umirolimus and Postoperative-Complications

The first CE-approved bioresorbable vascular scaffold (BVS) is effective at treating simple lesions and stable coronary artery disease, but it has yet to be assessed versus the best-in-class drug-eluting stents (DES).. This study sought to compare the performance of a BVS with that of everolimus-eluting stents (EES) and biolimus-eluting stents (BES) in all-comer patients.. The EVERBIO II (Comparison of Everolimus- and Biolimus-Eluting Stents With Everolimus-Eluting Bioresorbable Vascular Scaffold Stents II) trial was a single-center, assessor-blinded study of 240 patients randomly assigned in a 1:1:1 ratio to EES, BES, or BVS. The only exclusion criterion was a reference vessel diameter >4.0 mm, which precluded treatment with BVS. The primary endpoint was angiographic late lumen loss (LLL) at 9 months. Secondary endpoints included patient-oriented major acute coronary events (MACE) (death, myocardial infarction [MI], and any revascularization), device-oriented MACE (cardiac death, MI, and target lesion revascularization), and stent thrombosis at the 9-month clinical follow-up.. Follow-up angiography was performed in 216 patients (90.7%) at 9 months. In-stent LLL was similar between patients treated with BVS (0.28 ± 0.39 mm) and those treated with EES/BES (0.25 ± 0.36 mm; p = 0.30). Clinical outcomes were similar at 9 months: the patient-oriented MACE rate was 27% in BVS and 26% in the EES/BES group (p = 0.83) and the device-oriented MACE rate was 12% in BVS and 9% in the EES/BES group (p = 0.6).. New-generation metallic DES (EES/BES) were not superior to BVS in terms of angiographic LLL and clinical outcomes.

There is a paucity of data reporting the clinical outcomes of biodegradable polymer biolimus-eluting stent (BP-BES) compared with durable polymer everolimus-eluting stent (DP-EES) beyond 1 year after stent implantation when the polymer is fully degraded.. The NOBORI Biolimus-Eluting Versus XIENCE/PROMUS Everolimus-Eluting Stent Trial (NEXT) is a prospective, multicenter, randomized, open-label, noninferiority trial comparing BP-BES with DP-EES in patients scheduled for percutaneous coronary intervention using drug-eluting stent (DES) without any exclusion criteria among 98 participating centers in Japan. The trial was designed to evaluate noninferiority of BP-BES relative to DP-EES in terms of any target-lesion revascularization at 1 year and death or myocardial infarction at 3 years. Between May and October 2011, 3235 patients were randomly assigned to receive either BP-BES (1617 patients) or DP-EES (1618 patients). Complete 3-year follow-up was achieved in 97.6% of patients. At 3 years, the primary safety end point of death or myocardial infarction occurred in 159 patients (9.9%) in the BP-BES group and in 166 patients (10.3%) in the DP-EES group, demonstrating noninferiority of BP-BES relative to DP-EES (P noninferiority<0.0001 and P superiority=0.7). Cumulative incidence of target-lesion revascularization was not significantly different between the 2 groups (7.4% versus 7.1%; P=0.8). By a landmark analysis at 1 year, the cumulative incidences of death or myocardial infarction and target-lesion revascularization were also not significantly different between the 2 groups (4.6% versus 5.2%; P=0.46 and 3.3% versus 2.7%; P=0.39, respectively).. Safety and efficacy outcomes of BP-BES were non inferior to those of DP-EES 3 years after stent implantation.. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01303640.

Recent improvements in coronary stent design have focussed on thinner struts, different alloys and architecture, more biocompatible polymers, and shorter drug absorption times. This study evaluates safety and efficacy of a newer generation thin-strut cobalt chromium sirolimus-eluting coronary stent (SES, Ultimaster) in comparison with a second-generation thicker strut stainless steel biolimus-eluting stent (BES, Nobori) in percutaneous coronary intervention (PCI) practice.. A propensity score analysis was performed to adjust for differences in baseline characteristics of 8137 SES patients and 2738 BES patients of two PCI registries (e-Ultimaster and NOBORI 2). An independent clinical event committee adjudicated all endpoint-related adverse events.. The use of SES, as compared with BES was associated with a significantly lower rate of myocardial infarction (MI) (1.2% vs 2.2%; P = 0.0006) and target vessel-related MI (1.1% vs 1.8%; P = 0.002) at 1 year. One-year composite endpoints of all predefined endpoints were lower in patients undergoing SES implantation (target lesion failure: 3.2% vs 4.1%; P = 0.03, target vessel failure: 3.7% vs 5.0%; P = 0.003, patient-oriented composite endpoint 5.7% vs 6.8%; P = 0.03). No significant differences between SES and BES were observed in all-cause death (2.0% vs 1.6%; P = 0.19), cardiac death (1.2% vs 1.2%; P = 0.76) or stent thrombosis (0.6% vs 0.8%; P = 0.43).. These findings suggest an improved clinical safety and efficacy of a newer generation thin-strut SES as compared with a second-generation thicker strut BES.

Biolimus-eluting stents (BES) have similar efficacy and safety compared with cobalt chromium everolimus-eluting stents (CoCr-EES), whereas it is unclear whether the same applies to small vessel disease. We sought compare clinical outcomes between BES and CoCr-EES in patients with small vessel disease.. A total of 1,132 patients treated only with BES (612 patients) or EES (520 patients) in small vessel disease (stent size 2.5-mm) were retrospectively analyzed. We assessed the cumulative 2-year incidence of major adverse cardiovascular events (MACE), defined as a composite of cardiac death, myocardial infarction (MI), definite stent thrombosis (ST), and clinically driven target lesion revascularization (CD-TLR). The cumulative 2-year incidence of MACE was similar between the two groups (12.1% vs. 11.8%, P = 0.77). The cumulative incidence of cardiac death, CD-TLR, and definite ST were also not significantly different between both groups (3.2% vs. 3.6%, P = 0.78; 8.3% vs. 8.4%, P = 1.00; 0.33% vs. 0.21%, P = 0.66, respectively). After multivariate adjusting, the adjusted risk of BES group relative to CoCr-EES group for MACE was not significantly different (hazard ratio [HR]: 0.78, 95% confidential interval [CI]: 0.53-1.15, P = 0.20). Similarly, no significant difference in the adjusted risks for cardiac death and CD-TLR were observed between the two groups (HR: 0.62, 95% CI: 0.28-1.37, P = 0.24; HR: 0.81, 95% CI: 0.51-1.29, P = 0.38).. Two-year clinical outcomes of BES are similar to those of CoCr-EES in patients with small vessel disease. The use of BES is acceptable for small coronary artery disease. © 2015 Wiley Periodicals, Inc.
