Heparin use for diagnostic cardiac catheterization with a radial artery approach: An international survey of practice patterns

OBJECTIVES: We aimed to describe global practice patterns of unfractionated heparin (UFH) use for diagnostic transradial cardiac catheterization. BACKGROUND: The use of the radial artery approach for cardiac catheterization is increasing globally. Limited contemporary data exist to support the use or optimal dosing of UFH to prevent radial artery occlusion (RAO) and other thromboembolic complications.
