Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: WOEST2 Registry is designed to recruit an unselected cohort of patients with AF and/or a heart valve prosthesis undergoing coronary revascularisation (PCI/CABG) within at least three European countries (Netherlands, Belgium, United Kingdom). The three international cohorts of patients reflect the spectrum of our study population within the geographic catchment regions. At least 15 hospitals of varying size and characteristics will participate in this study.

Who may be able to join

  • In order to be eligible to be included in this registry, a subject must meet ALL of the following criteria:
  • Patient is ≥ 18 years of age;
  • Patients with a diagnosis of atrial fibrillation (prior to hospitalisation ór during hospitalisation within 72h after coronary revascularisation) and/or with a heart valve prosthesis (aortic/mitral);
  • Chronic treatment with OAC or NOAC therapy at inclusion or the intention to start chronic treatment with OAC or NOAC within 72h after coronary revascularisation AND with intended duration of treatment for at least one year after inclusion in the registry;
  • Indication for coronary revascularisation by CABG or PCI (with deployment of at least 1 coronary stent);
  • Prescription of a P2Y12 inhibitor (clopidogrel, ticagrelor or prasugrel) because of CABG following acute coronary syndrome* and /or because of PCI (with deployment of at least 1 coronary stent).
  • Patient has provided written informed consent.

Who cannot join

  • A potential subject who meets ANY of the following criteria will be excluded from participation in this study:
  • Patients unable to sign informed consent (including mental disabled patients);
  • Patients with life expectancy < 1 year;
  • Allergy or intolerance to P2Y12 inhibitors.

About this study

Official title: An International Prospective Registry on Concomitant Use of Oral Anticoagulants and P2Y12 Inhibitors in Patients With Atrial Fibrillation or Heart Valve Prosthesis Undergoing Coronary Revascularisation.

The optimal antithrombotic therapy for patients with atrial fibrillation (AF) with a CHA2DS2-VASc score ≥1 with concomitant acute coronary syndrome (ACS) or revascularisation by percutaneous coronary intervention (PCI) with stenting, is still unknown. For these patients current North American and European guidelines recommend a triple therapy strategy, including vitamin K antagonists (VKA), aspirin and clopidogrel. A major drawback of this triple therapy strategy is a significant increase in the risk of major bleeding. Furthermore, the ommitance of aspirin and the introduction of more potent P2Y12 inhibitors as well as the non-vitamin K oral anticoagulants (NOAC), created numerous new antithrombotic treatment strategies for these patients with overlapping conditions. To date, evidence on the risks and benefits of these new antithrombotic treatment strategies is lacking.

The WOEST 2 Registry aims to improve medical care for patients with AF and/or a heart valve prosthesis ánd undergoing coronary revascularisation through a better understanding of their demographics, antithrombotic management and related in-hospital and long-term outcomes. The WOEST 2 Registry will provide data to support benchmarking of antithrombotic treatment patterns and patient outcomes.

Objective: To assess the different management patterns and related in-hospital and long-term safety and efficacy outcomes of combined use of chronic oral anticoagulation and a P2Y12 inhibitor in patients with atrial fibrillation and/or a heart valve prosthesis undergoing coronary revascularisation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Composite of the rate of non-fatal myocardial infarction, non-fatal ischemic stroke (including transient ischemic attack), non-central nervous system systemic embolization and cardiovascular death [the primary efficacy outcome].

    Measured: 1 year

  2. The occurrence of any bleeding episode requiring in-hospital medical attention and/or a switch of antithrombotic medication [the primary safety outcome].

    Bleeding will be classified by the Bleeding Academic Research Consortium (BARC) 2, 3, 4 and 5 bleeding criteria and by the Thrombolysis in Myocardial Infarction (TIMI) minor and major bleeding criteria.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillations and Heart Valve Prostheses, run by R&D Cardiologie at 9 sites in 2 countries.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in Belgium, Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Wilbert Bor, MD (+31640907188, w.bor@antoniusziekenhuis.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite of the rate of non-fatal myocardial infarction, non-fatal ischemic stroke (including transient ischemic attack), non-central nervous system systemic embolization and cardiovascular death [the primary efficacy outcome]. (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2020.
