Coronary angiography (CAG) is an invasive imaging method performed to determine the degree of coronary artery disease. Radial artery spasm (RAS) is one of the most common complications during coronary angiography performed via the transradial approach, causing patient discomfort or sometimes interrupting the procedure. There are many studies on RAS, and various pharmacoagents administered intravenously (intraarterial) to prevent RAS have been described. However, there is limited data in the literature regarding oral pharmacoagents that will prevent this complication. In our study, the preventive effect of Verapamil, given orally 2 hours before coronary angiography, on radial artery spasm will be investigated.
