Abstract
BACKGROUND The HELIOS stent is a sirolimus-eluting stent with a biodegradable polymer and titanium oxide film as the tie-layer. The study aimed to evaluate the safety and efficacy of HELIOS stent in a real-world setting. METHODS The HELIOS registry is a prospective, multicenter, cohort study conducted at 38 centers across China between November 2018 and December 2019. A total of 3060 consecutive patients were enrolled after application of minimal inclusion and exclusion criteria. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, non-fatal target vessel myocardial infarction (MI), and clinically indicated target lesion revascularization (TLR) at 1-year follow-up. Kaplan-Meier methods were used to estimate the cumulative incidence of clinical events and construct survival curves. RESULTS A total of 2998 (98.0%) patients completed the 1-year follow-up. The 1-year incidence of TLF was 3.10% (94/2998, 95% closed interval: 2.54-3.78%). The rates of cardiac death, non-fatal target vessel MI and clinically indicated TLR were 2.33% (70/2998), 0.20% (6/2998), and 0.70% (21/2998), respectively. The rate of stent thrombosis was 0.33% (10/2998). Age ≥60 years, diabetes mellitus, family history of coronary artery disease, acute myocardial infarction at admission, and device success were independent predictors of TLF at 1 year. CONCLUSION The 1-year incidence rates of TLF and stent thrombosis were 3.10% and 0.33%, respectively, in patients treated with HELIOS stents. Our results provide clinical evidence for interventional cardiologists and policymakers to evaluate HELIOS stent. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT03916432.

Early vascular healing after neXt-generation drug-eluting stent implantation in Patients with non-ST Elevation acute Coronary syndrome based on optical coherence Tomography guidance and evaluation (EXPECT): study protocol for a randomized controlled trial. Front Cardiovasc Med 2023; 10:1003546. [PMID: 36910518 PMCID: PMC9995825 DOI: 10.3389/fcvm.2023.1003546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 02/06/2023] [Indexed: 02/25/2023] Open
Abstract
Background There is limited evidence about vessel wall healing response following implantation of next-generation drug-eluting stents (DES) in patients admitted with a non-ST elevation acute coronary syndrome (NSTE-ACS). Cumulative data indicate that optical coherence tomography (OCT) imaging can optimize percutaneous coronary intervention results and expedite stent endothelialization in the general population but there is lack of data in NSTE-ACS patients. Methods The EXPECT study is an investigator-initiated, prospective, randomized trial to assess early vascular healing response following next-generation DES implantation in patients admitted with NSTE-ACS based on OCT guidance and evaluation. Sixty patients are randomized at 1:1:1 ratio to OCT-guided percutaneous coronary intervention (PCI) with 3-month follow-up OCT imaging (O3 group, n = 20), to angiography-guided PCI with 3-month follow-up OCT imaging (A3 group, n = 20) and to angiography-guided PCI with 6-month follow-up OCT imaging (A6 group, n = 20). The primary endpoint of the study is stent strut coverage rate at 3- or 6- month follow-up in the studied groups. The secondary endpoints of the study include OCT imaging endpoints, clinical endpoints, and molecular biology endpoints at the different time points. The clinical endpoints comprised of major cardiovascular adverse events and individual components. The molecular biology endpoints comprised of lipid levels and the levels of inflammatory indicators. Discussion The findings of the EXPECT study are anticipated to provide novel insights into vessel wall healing in NSTE-ACS population following implantation of next-generation DES, underscore the value of OCT imaging in expediting strut coverage in this setting, and explore the potential of an early discontinuation of dual antiplatelet therapy (DAPT) in this population.

Abstract
OBJECTIVES To analyze the 3-year outcomes of the biodegradable polymer cobalt-chromium sirolimus-eluting stent (EXCROSSAL) in CREDIT II AND III TRIALS. BACKGROUND Though approved by CFDA, the long-term safety and efficacy of EXCROSSAL is still unknown. METHODS CREDIT II was a randomized trial comparing the EXCROSSAL versus EXCEL stents in patients with up to two de novo coronary lesions, and CREDIT III was a prospective, single-arm study evaluating the efficacy and safety of EXCROSSAL in broad types of de novo coronary artery lesions. We pooled the 3-year follow-up data of the EXCROSSAL arm of the CREDIT II and CREDIT III Trials. The primary outcome was 3-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction (TV-MI), and clinically indicated target lesion revascularization (CI-TLR). The patient-oriented composite endpoint (PoCE) (all-cause death, all MI, or any revascularization) and stent thrombosis (ST) were also analyzed. RESULTS A total of 833 patients were included in this study. The incidence of TLF and PoCE in the 3-year follow-up were 7.6% and 12.5%, respectively. ST occurred in 0.6% of patients. In the subgroup analyses, TLF was significantly higher in small target vessels, multi-lesion PCI, and multi-vessel disease. CONCLUSIONS The 3-year follow-up analysis confirmed low rates of TLF and ST in EXCROSSAL, which is similar to the most widely used new generation durable polymer drug-eluting stent.

[PMID: 31695399 PMCID: PMC6805243 DOI: 10.2147/vhrm.s200699] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Accepted: 09/16/2019] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Although a number of drug-eluting stents have been developed with different design, composition, and polymers, the search for an ideal drug-eluting stent is ongoing. The Tetriflex (Sahajanand Medical Technology, Surat, India) is a newer-generation, ultrathin (60 µm) biodegradable polymer-coated sirolimus-eluting stent (SES) designed with a unique long dual Z-link on a cobalt-chromium alloy. The present registry aimed to evaluate the safety and clinical outcomes of the Tetriflex SES at 6-month post-implantation. METHODS This was an investigator-initiated, retrospective, multicenter, single-arm, observational registry conducted at five tertiary-care centers in India. A total of 1,269 consecutive patients with coronary artery disease who underwent implantation of at least one Tetriflex SES between March 2017 and March 2018 were included. The primary outcome was considered a composite of cardiac death, myocardial infarction and target-lesion revascularization (TLR) at 6-month follow-up. Stent thrombosis was evaluated as a safety outcome at 6-month follow-up. RESULTS The mean age of patients was 54.99±10.80 years. Among 1,515 lesions treated with 1,682 Tetriflex SES, 58.3% were type C lesions. Six-month follow-up was done for 1,245 of 1,269 (98.1%) patients. At 6 months, composite events had occurred in 31 (2.5%) patients, consisting of ten (0.8%) cardiac deaths, 16 (1.3%) myocardial infarctions, and five (0.4%) TLRs. Stent thrombosis was observed in seven (0.56%) cases at 6 months. A subgroup analysis between diabetic and nondiabetic patients did not reveal any statistically significant difference for clinical outcomes at 6-month follow-up. CONCLUSION The results of the current registry outline the safety and effectiveness of the Tetriflex SES in real-world patients, as it displayed favorable clinical outcomes at 6-month follow-up, with low incidence of TLR and stent thrombosis.

Krishnagopal A, Reddy A, Sen D. Stent-mediated gene and drug delivery for cardiovascular disease and cancer: A brief insight. J Gene Med 2018; 19. [PMID: 28370939 DOI: 10.1002/jgm.2954] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2017] [Revised: 03/23/2017] [Accepted: 03/28/2017] [Indexed: 12/17/2022] Open
Abstract
This review concisely recapitulates the different existing modes of stent-mediated gene/drug delivery, their considerable advancement in clinical trials and a rationale for other merging new technologies such as nanotechnology and microRNA-based therapeutics, in addition to addressing the limitations in each of these perpetual stent platforms. Over the past decade, stent-mediated gene/drug delivery has materialized as a hopeful alternative for cardiovascular disease and cancer in contrast to routine conventional treatment modalities. Regardless of the phenomenal recent developments achieved by coronary interventions and cancer therapies that employ gene and drug-eluting stents, practical hurdles still remain a challenge. The present review highlights the limitations that each of the existing stent-based gene/drug delivery system encompasses and therefore provides a vision for the future with respect to discovering an ideal stent therapeutic platform that would circumvent all the practical hurdles witnessed with the existing technology. Further study of the improvisation of next-generation drug-eluting stents has helped to overcome the issue of restenosis to some extent. However, current stent formulations fall short of the anticipated clinically meaningful outcomes and there is an explicit need for more randomized trials aiming to further evaluate stent platforms in favour of enhanced safety and clinical value. Gene-eluting stents may hold promise in contributing new ideas for stent-based prevention of in-stent restenosis through genetic interventions by capitalizing on a wide variety of molecular targets. Therefore, the central consideration directs us toward finding an ideal stent therapeutic platform that would tackle all of the gaps in the existing technology.
