Cassidy Harmon (2016) conducted a cohort in Radial Artery Spasm (RAS) during transradial cardiac catheterization (n=88). Nitroglycerin and Verapamil vs. Verapamil alone was evaluated on Incidence of Radial Artery Spasm (RAS) (p=0.589). A spasmolytic cocktail of nitroglycerin and verapamil did not significantly reduce the incidence of radial artery spasm compared to verapamil alone (4.5% vs 9.5%, p=0.589) in patients undergoing transradial cardiac catheterization.
