ClinConnect Summary

This clinical trial is studying whether the exact spot where the radial artery (a blood vessel in the wrist) is accessed during a heart procedure affects the chance of experiencing a radial artery spasm. A radial artery spasm is when the artery tightens suddenly, which can cause discomfort and make the procedure more difficult. The study will compare two different puncture sites on the wrist to see if one leads to fewer spasms and a smoother experience during coronary angiography, a test that looks at the heart’s blood vessels.

Adults aged 18 and older who are scheduled for coronary angiography using the radial artery and have a normal blood flow test in the wrist (called the Allen test) may be eligible. Participants will be randomly assigned to have the artery accessed either closer or a bit farther away from a specific wrist bone. The procedure will be done by experienced doctors using standard methods and medications. Throughout the study, the team will watch for artery spasms and any other complications to find the best puncture site that helps reduce spasms and improves patient comfort.
