Objectives: To assess the long-term safety and efficacy of a sirolimus-eluting stent with bioresorbable polymer (BP-SES; Ultimaster), in comparison to a benchmark everolimus-eluting, permanent polymer stent (PP-EES; Xience), in a prespecified subgroup of patients with multivessel coronary artery disease (MVD) enrolled in the CENTURY II trial.

Background: The use of coronary stenting in high-risk subgroups, like MVD patients, is rising. The clinical evidence, including long-term comparative analysis of the efficacy and safety benefits of different new-generation drug eluting stents, however, remains insufficient.

Article Synopsis
  • This study aimed to explore how angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) impact the occurrence of heart failure (HF) following an acute myocardial infarction (AMI), considering patients' left ventricular ejection fraction (LVEF).
  • Researchers analyzed data from 8,169 AMI patients discharged from two Spanish hospitals between 2010 and 2016, employing various statistical methods to assess the relationship between ACEI/ARB use and heart failure admissions.
  • Findings indicated that while ACEIs/ARBs showed no significant benefit for patients with LVEF over 40%, they significantly reduced HF admissions in patients with LVEF 40% or lower, suggesting

Objectives: The REAC-TAVI (Assessment of platelet REACtivity after Transcatheter Aortic Valve Implantation) trial enrolled patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) pre-treated with aspirin + clopidogrel, aimed to compare the efficacy of clopidogrel and ticagrelor in suppressing high platelet reactivity (HPR) after TAVI.

Background: Current recommendations support short-term use of aspirin + clopidogrel for patients with severe AS undergoing TAVR despite the lack of compelling evidence.

Methods: This was a prospective, randomized, multicenter investigation.

Aims: The MASTER study was designed to compare the performance of a new biodegradable polymer sirolimus-eluting stent (BP-SES) with a bare metal stent (BMS) in patients with ST-segment elevation myocardial infarction (STEMI).

Methods And Results: The study was a prospective, randomised (3:1), controlled, single-blind multicentre trial that enrolled 500 STEMI patients within 24 hours of symptom onset during 2013-2015. Three hundred and seventy-five patients were treated with BP-SES and 125 with BMS.

Aims: The aim of this study was to establish the long-term safety and efficacy of a sirolimus-eluting stent with bioresorbable polymer (BP-SES; Ultimaster) by comparison with an everolimus-eluting stent with permanent polymer (PP-EES; XIENCE).

Methods And Results: CENTURY II (Clinical Evaluation of New Terumo Drug-Eluting Coronary Stent System in the Treatment of Patients with Coronary Artery Disease) is a large-scale, prospective, multicentre, randomised single-blind, controlled, non-inferiority trial conducted at 58 study sites globally, including Europe, Japan and Korea, powered to prove non-inferiority for freedom from target lesion failure (TLF: cardiac death, target vessel-related myocardial infarction [MI] and target lesion revascularisation) at nine months. Patients requiring a percutaneous coronary intervention (PCI) were randomised (1:1) to BP-SES (n=551) or PP-EES (n=550).
