Brief Summary
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.

Eligibility Criteria
Eligible patients for inclusion are those by whom coronary angiography or angioplasty is indicated as part of clinical decision-making or therapy. Operators with adequate experience at the discretion of the principal investigator in distal radial access are eligible to participate.
You may qualify if:
- 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.
You may not qualify if:
- 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.
