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.
