Article Synopsis
  • The study aimed to compare the safety and effectiveness of two types of stents in patients at high bleeding risk who were undergoing abbreviated dual antiplatelet therapy after coronary stenting: the ultrathin-strut Supraflex Cruz stent and the thin-strut Ultimaster Tansei stent.
  • A total of 741 patients were enrolled in a randomized trial where they received one of the two stents, and the primary outcome measured was a combination of serious adverse events over one year.
  • Results showed that 15.4% of patients with the Supraflex Cruz stent experienced adverse outcomes compared to 17.1% with the Ultimaster Tansei stent, indicating a potential slight difference

Unlabelled: The optimal treatment strategy for coronary bifurcation lesions by percutaneous coronary intervention (PCI) is complex and remains a subject of debate. Current guidelines advise a stepwise provisional approach with optional two-stent strategy. However, a two-stent strategy, both upfront and stepwise provisional, is technically demanding.

Up to 45% of patients who underwent percutaneous coronary intervention (PCI) may have a high bleeding risk (HBR), depending on the bleeding risk definition. This condition is often associated with an enhanced risk of thrombotic events with a negative impact on short- and long-term outcomes, making the choice of an appropriate antithrombotic regimen after PCI particularly challenging. Advances in stent technologies, in which the introduction of newer generations of thinner strut drug-eluting stents (DES), have significantly reduced the rate of thrombotic complications and may justify a shorter dual antiplatelet therapy (DAPT) duration.

Background: The PIONEER III trial demonstrated noninferiority of 12-month target lesion failure (TLF) with the Supreme DES (Sinomed), a thin-strut cobalt-chromium, biodegradable polymer, sirolimus-eluting stent, compared with a durable polymer, everolimus-eluting (XIENCE/PROMUS) stent (DP-EES). The relative safety and effectiveness of the Supreme DES in patients with acute coronary syndromes (ACS) and those with chronic coronary syndromes (CCS) is not known.

Methods: PIONEER III was a prospective, multicenter, international, 2:1 randomized trial stratified by clinical presentation.

Background: In the TALENT study, the sirolimus-eluting ultrathin strut Supraflex stent was non-inferior to the XIENCE stent for a device-oriented composite endpoint (DoCE: defined as cardiac death, target vessel myocardial infarction [TV-MI], or clinically indicated target lesion revascularisation [CI-TLR]) at 12 months.

Aims: This study investigated the 3-year outcomes of the TALENT trial and long-term impact of ultrathin drug-eluting stents (DES), compared to the XIENCE everolimus-eluting thin stent.

Methods: The TALENT trial is a prospective, multicentre, randomised all-comers trial comparing the Supraflex sirolimus-eluting stent with the XIENCE everolimus-eluting stent, with planned follow-up for 3 years.

  • The study examined the long-term (five-year) clinical outcomes of the Absorb bioresorbable vascular scaffold (BVS) compared to the XIENCE everolimus-eluting stent (EES) in patients with coronary artery disease.
  • There was no significant difference in target vessel failure rates between the two devices; however, the Absorb BVS had a notably higher incidence of device thrombosis (4.8% vs. 1.5% for XIENCE).
  • The use of prolonged dual antiplatelet therapy (DAPT) appeared to reduce the risk of scaffold thrombosis over the five-year follow-up period.

Background: Despite the advances of potent oral P2Y inhibitors, their onset of action is delayed, which might have a negative impact on clinical outcome in patients undergoing percutaneous coronary intervention (PCI). Trials conducted in the United States of America have identified cangrelor as a potent and rapid-acting intravenous P2Y inhibitor, which has the potential of reducing ischemic events in these patients without an increase in the bleeding. As cangrelor is rarely used in The Netherlands, we conducted a nationwide registry to provide an insight into the use of cangrelor in the management of patients with suboptimal platelet inhibition undergoing (primary) PCI (the Dutch Cangrelor Registry).

Background: Patients with acute coronary syndrome (ACS) who are carrying CYP2C19 loss-of-function alleles derive less benefit from clopidogrel treatment. Despite this, in elderly patients, clopidogrel might be preferred over more potent P2Y inhibitors due to a lower bleeding risk. Whether CYP2C19 genotype-guided antiplatelet treatment in the elderly could be of benefit has not been studied specifically.

Background: Accelerated endothelial healing after targeted antiproliferative drug delivery may limit the long-term inflammatory response of drug-eluting stents (DESs). The novel Supreme DES is designed to synchronize early drug delivery within 4 to 6 weeks of implantation, leaving behind a prohealing permanent base layer. Whether the Supreme DES is safe and effective in the short term and can improve long-term clinical outcomes is not known.

There are no randomised data on which antiplatelet agent to use in elderly patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and an indication for oral anticoagulation (OAC). The randomised POPular Age trial, in patients of 70 years or older with NSTE-ACS, showed a reduction in bleeding without increasing thrombotic events in patients using clopidogrel as compared to ticagrelor. In this sub-analysis of the POPular AGE trial, we compare clopidogrel with ticagrelor in patients with a need for oral anticoagulation.
