Evaluation of potential nerve damage after radial CAG/PCI.
Prospective patients scheduled for radial CAG/ PCI will be enrolled in the study. Prior to the procedure, sensory and motor nerve examination is performed at the wrists in both arms / hands. The examination is performed on both the median nerve and the ulnar nerve. Each patient acts as their own control. The nerve test is repeated bilaterally 1 month after the procedure. This creates 2 groups, A and B. Patients will be asked to complete 2 questionnaires in relation to hand and arm symptoms. The patients ability to perform certain activities before and after the CAG/PCI procedure are also addressed. In addition, a diagnostic tool (Katz chart) will be completed, also before and after the CAG/PCI procedure. Hypothesis: Radial access is associated with an increased risk of pain and an increased incidence of nerve damage similar to the median nerve at the carpal tunnel or the ulnar nerve at the Guyon's canal.

RECRUITINGNeurophysiological measurements
The primary aim is the incidence/presence of electrofysiological signs of median and/or ulnar nerve lesion at the wrist and the presence of carpaltunnel syndrom. The electrodiagnosis of carpaltunnelsyndrom will be determined from the clinical picture and signs of prolonged distal motor lantency and reduced motor and sensory nerveconduction velocity across the wrist and/or reduced amplitudes of the median nerve and normal ulnar nerve at the wrist.
