About this study
Official title: Contemporary Antithrombotic Treatment in Patients With Non-valvular AF Undergoing PCI: The Greek AntiPlatElet Atrial Fibrillation (GRAPE-AF) Registry.
Approximately 5% to 7% of patients undergoing percutaneous coronary intervention for the treatment of coronary artery disease, require chronic oral anticoagulation on top of aspirin and a P2Y12 receptor antagonist, mainly due to non-valvular atrial fibrillation. Advent of non-vitamin K antagonist oral anticoagulants (NOAC) increased treatment options, while there is cumulative evidence that dual combination of NOAC and P2Y12 receptor antagonist attenuates bleeding without compromising efficacy. Greek AntiPlatElet Atrial Fibrillation (GRAPE-AF) is an observational study of non-valvular atrial fibrillation patients undergoing percutaneous coronary intervention, planning to enroll >500 participants during 1 year period in Greece. Patients will be followed-up at 1, 6 and 12 months post hospital discharge. Key data to be collected pre-discharge include demographics, detailed past medical history, antithrombotic and concomitant treatment. Study's primary endpoint is clinically significant bleeding defined as Bleeding Academic Research Consortium (BARC) ≥2) at 12 months, between vitamin K antagonists (VKAs) and NOACs-treated patients. All clinical events will be adjudicated by an independent endpoint committee.This study would provide "real world" information on current antithrombotic treatment patterns and clinical outcome of patients with non-valvular atrial fibrillation undergoing percutaneous coronary intervention.
Read the detailed description
All consecutive patients undergoing percutaneous coronary intervention over 1 year period will be screened for participation. Discharge antithrombotic medication will be at the discretion of the treating physician.
Follow-up visits will be performed at 1, 6 and 12 months post-percutaneous coronary intervention by telephone contact or personal interview. All outcome and adverse events will be adjudicated by an independent endpoint committee. All data will be recorded in electronic forms and multiple quality controls will be performed both electronically and on-site to ensure data integrity.
Platelet reactivity substudy:Patients receiving either clopidogrel or ticagrelor as part of their (dual or triple) combination therapy, will be eligible for sub-study of platelet function assessment with the VerifyNow assay at 1 month post-percutaneous coronary intervention in centers with test availability.
Sub-study's endpoints will be platelet reactivity between groups and high platelet reactivity rate between groups.

Questions about this trial
What is this clinical trial studying?
An observational study of Atrial Fibrillation and Coronary Artery Disease, run by Attikon Hospital at 1 site in Greece.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 10 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: finished, as of the sponsor's last update on 26 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Greece. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clinically significant bleeding (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03362788, which also lists 2 linked publications.
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 26 Jul 2021; AzTrials last refreshed its copy on 8 Nov 2026.
