Incidence and Predictors of Radial Artery Spasm in Transradial Coronary Angiography

INTRODUCTION The occurenceof radial artery spasm (RAS) during angiography offsets the advantages of this route of access, increasing the degree of patient discomfort and reducing the chances of a successful catheterization. AIMS AND OBJECTIVES To estimate the incidence of Radial artery spasm in patients undergoing transradial coronary angiography and to assess the predictors of Radial artery spasm in coronary angiography. STUDY DESIGN-Prospective observational study OBSERVATIONS AND RESULTS During study 26.3 % patients develop radial artery spasm.15.3 % develop radial artery occlusion. Female sex in an independent predictor of RAS with significantp-value (1 catheter / single catheter, was statistically significant (p=
