7.4%). Between 2 and 5 years after the index procedure, low numbers of TVF were observed in ECS compared with PES (ECS 4% vs. PES 16%, RDCI -20.8% to -2.3%). There was no definite stent thrombosis in ECS compared with four patients in the PES group. CONCLUSION This is the first randomized study providing very long-term clinical efficacy and safety of the ECS in lesions carrying a high risk of restenosis. At 5 years follow-up, TVF rates in ECS group are numerically lower compared with PES due to an increase of events between 2 and 5 years after the index procedure.

Abstract
PURPOSE The aim of the study was the evaluation of the number of circulating endothelial progenitor cells (CEPCs) in healthy people and the assessment of the variability of quantitative of CEPCs after 6 weeks. MATERIAL AND METHODS The study involved 48 healthy individuals; the group consisted of 24 men and 24 women; the mean age of 34. The criterion for the patients' eligibility for the study was the absence of diabetes, thrombosis and cardiovascular diseases such as atherosclerosis, hypertension, and heart failure. Neither did the respondents take any medication that could clearly affect the value of the results. In the whole blood samples the number of circulating endothelial progenitor cells was determined using flow cytometry. During the analysis the fluorescence of 100,000 cells was measured. CEPCs were identified with immunophenotype CD45-, CD31+, CD34+, CD133+. RESULTS In the study, the median of the number of circulating endothelial progenitor cells in the whole group was 0.41/μL. There was also recorded an increased number of CEPCs after 6 weeks, as compared to the baseline; the difference was significant. There were no differences in the number of CEPCs between the women and the men. There was found no effect on the number of CEPCs factors such as: smoking, physical activity and alcohol consumption. CONCLUSIONS The study showed that in healthy individuals the gender had no essential effect on the number of endothelial progenitor cells. Based on the demographic and lifestyle data acquired, it is difficult to explain the increase number of CEPCs after 6 weeks.

Abstract
Physical activity has a therapeutic role in cardiovascular disease (CVD), through its beneficial effects on endothelial function and cardiovascular system. Circulating endothelial progenitor cells (EPCs) are bone marrow (BM) derived cells that represent a novel therapeutic target in CVD patients, because of their ability to home to sites of ischemic injury and repair the damaged vessels. Several studies show that physical activity results in a significant increase in circulating EPCs, and, in particular, there are some evidence of the beneficial exercise-induced effects on EPCs activity in CVD settings, including coronary artery disease (CAD), heart failure (HF), and peripheral artery disease (PAD). The aim of this paper is to review the current evidence about the beneficial effects of physical exercise on endothelial function and EPCs levels and activity in both healthy subjects and patients with CVD.

Abstract
Stent thrombosis (ST) is a rare but life-threatening complication of coronary artery stenting. Although dual-antiplatelet therapy is an effective management strategy in reducing the risk for ST, some patients may need to interrupt their regimens because of unforeseen circumstances, such as the requirement for surgery. In conclusion, this case presentation highlights some pertinent issues related to ST, including its risk factors, the perioperative management of antiplatelet agents, and treatment for ST.
