Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
When doctors perform heart catheterization through the radial artery in your wrist, sometimes that artery becomes blocked afterward — a condition called radial artery occlusion. This trial tests whether a medication called , a blood thinner, can help restore blood flow to that artery when it becomes blocked. Researchers will compare patients who receive the medication for 4 weeks with patients who do not receive any blood-thinning treatment.
Radial artery blockage can cause pain, numbness, and weakness in the forearm, and it can prevent doctors from using that artery for future procedures. While some arteries reopen on their own over time, many do not — and doctors need better ways to treat this problem when it occurs.

If you are diagnosed with a blocked radial artery after your heart catheterization, you will be randomly assigned to either take the medication for 4 weeks or receive no blood-thinning treatment as a control. You will have ultrasound imaging of your arm performed right after your procedure, and then again at 1, 2, and 4 weeks after your catheterization to see if your artery reopens and to monitor your progress.
