Conditions
Patients Undergoing Diagnostic Coronary Angiography
Registration Number
NCT04301921
Lead Sponsor
Prof. Dr. med. Ingo Eitel
Brief Summary

Primary Outcome Measures
NameTimeMethod
Bleeding eventsDay 1

Will be bleeding events according to Bleeding Academic Research Consortium (BARC) criteria.

Occurrence of postprocedural RAODay 1

Will be the occurrence of postprocedural RAO 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.

Secondary Outcome Measures
NameTimeMethod
Sonographic characteristics of radial artery occlusion3 Month

Occlusion lengths or minimal residual perfusion
