The aim of project NUSHI is to elucidate, that radial sheath insertion can be performed by nurses and physicians with the same level of comfort and safety.

Background: Insertion of sheath in the radial artery in connection with examination and treatment of patients with coronary artery disease is usually performed by specialized invasive cardiologists or trainees. Whether sheath insertion can be performed by nurses with the same level of comfort and pain is uncertain.

Eligibility: Patients referred for coronary angiography (CAG) and/or percutaneous coronary intervention (PCI) due to suspicion of coronary artery disease are included

Randomization: Patients are randomized 1:1 to sheath insertion by nurse or physician

Methods: Insertion of 5 or 6 radial sheaths is performed in local anesthesia

Outcome measures: Comfort and pain level is registered from immediately after sheath insertion until start of CAG/PCI.

Additional outcome measures: Oximetry test is performed immediately after sheath removal - and repeated after 1 month in case of occlusion. Any complication is recorded from the patient enters the wake-up room until discharge.

All patients are contacted after 1 year in order to register adverse events.

Inclusion Criteria:

• patients suspected of having coronary artery disease
• with normal puls oxymetry on the right hand
• understands patient information and accepts to participate

Exclusion Criteria:

• under consideration for cardiac valve replacement
• systolic blood pressure persistently >180 mmHg
