Observational Study of Hand Function After Distal Transradial Access for Angiography

In this multi centre observational registry, we will recruit patients undergoing planned invasive coronary angiography. Inclusion criteria include:

• Age ≥ 18 years.
• The distal radial artery must be palpable and non-occlusive flow must be confirmed by Doppler ultrasound.
• Patient should be able to comply with the protocol.
• Provide written informed consent before study participation.

The primary endpoint is the overall prevalence of hand dysfunction defined as any significant reduction from baseline score in any of the following five domains:

DASH score Levine Katz score VAS score Sensory function Pinch grip strength.

Specifically hand function will be assessed at 4 time points using simple tests of hand strength, sensation and ultrasound to assess the arterial latency.

Inclusion criteria

• Age ≥ 18 years.
• The distal radial artery must be palpable and non-occlusive flow must be confirmed by Doppler ultrasound.
• Patient should be able to comply with the protocol.
• Provide written informed consent before study participation.

Exclusion criteria

• Obligatory femoral or forearm radial access
• Previous ipsilateral forearm radial artery occlusion.
• Undergoing another procedure involving the ipsilateral radial artery, performed between the index procedure and the follow-up date.
• Enrolment in another study that competes or interferes with this study.
• Poor clinical condition like cardiogenic shock, that prohibits pre- and postprocedural function tests.
• Any other condition which, in the opinion of the investigator or operator, may pose a significant hazard to the subject if he or she is enrolled in the study.
• Co-morbidity that excludes patient follow-up.
