DOACs: continue or pause around elective heart artery procedures
Official title: Comparison Between Direct Oral Anticoagulation (DOAC) Interruption and DOAC Continuation in Patients Undergoing Elective Invasive Coronary Angiography or Percutaneous Coronary Intervention
Run by Zuyderland Medisch Centrum · NCT04977076 · Data updated 2026-11-12
This study tests whether continuing DOAC blood thinners during elective coronary angiography or PCI is safe for adults with atrial fibrillation and coronary artery disease.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 on a DOAC undergoing elective ICA or PCI who provide informed consent.
✕Probably not a fit
Patients with high bleeding risk or certain exclusion criteria may not benefit or could be at higher risk if DOACs are continued.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, multicenter, randomized trial where adults on a DOAC undergoing elective ICA or PCI are assigned to continue DOACs or interrupt them. The primary aim is to evaluate safety outcomes of uninterrupted DOAC use around the procedure. The trial is investigator-initiated, with parallel groups in real-world clinical settings. Enrollment is 1:1, and no DOAC dose adjustments are mandated before the procedure. Outcomes will inform guidelines on periprocedural DOAC management in this patient population.
Why it matters
Potential benefit: If uninterrupted DOAC use is safe, patients may avoid stopping anticoagulation and reduce thromboembolic risk around procedures.
How similar studies have gone: There is limited large trial evidence on uninterrupted DOAC use around ICA/PCI; this study addresses a gap in high-quality data.
