Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Traditionally, coronary angiograms are performed through the radial artery which is accessed above the palm of the 'right' hand. In recent years, some cardiologists are performing this procedure from the back of the wrist in as the radial artery courses through the anatomical snuffbox (distal radial access). The aim of this study is to determine the prevalence of hand dysfunction following coronary angiography via the distal radial artery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

1. Age ≥ 18 years.
2. The distal radial artery must be palpable and non-occlusive flow must be confirmed by Doppler ultrasound.
3. Patient should be able to comply with the protocol.
4. 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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

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

Exclusion Criteria

1. Obligatory femoral or forearm radial access
2. Previous ipsilateral forearm radial artery occlusion.
3. Undergoing another procedure involving the ipsilateral radial artery, performed between the index procedure and the follow-up date.
4. Enrolment in another study that competes or interferes with this study.
5. Poor clinical condition like cardiogenic shock, that prohibits pre- and postprocedural function tests.
6. 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.
7. Co-morbidity that excludes patient follow-up.
