Strategies to Maintain Radial Artery Patency Following Diagnostic Coronary Angiography - Subgroup of Patients on Oral Anticoagulants (RAPID-2)

May 8, 2020 updated by: Prof. Dr. med. Ingo Eitel, University of Luebeck
To investigate whether omitting systemic anticoagulation during transradial coronary angiography and/or a distal radial access reduce the risk of postprocedural radial artery occlusion

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Occurrence of postprocedural radial artery occlusion
Time Frame: Day 1
Will be the occurrence of postprocedural radial artery occlusion assessed with high-resolution vascular ultrasound. Experienced sonographers will perform color Doppler ultrasound in all study patients after removal of the compression device to examine the radial, ulnar, and brachial arteries of the access forearm.
Day 1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sonographic characteristics of radial artery occlusion
Time Frame: 3 Month
Occlusion lengths or minimal residual perfusion
3 Month
