Retrospective Analysis of Angiographic Radial Artery Spasm Predictors

Our findings suggest that low body weight and small radial artery diameter are significant independent predictors of angiographic radial artery spasm, highlighting the importance of anatomical considerations over demographic or clinical factors. Preprocedural assessment of radial artery size may enhance risk stratification and guide preventive strategies. Further multicenter validation is warranted. Incorporating routine evaluation of radial artery size and body habitus into pre-procedural assessment may help identify patients who could benefit from tailored preventive approaches-such as smaller sheath sizes, increased vasodilator use, or ultrasound-guided puncture-to optimize procedural success and patient comfort.
